Contact lens and product thereof

Abstract

A contact lens includes a central area, a ring area, and a peripheral area. The central area contains the center point of the contact lens, the ring area symmetrically surrounds the central area, and the peripheral area symmetrically surrounds the ring area. The contact lens includes at least one color sample, and the ring area includes at least two critical point values. Under certain conditions, the increase in refractive power away from the central area can be mitigated, thus providing a more moderate degree of defocus, which helps improve the comfort of wearing the lens for extended periods, and is therefore beneficial for preventing or controlling myopia.

Description

Technical Field

[0001] This invention relates to a contact lens and a contact lens product, and more particularly to a contact lens and a contact lens product that can mitigate the increase in refractive power away from the central area and can prevent or control myopia. Prior Technology

[0002] Traditional contact lenses with vision control typically feature a rapid increase in refractive power after leaving the central area. This drastic change in refractive power causes significant discomfort for the wearer, making it difficult to adhere to treatment regimens for extended periods and significantly reducing the effectiveness of vision control. Furthermore, traditional contact lenses with front-and-back recognition features have microgrooves or raised dots on their surface. However, the microgrooves are prone to breakage, and the raised dots can cause severe foreign body sensation. In addition, traditional contact lenses with vision control cannot control light transmission; excessive light transmission can cause photophobia, while insufficient light transmission results in blurred vision. Therefore, improving the structure of contact lenses to provide vision control while avoiding these shortcomings has become a goal for manufacturers. Summary of the Invention

[0003] One objective of this invention is to provide a contact lens and a contact lens product, wherein the contact lens can prevent or control myopia, and its annular area includes at least one critical point, which can effectively mitigate the increase in refractive power away from the central area, improve wearing comfort, and help increase the possibility of long-term treatment.

[0004] According to the present invention, a contact lens is provided, comprising a central region, a ring region, and a peripheral region. The central region contains the center point of the contact lens, the ring region symmetrically surrounds the central region, and the peripheral region symmetrically surrounds the ring region. The peripheral region contains at least one color sample portion, and the ring region contains at least two critical point values, which are a first critical point value and a second critical point value from the inside out. The maximum diameter of the central region is DiC, the refractive power of the central region is POWC, the maximum refractive power of the ring region is PPmax, the first critical point value is PCP1, and the second critical point value is PCP2, satisfying the following conditions: 2.0 mm < DiC ≤ 4.5 mm; 2.00 D ≤ |PPmax-POWC| ≤ 18.00 D; and -14.00 D ≤ PCP2-PCP1 ≤ 16.00 D.

[0005] According to the present invention, a contact lens product is further provided, comprising the aforementioned contact lens and an immersion solution, wherein the contact lens is immersed in the immersion solution, and at least one of the contact lens and the immersion solution contains a cycloplegic agent.

[0006] When DiC meets the above conditions, it can provide a clear central field of vision depending on the wearer's condition and help reduce discomfort when wearing it.

[0007] When PPmax-POWC meets the above conditions, it can provide a more moderate degree of defocus, which helps to reduce the discomfort of wearing it for a long time and provides longer usability to achieve the purpose of myopia control.

[0008] When PCP2-PCP1 meet the above conditions, the discomfort that may be caused by defocus design can be avoided. Simple Explanation of the Diagram

Implementation

[0010] <First Implementation Method>

[0011] Figure 1 illustrates a schematic diagram of the partitions of a contact lens 100 according to a first embodiment of the present invention. In Figure 1, the contact lens 100 includes a central area 110, a ring area 120, and a peripheral area 130. The central area 110 includes the center point O of the contact lens 100. The ring area 120 symmetrically surrounds the central area 110, and the peripheral area 130 symmetrically surrounds the ring area 120. The ring area 120 includes at least one critical point value. By setting the critical point value, a phased large or small amplitude mitigation effect can be provided, which can effectively mitigate the increase in refractive power away from the central area 110, improve wearing comfort, and help increase the possibility of long-term treatment.

[0012] The central zone 110 has a POWC (Power of Light) that meets the following condition: -0.50 D ≤ POWC ≤ 0.50 D. This ensures that light is well focused on the retina when used in patients with a potential tendency towards myopia, providing a clear and comfortable image. Specifically, the central zone 110 is configured with a low or no power, combined with an appropriate and gentle defocus design in the annular zone 120, allowing light to be focused in front of the retina to achieve myopia prevention and avoid axial elongation. Alternatively, it can meet the following condition: -0.25 D ≤ POWC ≤ 0.25 D.

[0013] The refractive power of central zone 110 is POWC, which satisfies the following condition: -8.00 D ≤ POWC < 0 D. Therefore, when used in patients with low to moderate myopia, the refractive power of central zone 110 can provide myopia correction. The refractive power of central zone 110 can be adjusted as needed to ensure good focusing of light onto the retina, providing a clear and comfortable image. Alternatively, it can satisfy the following conditions: -7.00 D ≤ POWC ≤ -0.25 D. Alternatively, it can satisfy the following conditions: -6.50 D ≤ POWC < 0 D. Alternatively, it can satisfy the following conditions: -5.50 D ≤ POWC < 0 D. Alternatively, it can satisfy the following conditions: -4.50 D ≤ POWC < 0 D.

[0014] The central zone 110 has a refractive power of POWC, and the annular zone 120 has a maximum refractive power of PPmax, satisfying the following condition: 2.00 D ≤ |PPmax-POWC| ≤ 20.00 D. Therefore, the annular zone 120 is designed with increased refractive power, allowing light from the annular zone 120 to focus in front of the retina. This defocusing effect helps prevent and control myopia, effectively avoiding axial elongation. Alternatively, it can satisfy the following condition: 2.00 D ≤ |PPmax-POWC| ≤ 8.00 D. Alternatively, it can satisfy the following condition: 3.50 D ≤ |PPmax-POWC| ≤ 19.00 D. Alternatively, it can satisfy the following condition: 5.50 D ≤ |PPmax-POWC| ≤ 17.00 D. Alternatively, it can satisfy the following condition: 8.00 D ≤ |PPmax-POWC| ≤ 15.00 D. Alternatively, it can satisfy the following condition: 9.50 D ≤ |PPmax-POWC| ≤ 15.50 D.

[0015] The maximum refractive power of the annular zone 120 is PPmax, which satisfies the following condition: 0 D ≤ PPmax ≤ 15.00 D. This allows for appropriate enhancement of the defocus effect outside the central zone 110 according to the wearer's needs. Alternatively, it can satisfy the following condition: 0.50 D ≤ PPmax ≤ 13.00 D. Alternatively, it can satisfy the following condition: 1.50 D ≤ PPmax ≤ 12.50 D. Alternatively, it can satisfy the following condition: 2.00 D ≤ PPmax ≤ 10.5 D. Alternatively, it can satisfy the following condition: 2.00 D ≤ PPmax ≤ 9.00 D.

[0016] The annular region 120 may contain at least one high critical point value, which is PPH, satisfying the following condition: -5.00 D ≤ PPH ≤ 20.00 D. This mitigates the degree of change in refractive power. Alternatively, it may satisfy the following condition: -5.00 D ≤ PPH ≤ 18.00 D, or -3.00 D ≤ PPH ≤ 16.00 D, or -1.00 D ≤ PPH ≤ 16.00 D, or -1.00 D ≤ PPH ≤ 14.00 D.

[0017] The annular region 120 may include at least one critical point value, the critical point value of which is PPM, satisfying the following condition: -6.00 D ≤ PPM ≤ 0 D. This provides a partially clear focusing area around the retina, reducing discomfort when wearing the contact lens 100. Alternatively, it may satisfy the following condition: -3.00 D ≤ PPM ≤ 0 D.

[0018] The annular region 120 may contain at least one low critical point value, which is PPL, and satisfies the following condition: -10.00 D ≤ PPL ≤ 0 D. This increases the design freedom for refractive power enhancement and has a mitigating effect on refractive power changes. Alternatively, it may satisfy the following condition: -9.00 D ≤ PPL ≤ 0 D. Or, it may satisfy the following condition: -4.00 D ≤ PPL ≤ 0 D.

[0019] The annular zone 120 may include at least one high critical point value. The maximum refractive power of the annular zone 120 is PPmax, and the high critical point value is PPH, which can satisfy the following condition: -5.00 ≤ PPmax / PPH ≤ 60.00. This allows for setting an optimal level of defocus in the central zone 110 according to the wearer's condition. Furthermore, setting the high critical point value helps to progressively increase the level of defocus, reducing discomfort from high defocus designs at the periphery. Alternatively, it can satisfy the following condition: -5.00 ≤ PPmax / PPH ≤ 30.00. Alternatively, it can satisfy the following condition: -5.00 ≤ PPmax / PPH ≤ 20.00. Alternatively, it can satisfy the following condition: -3.00 ≤ PPmax / PPH ≤ 20.00. Alternatively, it can satisfy the following condition: -5.00 ≤ PPmax / PPH ≤ 15.00. Alternatively, it may satisfy the following conditions: -3.00 ≤ PPmax / PPH ≤ 18.00. Alternatively, it may satisfy the following conditions: -3.00 ≤ PPmax / PPH ≤ 15.00. Alternatively, it may satisfy the following conditions: -3.00 ≤ PPmax / PPH ≤ 10.00. Alternatively, it may satisfy the following conditions: -3.00 ≤ PPmax / PPH ≤ 9.00. Alternatively, it may satisfy the following conditions: -3.00 ≤ PPmax / PPH ≤ 5.00.

[0020] The annular zone 120 may include at least one low critical point value. The maximum refractive power of the annular zone 120 is PPmax, and the low critical point value is PPL, which can satisfy the following condition: -40.00 ≤ PPmax / PPL ≤ 0. This allows for setting a better degree of defocus outside the central zone 110 according to the wearer's condition. Setting the low critical point value helps to gradually mitigate the degree of defocus, reducing the design difficulty of high defocus. Alternatively, it can satisfy the following conditions: -30.00 ≤ PPmax / PPL ≤ 0. Alternatively, it can satisfy the following conditions: -25.00 ≤ PPmax / PPL ≤ 0. Alternatively, it can satisfy the following conditions: -20.00 ≤ PPmax / PPL ≤ 0. Alternatively, it can satisfy the following conditions: -15.00 ≤ PPmax / PPL ≤ 0. Alternatively, it can satisfy the following conditions: -10.00 ≤ PPmax / PPL ≤ 0.

[0021] The maximum diameter of the central area 110 is DiC, which can satisfy the following conditions: 1.0 mm ≤ DiC ≤ 4.5 mm. This provides a clear central field of vision depending on the wearer's condition and helps reduce discomfort during wear. Alternatively, it can satisfy the following conditions: 1.4 mm ≤ DiC ≤ 4.5 mm. Alternatively, it can satisfy the following conditions: 1.4 mm ≤ DiC ≤ 3.5 mm. Alternatively, it can satisfy the following conditions: 2.0 mm ≤ DiC ≤ 3.0 mm.

[0022] The maximum diameter of the annular zone 120 is DiP, which satisfies the following condition: DiP ≤ 8.0 mm. This provides an appropriate range for the annular zone 120 to achieve myopia control and prevention.

[0023] The annular region 120 may contain at least one critical point value, with the critical point value closest to the center point O being the first critical point value, and the first critical point value may be a low critical point value. In this way, the refractive power can be moderately reduced and the change in refractive power can be mitigated, reducing the discomfort caused to the wearer by defocus.

[0024] The annular region 120 may contain at least two critical point values, namely a first critical point value and a second critical point value from the inside out, wherein the first critical point value may be a high critical point value. In this way, an immediate increase in refractive power can be achieved on the inner side of the annular region 120, which helps to enhance the intensity of myopia prevention or control.

[0025] The first critical point value can be a high critical point value, and the second critical point value can be a low critical point value. When the first critical point is a high critical point, the refractive power can be immediately increased within the 120° ring area, which helps to enhance the intensity of myopia prevention or control. When combined with the second critical point being a low critical point, the refractive power can be moderately reduced and the change in refractive power can be mitigated, reducing the discomfort caused by defocus to the wearer.

[0026] The second critical point value can be a high critical point value. This helps to increase the degree of defocus, thereby achieving the effect of preventing or controlling myopia in a short period of time.

[0027] The second critical point value can be the middle critical point value. This helps to mitigate the degree of defocusing, allowing the 120° portion of the ring area to have a clear focus effect, thereby increasing the wearer's visual comfort.

[0028] The second critical point value can be a low critical point value. This helps to mitigate the degree of defocus and reduce discomfort when wearing the device.

[0029] The refractive power of the central zone 110 is POWC, and the first critical point value is PCP1, which can satisfy the following condition: 0 D < PCP1 - POWC ≤ 3.80 D. Therefore, designing an optimal difference in refractive power between the first critical point and the center helps to appropriately increase the degree of defocus by a small margin, thereby improving the effect of myopia prevention or control. Alternatively, it can satisfy the following condition: 0 D < PCP1 - POWC ≤ 3.5 D.

[0030] The refractive power of the central zone 110 is POWC, and the first critical point value is PCP1, which can satisfy the following condition: 4.00 D ≤ PCP1 - POWC ≤ 20.00 D. Therefore, designing an optimal difference between the first critical point and the refractive power of the central zone 110 helps to adjust the defocus level appropriately and in stages, improving the effectiveness of myopia prevention or control. Alternatively, it can satisfy the following condition: 4.5 D ≤ PCP1 - POWC ≤ 18 D. Or, it can satisfy the following condition: 4.5 D ≤ PCP1 - POWC ≤ 10 D.

[0031] The refractive power of the central zone 110 is POWC, and the first critical point value is PCP1, which satisfies the following condition: -6.00 D ≤ PCP1 - POWC ≤ 10 D. Therefore, designing an optimal difference between the first critical point and the refractive power of the central zone 110 helps to appropriately adjust the degree of defocus, improving the effect of myopia prevention or control. Alternatively, it can satisfy the following conditions: -6.00 D ≤ PCP1 - POWC < 0 D. Alternatively, it can satisfy the following conditions: -5.00 D ≤ PCP1 - POWC < 0 D. Alternatively, it can satisfy the following conditions: -4.00 D ≤ PCP1 - POWC < 0 D.

[0032] The first critical point value is PCP1, and the second critical point value is PCP2, which can satisfy the following condition: -14.00 D ≤ PCP2 - PCP1 ≤ 16.00 D. In this way, the discomfort that may be caused by defocus design can be avoided.

[0033] The first critical point value is PCP1, and the second critical point value is PCP2, which can satisfy the following condition: -7.00 D ≤ PCP2 - PCP1 ≤ 0 D. Therefore, by designing an optimal difference in refractive power between the second and first critical points to slightly reduce the refractive power, discomfort that may be caused by defocusing can be mitigated and avoided. Alternatively, it can satisfy the following condition: -6.00 D ≤ PCP2 - PCP1 ≤ 0 D. Or, it can satisfy the following condition: -5.00 D ≤ PCP2 - PCP1 ≤ 0 D.

[0034] The first critical point value is PCP1, and the second critical point value is PCP2, which can satisfy the following condition: -14.00 D ≤ PCP2 - PCP1 ≤ -7.50 D. Therefore, by designing an optimal difference in refractive power between the second and first critical points, a significant reduction in refractive power can be achieved, quickly alleviating discomfort that may be caused by defocusing. Alternatively, it can satisfy the following condition: -12.00 D ≤ PCP2 - PCP1 ≤ -7.50 D. Or, it can satisfy the following condition: -10.00 D ≤ PCP2 - PCP1 ≤ -7.50 D.

[0035] The refractive power of the central zone 110 is POWC, with the first critical point value being PCP1 and the second critical point value being PCP2. This satisfies the following condition: -25 ≤ (PCP2 - PCP1) / (PCP1 - POWC) ≤ 0. This reduces discomfort and increases the success rate of myopia prevention or control.

[0036] The refractive power of the central zone 110 is POWC, with the first critical point value being PCP1 and the second critical point value being PCP2. This satisfies the following condition: -1.75 ≤ (PCP2 - PCP1) / (PCP1 - POWC) ≤ 0. This allows for the design of an optimal ratio of refractive power differences, achieving a more gradual defocus design with small changes in refractive power. This facilitates long-term wear and gradual adaptation for the wearer, improving the success rate of myopia prevention or control. Alternatively, it can satisfy the following condition: -1.6 ≤ (PCP2 - PCP1) / (PCP1 - POWC) ≤ 0.

[0037] The refractive power of the central zone 110 is POWC, with a first critical point value of PCP1 and a second critical point value of PCP2. This satisfies the following condition: -25 ≤ (PCP2 - PCP1) / (PCP1 - POWC) ≤ -1.9. Therefore, a better ratio of refractive power difference is designed to achieve a greater degree of defocus with a larger range of refractive power changes, helping wearers achieve myopia prevention or control effects in a short period. Alternatively, it can satisfy the following condition: -15 ≤ (PCP2 - PCP1) / (PCP1 - POWC) ≤ -2.

[0038] The annular region 120 may contain at least three critical point values, namely, a first critical point value, a second critical point value, and a third critical point value, from the inside out. The second critical point value is PCP2, and the third critical point value is PCP3, which can satisfy the following condition: -20.00 D ≤ PCP3 - PCP2 ≤ 20.00 D. This can reduce discomfort and improve the effectiveness of myopia prevention or control.

[0039] The second critical point value is PCP2, and the third critical point value is PCP3, which can satisfy the following condition: 0 D ≤ PCP3 - PCP2 ≤ 12.00 D. Therefore, by designing an optimal difference in refractive power between the third and second critical points, a slight increase in refractive power can be achieved, thereby improving the patient's adaptability to myopia prevention or control treatment.

[0040] The second critical point value is PCP2, and the third critical point value is PCP3, which can satisfy the following condition: 14.00 D ≤ PCP3 - PCP2 ≤ 20.00 D. Therefore, by designing an optimal difference in refractive power between the third and second critical points to significantly increase the refractive power, a stronger effect can be achieved in preventing or controlling myopia.

[0041] The third critical point value can be a high critical point value. This helps to increase the degree of defocus, thereby achieving the effect of preventing or controlling myopia in a short period of time.

[0042] The third critical point value can be the middle critical point value. This helps to mitigate the degree of defocusing, allowing the 120° portion of the annular area to have a clear focus effect, thereby increasing the wearer's visual comfort.

[0043] The third critical point value can be a low critical point value. This helps to mitigate the degree of defocus and reduce discomfort when wearing the device.

[0044] The annular region 120 may contain at least four critical point values, namely, a first critical point value, a second critical point value, a third critical point value, and a fourth critical point value, from the inside out. The third critical point value is PCP3, and the fourth critical point value is PCP4, which can satisfy the following condition: -15.00 D ≤ PCP4 - PCP3 ≤ 12.00 D. This allows for a significant increase in refractive power, achieving a stronger effect in preventing or controlling myopia.

[0045] The fourth critical point value can be a high critical point value. This helps to increase the degree of defocus, thereby achieving the effect of preventing or controlling myopia in a short period of time.

[0046] The fourth critical point value can be a low critical point value. This helps to mitigate the degree of defocus and reduce discomfort when wearing the device.

[0047] The annular region 120 may contain at least five critical point values, from the inside out: the first critical point value, the second critical point value, the third critical point value, the fourth critical point value, and the fifth critical point value. The fourth critical point value is PCP4, and the fifth critical point value is PCP5. These values ​​must satisfy the following condition: -5.00 D ≤ PCP5 - PCP4 ≤ 5.00 D. This allows for a slight, gradual increase in refractive power, improving the patient's adaptability to myopia prevention or control treatment.

[0048] The fifth critical point value can be a high critical point value. This helps to increase the degree of defocus, thereby achieving the effect of preventing or controlling myopia in a short period of time.

[0049] The fifth critical point value can be a low critical point value. This helps to mitigate the degree of defocus and reduce discomfort when wearing the device.

[0050] The annular region 120 may contain at least six critical point values, from the inside out: the first critical point value, the second critical point value, the third critical point value, the fourth critical point value, the fifth critical point value, and the sixth critical point value. The fifth critical point value is PCP5, and the sixth critical point value is PCP6. These values ​​must satisfy the following condition: -5.00 D ≤ PCP6 - PCP5 ≤ 15.00 D. This allows for a significant increase in refractive power, achieving a stronger effect in preventing or controlling myopia.

[0051] The sixth critical point value can be a high critical point value. This helps to improve the degree of defocus, thereby achieving the effect of preventing or controlling myopia in a short period of time.

[0052] The sixth critical point value can be a low critical point value. This helps to mitigate the degree of defocus and reduce discomfort when wearing the device.

[0053] The aforementioned critical point values, high critical point values, low critical point values, and intermediate critical point values ​​are defined as follows: The annular area 120 of the contact lens 100 may contain at least one critical point (not shown in the figure). The refractive power of the critical point is called the critical point value. Based on the relationship between the critical point value and the refractive power of the central area 110, the critical points are divided into high critical points (CH), low critical points (CL), and intermediate critical points (CM). A critical point with a critical point value higher than the refractive power of the central area 110 is called a high critical point, and its critical point value is called a high critical point value; a critical point with a critical point value lower than the refractive power of the central area 110 is called a low critical point, and its critical point value is called a low critical point value; a critical point with a critical point value equal to the refractive power of the central area 110 is called an intermediate critical point, and its critical point value is called an intermediate critical point value.

[0054] <Second Implementation Method>

[0055] Figure 2A illustrates a schematic diagram of the partitions of a contact lens 200 according to a second embodiment of the present invention. Figure 2B illustrates a side view of the contact lens 200 in Figure 2A, and Figure 2C illustrates a top view of the contact lens 200 in Figure 2A. In Figures 2A to 2C, the contact lens 200 includes a central region 210, an annular region 220, and a peripheral region 230. The central region 210 includes the center point O of the contact lens 200. The annular region 220 symmetrically surrounds the central region 210, and the peripheral region 230 symmetrically surrounds the annular region 220. The annular region 220 includes at least one critical point value. The peripheral region 230 may include at least one color sample portion.

[0056] Specifically, in the second embodiment, the peripheral area 230 includes two color samples, namely a first color sample 240A and a second color sample 240B. The pattern of the first color sample 240A is ring-shaped, and the pattern of the second color sample 240B is radial. The color of the first color sample 240A can be selected from red, orange, yellow, green, blue, indigo, violet, black, white, silver, or gold. The color of the second color sample 240B is different from the color of the first color sample 240A. Thus, different colors have different visible light transmission effects. Selecting an appropriate color can effectively control the light transmission ability (increasing or decreasing luminous flux). Darker color samples can reduce photophobia, while lighter color samples can increase luminous flux. Furthermore, the lower light transmittance of the color samples provides a high degree of light-blocking effect, reducing glare and stray light interference with visual control. At least two color samples, the first color sample 240A and the second color sample 240B, are provided, allowing for selective adjustment to reduce stray light effects.

[0057] In other embodiments, the minimum inner radius of the color sample portion may cover part of the annular area, thereby shielding stray light around the annular area and helping to avoid interfering with the imaging effect at the out-of-focus area, reducing discomfort for the wearer.

[0058] Other details regarding contact lens 200 are the same as those for contact lens 100 in Figure 1, and will not be repeated here.

[0059] <Third Implementation Method>

[0060] Figure 3A illustrates a schematic diagram of the partitions of a contact lens 300 according to a third embodiment of the present invention. Figure 3B illustrates a side view of the contact lens 300 in Figure 3A, and Figure 3C illustrates a top view of the contact lens 300 in Figure 3A. In Figures 3A to 3C, the contact lens 300 includes a central region 310, an annular region 320, and a peripheral region 330. The central region 310 includes the center point O of the contact lens 300. The annular region 320 symmetrically surrounds the central region 310, and the peripheral region 330 symmetrically surrounds the annular region 320. The annular region 320 includes at least one critical point value. The peripheral region 330 may include at least one color sample portion.

[0061] Specifically, in the third embodiment, the peripheral area 330 includes two color samples, namely a first color sample 340A and a second color sample 340B. The pattern of the first color sample 340A is circular, and the pattern of the second color sample 340B is multiple L-shapes. By configuring the second color sample 340B with a directional pattern, it helps to achieve the front and back identification function of the contact lens 300, which can improve the accuracy of wearing and increase the convenience and efficiency of wearing. The color of the first color sample 340A can be selected from red, orange, yellow, green, blue, indigo, violet, black, white, silver or gold, and the color of the second color sample 340B is different from the color of the first color sample 340A. Therefore, different colors have different visible light transmission effects. Selecting an appropriate color can effectively control the light transmission ability (increase or decrease the light flux). Dark color samples can reduce the light-sensitive effect, while light color samples can increase the light flux. In addition, the color sample has a low light transmittance and has a high light-blocking effect, reducing glare and stray light interference with visual control. At least two color samples, the first color sample 340A and the second color sample 340B, are set up, which can be selectively adjusted to reduce stray light effects.

[0062] In other embodiments, the minimum inner radius of the color sample portion may cover part of the annular area, thereby shielding stray light around the annular area and helping to avoid interfering with the imaging effect at the out-of-focus area, reducing discomfort for the wearer.

[0064] <Fourth Implementation Method>

[0065] Figure 4 illustrates a schematic diagram of the light-blocking ring 450 configuration of a contact lens 400 according to a fourth embodiment of the present invention. In Figure 4, the contact lens 400 includes a central area (not shown), an annular area (not shown), and a peripheral area (not shown). The central area includes the center point O of the contact lens 400, the annular area symmetrically surrounds the central area, and the peripheral area symmetrically surrounds the annular area. The annular area includes at least one critical point value. At least one light-blocking ring 450 may be included outside the central area of ​​the contact lens 400. Preferably, the light-blocking ring 450 is disposed in the annular area, thereby effectively eliminating stray light in the defocus area and improving the therapeutic effect of myopia control. Alternatively, the peripheral area may include at least one light-blocking ring 450 (extending from the annular area to the peripheral area, i.e., the peripheral area only includes a portion of the light-blocking ring 450), thereby preventing excessive light from entering the eye and causing photophobia, and maintaining sufficient light transmission to ensure image brightness.

[0066] In the fourth embodiment, the light-blocking rings 450 are uniformly distributed, thereby effectively reducing stray light interference and allowing for optimized design based on the wearer's pupil size. This prevents excessive light from entering the eyes and causing photophobia, while maintaining sufficient luminous flux to ensure image brightness. The aforementioned uniform distribution refers to a regular, intermittent, or fully filled design. However, the present invention is not limited to this.

[0067] In the fourth embodiment, the light-blocking ring 450 is solidly filled; however, in other embodiments, the light-blocking ring may be intermittently filled (see Figure 10) or dotted (see Figure 11). This prevents excessive light from entering the eyes and causing photophobia, and maintains sufficient light throughput to ensure image brightness.

[0068] The 450 light-blocking ring is available in a variety of colors, including red, orange, yellow, green, blue, indigo, violet, black, white, silver, or gold. Choosing the appropriate color can increase or decrease luminous flux; a darker 450 light-blocking ring reduces glare, while a lighter one increases brightness.

[0069] In the fourth embodiment, the minimum inner diameter of the light-blocking ring 450 is DBi, which satisfies the following condition: DBi = 7.04 mm. In other embodiments, the minimum inner diameter of the light-blocking ring is DBi, which satisfies the following condition: 3.5 mm ≤ DBi ≤ 11.0 mm. This avoids excessive light entering the eyes and causing photophobia, and maintains sufficient luminous flux to ensure image brightness. Alternatively, it can satisfy the following condition: 3.5 mm ≤ DBi ≤ 10 mm. Alternatively, it can satisfy the following condition: 4.5 mm ≤ DBi ≤ 10 mm. Alternatively, it can satisfy the following condition: 4.5 mm ≤ DBi ≤ 9 mm. Alternatively, it can satisfy the following condition: 4.5 mm ≤ DBi ≤ 8.5 mm.

[0070] In the fourth embodiment, the maximum outer diameter of the light-blocking ring 450 is DBo, which satisfies the following condition: DBo = 9.1 mm. In other embodiments, the maximum outer diameter of the light-blocking ring is DBo, which satisfies the following condition: 6 mm ≤ DBo ≤ 14 mm. This avoids excessive light entering the eyes and causing photophobia, and maintains sufficient luminous flux to ensure image brightness. Alternatively, it can satisfy the following condition: 6 mm ≤ DBo ≤ 13 mm. Alternatively, it can satisfy the following condition: 6.5 mm ≤ DBo ≤ 12.5 mm. Alternatively, it can satisfy the following condition: 6.0 mm ≤ DBo ≤ 11.0 mm. Alternatively, it can satisfy the following condition: 7.5 mm ≤ DBo ≤ 12.5 mm. Alternatively, it can satisfy the following condition: 8.5 mm ≤ DBo ≤ 11.5 mm.

[0071] In the fourth embodiment, the maximum outer diameter of the contact lens 400 is Do, which satisfies the following condition: Do = 14 mm. In other embodiments, the maximum outer diameter of the contact lens is Do, which satisfies the following condition: 13 mm ≤ Do ≤ 15 mm. This allows for the production of the most suitable contact lens size according to requirements.

[0072] In the fourth embodiment, the peripheral area of ​​the contact lens 400 may further include at least one color sample portion (not shown in the figures). Details regarding the color sample portion are the same as those of the contact lens 200 in Figures 2A to 2C or the contact lens 300 in Figures 3A to 3C, and will not be repeated here. Other details regarding the contact lens 400 are the same as those of the contact lens 100 in Figure 1, and will not be repeated here.

[0216] In the contact lens of the thirtieth embodiment, the first critical point is CP1, the second critical point is CP2, the third critical point is CP3, the fourth critical point is CP4, the fifth critical point is CP5, and the sixth critical point is CP6. For the types of the aforementioned critical points in the thirtieth embodiment, please refer to Table 44. Table 44, Example 30 CP1 CH CP4 - CP2 CM CP5 - CP3 CH CP6 -

[0217] As can be seen from the above embodiments, the contact lens of the present invention, by including at least one critical point, can effectively mitigate the increase in refractive power away from the central area by segmenting the degree of defocus and gradually mitigating the degree of defocus, thereby improving wearing comfort and helping to increase the possibility of long-term treatment.

[0218] According to the present invention, the central area of ​​the contact lens enables the wearer's central vision to focus clearly, but can also be reduced by 0.25 D to 0.50 D compared to the wearer's myopia to alleviate wearing discomfort. The central area includes the center point of the contact lens and has a constant refractive power.

[0219] According to the contact lens of the present invention, the annular area can prevent or control myopia. The diameter of the annular area can be up to 8 mm. The annular area may be provided with at least one light-blocking ring or color sample portion (extending from the peripheral area to the annular area).

[0220] According to the present invention, the peripheral region of the contact lens allows the lens to adhere to the eyeball and provides support. The peripheral region may have at least one color sample portion or at least one light-blocking ring (extending from the annular region to the peripheral region). The peripheral region is an annular area with a diameter greater than 8 mm.

[0221] According to the present invention, the color sample portion of the contact lens is mainly located in the peripheral area and may extend to the annular area (i.e., the annular area occupies a portion). It typically has an irregular pattern, which can be radial, petal-shaped, or ring-shaped, but is not limited to this. Each color sample portion has a single color, selectable from red, orange, yellow, green, blue, indigo, violet, black, white, silver, or gold. When the color sample portion is black, its maximum outer diameter is greater than 12.0 mm. If the contact lens is horizontally and vertically divided into four quadrants (A, B, C, D) with the center point as the center, at least two quadrants may have repeating patterns to form symmetry. This helps to achieve a consistent stray light reduction effect across different quadrants. The more repeating patterns in the four quadrants, the better the consistency of stray light reduction. The color sample portion can be designed with a pattern that allows for front-to-back identification, helping to provide the user with the functionality of correct wearing orientation.

[0222] According to the contact lens of the present invention, a light-blocking ring is disposed in an area outside the central area. Specifically, the light-blocking ring is mainly disposed in the annular area and may extend to the peripheral area (i.e., the peripheral area occupies a portion). The light-blocking ring is usually evenly distributed and can be monochromatic, dotted, single-ring, multi-ring, etc. The color of the light-blocking ring can be selected from red, orange, yellow, green, blue, indigo, violet, black, white, silver, or gold.

[0223] According to the contact lens of the present invention, the minimum average visible light transmittance of the light-blocking ring is less than 50%; or, the minimum average visible light transmittance of the light-blocking ring is less than 40%; or, the minimum average visible light transmittance of the light-blocking ring is less than 30%; or, the minimum average visible light transmittance of the light-blocking ring is less than 15%. The aforementioned minimum average visible light transmittance is measured as follows: any point on the light-blocking ring is selected for the average visible light transmittance measurement (range 400nm~700nm). The point with the lowest transmittance that can be measured in the light-blocking ring area can be used as the representative minimum average visible light transmittance of the light-blocking ring. Generally speaking, the minimum average visible light transmittance of a black light-blocking ring is less than 10%, and the minimum average visible light transmittance of a semi-transparent light-blocking ring is less than 50%.

[0224] According to the contact lenses of the present invention, a critical point is a point on the radius-to-diopter graph where the slope of the tangent is 0, i.e., its tangent is perpendicular to the Y-axis (D value). The D values ​​of the two points closest to the critical point must be simultaneously greater than or less than the critical point value. The number of critical points is calculated by taking an arbitrary radius line segment extending outward from the center point of the contact lens to its periphery, plotting the radius-to-diopter graph along this radius line segment, and calculating the number of critical points within the annular region of this radius line segment. These critical points may include high-critical points, medium-critical points, and low-critical points. Furthermore, critical point values ​​with the same D value are only calculated once.

[0225] In the contact lenses according to the present invention, the D value refers to the magnitude of the refractive power.

[0226] According to the contact lens of the present invention, the critical points are named in order from the center outwards. The critical point closest to the center is the first critical point (CP1), and then the second critical point, the third critical point, and so on outwards.

[0227] According to the contact lens of the present invention, the first critical point value (Power of Critical Point 1, PCP1) is the refractive power of the first critical point, the second critical point value (PCP2) is the refractive power of the second critical point, and so on.

[0228] According to the present invention, the contact lens may be a transparent lens with an average visible light transmittance greater than 92%; or, the contact lens may contain a blue dye with an average visible light transmittance greater than 83%; or, the contact lens may contain an ultraviolet absorber with an average visible light transmittance greater than 91%; or, the contact lens may contain a blue blocker with an average visible light transmittance greater than 75%.

[0229] The cycloplegic agents of this invention include, but are not limited to, atropine ((3-endo)-8-Methyl-8-azabicyclo[3.2.1]oct-3-yl tropate), tropicamide (N-Ethyl-3-hydroxy-2-phenyl-N-(4-pyridinylmethyl)propanamide), cyclopentolate (2-(Dimethylamino)ethyl (1-hydroxycyclopentyl)(phenyl)acetate), homatropine ((3-endo)-8-Methyl-8-azabicyclo[3.2.1]oct-3-yl hydroxy(phenyl)acetate), and scopolamine ((1R,2R,4S,5S,7S)-9-Methyl-3-oxa-9-azatricyclo[3.3.1.0]). [2,4]non-7-yl(2S)-3-hydroxy-2-phenylpropanoate and eucatropine (1,2,2,6-Tetramethyl-4-piperidinyl hydroxy(phenyl)acetate) and salts thereof. Cycloplegic agents, also known as mydriatics, belong to the parasympathetic nerve blocking agents, that is, non-selective M-type muscarinic receptor blockers. They paralyze and relax the ciliary muscle that controls the pupil by blocking muscarinic receptors, thereby dilating the pupil.

Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
