Abstract
Description
Technical Field
[0001] This utility model relates to the field of eyeglasses design technology, and in particular to eyeglasses that eliminate binocular aberrations. Background Technology
[0002] When one or more vision problems such as myopia, hyperopia, astigmatism, presbyopia, amblyopia, or strabismus occur simultaneously, it can lead to blurred vision, double vision, loss of stereoscopic vision, and binocular single vision impairment when looking at objects normally. This can cause problems such as amblyopia, eye strain, headaches, and nausea in children.
[0003] Therefore, necessary vision correction becomes essential.
[0004] For the aforementioned visual problems and the dilemma of anisometropia, the main solutions currently focus on wearing eyeglasses, contact lenses, and refractive surgery. These methods only alleviate the size difference between the two eyes to a certain extent and involve high costs and potential uncontrollable risks.
[0005] However, for issues such as unequal refractive power between the left and right eyes that occur during binocular vision testing (e.g., unequal refractive power synchronicity, unequal refractive direction, or skewed or disordered refractive power), while there are specialized lenses on the market to address these problems, such as the Zeiss Individual 2 and Varilux X series progressive multifocal lenses with multi-point defocus, their complex design and long manufacturing cycle inadvertently drive up their market price, limiting their accessibility and widespread adoption.
[0006] Therefore, the present invention aims to develop a low-cost pair of glasses that can eliminate binocular aberrations. Utility Model Content
[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide eyeglasses that eliminate binocular aberrations. By increasing the thickness of the central area, increasing the back curvature, or decreasing the interocular distance on the basis of the basic lens, the aberrations formed between the two eyes after wearing the eyeglasses can be alleviated. Since the basic lens is already mass-produced, the eyeglasses provided by this invention are inexpensive and conducive to market promotion.
[0008] To achieve this objective, the present invention adopts the following technical solution:
[0009] This invention provides eyeglasses that eliminate binocular aberrations. The eyeglasses include a lens group, which includes a first lens and a second lens. The refractive power of the first lens is greater than that of the second lens.
[0010] Furthermore, the thickness of the central region of the first lens is greater than the thickness of the central region of the second lens, and / or the back curvature of the first lens is greater than the back curvature of the second lens, and / or the distance between the first lens and the corresponding eye on the eyeglasses is smaller than the distance between the second lens and the corresponding eye.
[0011] This invention utilizes the principle that the image size and clarity change as a visible light beam passes through glass of different thicknesses and shapes, resulting in variations in the beam's propagation direction. When prescribing glasses for users with a significant difference in refractive power between their two eyes, the refractive power of the first lens with the larger refractive power can be appropriately reduced. For example, if the difference in refractive power is less than or equal to 3.00D, there is no need to reduce the refractive power of the first lens. Furthermore, during lens fabrication, the thickness or backward curvature of the central area of the first lens is increased. This allows for clear imaging even when the difference in refractive power between the two eyes is within 3.00D. After wearing the glasses, the aberrations in the position and size of the images seen by the two eyes are significantly alleviated, resulting in a significant improvement in user comfort.
[0012] Another design is to ensure that the refractive power of the first lens, which has a larger refractive power, still corresponds to the corresponding eye. In this way, the difference in refractive power between the first and second lenses is larger. By designing the eyeglasses so that the interocular distance of the first lens is smaller than that of the second lens, aberrations can be greatly reduced on the basis of clear imaging, which has broad application prospects.
[0013] The present invention can increase the curvature of the upper or lower arc backward curvature of the first lens, or increase the curvature of both the upper and lower arc backward curvature at the same time.
[0014] It is worth noting that when the difference in refractive power between the user's two eyes is set to ΔD, the difference in refractive power between the first lens and the second lens can be kept at ΔD, and the aberration can be reduced by decreasing the interocular distance of the first lens.
[0015] When the difference in refractive power between the user's two eyes is ΔD, and ΔD is greater than or equal to 3.00D, the first lens has a refractive power 3.00D greater than the second lens, and the central region thickness of the first lens is greater than that of the second lens, and / or the posterior curvature of the first lens is greater than that of the second lens. When ΔD is less than 3.00D, the first lens has a refractive power D greater than the second lens, and the central region thickness of the first lens is greater than that of the second lens, and / or the posterior curvature of the first lens is greater than that of the second lens.
[0016] Preferably, the thickness of the central region of the first lens is 0.3 to 1.0 mm thicker than the thickness of the central region of the second lens. For example, it can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1.0 mm, but is not limited to the listed values. Other unlisted values within this range are also applicable.
[0017] In this invention, the specific difference in thickness between the central regions of the first lens and the second lens depends on the refractive power of both eyes. Specifically, when the difference in refractive power between the two eyes is ΔD, the change in the thickness of the central region of the first lens compared to the second lens is determined by the effective refractive index of the semi-finished lens corresponding to the actual refractive power value. Generally, a larger actual refractive power value (negative for myopia, positive for hyperopia) corresponds to a higher refractive index. Based on the parameters of the selected semi-finished lens (including its refractive index, semi-finished thickness, curvature, diameter, etc.) and the required refractive value D, the necessary increase in central thickness is automatically obtained using a self-developed controllable central thickness software.
[0018] Preferably, the difference between the refractive power of the first lens and the refractive power of the second lens is less than or equal to 3.00D, and the thickness of the central region of the first lens is 0.3 to 0.5 mm thicker than the thickness of the central region of the second lens, for example, it can be 0.3 mm, 0.33 mm, 0.35 mm, 0.37 mm, 0.39 mm, 0.42 mm, 0.44 mm, 0.46 mm, 0.48 mm or 0.5 mm, but is not limited to the listed values. Other unlisted values within this range are also applicable.
[0019] Preferably, the difference between the refractive power of the first lens and the refractive power of the second lens is greater than 3.00D, and the thickness of the central region of the first lens is 0.5 to 1.0 mm thicker than the thickness of the central region of the second lens. For example, it can be 0.5 mm, 0.56 mm, 0.62 mm, 0.67 mm, 0.73 mm, 0.78 mm, 0.84 mm, 0.89 mm, 0.95 mm, or 1.0 mm, but is not limited to the listed values. Other unlisted values within this range are also applicable.
[0020] Preferably, the back curvature of the first lens is 50 to 150 degrees greater than that of the second lens. For example, it can be 50, 55, 60, 65, 70, 75, 80, 90, 100, 110, 120, 130, 140 or 150 degrees of curvature, but is not limited to the listed values. Other unlisted values within this range are also applicable.
[0021] In this invention, the exact difference in back curvature between the first and second lenses depends on the refractive power of both eyes. Specifically, when the difference in refractive power between the two eyes is ΔD, the change in back curvature between the first and second lenses is determined by the effective refractive index of the semi-finished lens corresponding to its actual refractive power value. Generally, a higher actual refractive power value (negative for myopia, positive for hyperopia) corresponds to a higher refractive index. Based on the parameters of the selected semi-finished lens (including its refractive index, thickness, back and front curvature, diameter, etc.) and the required refractive value D, the necessary increase in back curvature is automatically obtained using a self-developed controllable curvature controllable lens software.
[0022] Preferably, the difference between the refractive power of the first lens and the refractive power of the second lens is less than or equal to 3.00D, and the back curvature of the first lens is 50 to 100 degrees greater than that of the second lens. For example, it can be 50, 55, 60, 65, 70, 75, 80, 90, 95 or 100 degrees of curvature, but is not limited to the listed values. Other unlisted values within this range are also applicable.
[0023] Preferably, the difference between the refractive power of the first lens and the refractive power of the second lens is greater than 3.00D, and the back curvature of the first lens is 75 to 150 degrees greater than that of the second lens. For example, it can be 75, 80, 85, 90, 100, 105, 110, 120, 130, 135, 140, 145 or 150 degrees of curvature, but is not limited to the listed values. Other unlisted values within this range are also applicable.
[0024] Preferably, the distance between the first lens on the eyeglasses and the corresponding eye is 0.01 to 5 mm smaller than the distance between the second lens and the corresponding eye. For example, it can be 0.01 mm, 0.57 mm, 1.12 mm, 1.68 mm, 2.23 mm, 2.79 mm, 3.34 mm, 3.9 mm, 4.45 mm, or 5 mm, but is not limited to the listed values. Other unlisted values within this range are also applicable.
[0025] It is worth noting that when the difference in refractive power between a user's two eyes is ΔD, but the increase in the center thickness of the lens is less than 0.3mm or the increase in curvature is no more than 50 degrees, the difference in refractive power between the first lens and the second lens can be maintained at ΔD. The lens-to-eye distance adjustment software developed by the company can be used to change the lens-to-eye distance of the first lens to achieve the effect of reducing aberration.
[0026] The eyeglasses provided by this utility model are suitable for various ordinary resin lenses. In terms of refractive index, they include 1.56, 1.60, 1.67, 1.74, etc. In terms of material, they include acrylic and polyurethane series, and have broad application prospects.
[0027] It's worth noting that due to the inherent limitations of glass (such as fragility and weight), high-definition optical resin materials are used as the transmission medium. Through the standard manufacturing process of optical resin lenses, suitable patterns can be designed at any time according to different consumer needs. Combined with CNC automated equipment, lenses that produce appropriate images to meet the required anisometropia can be obtained. The process is short, and other special functions (such as photochromic or tinted lenses) can be added. Since resin lenses are already mass-produced, the per-unit cost is very low, thus perfectly achieving the marketization and cost reduction of this special lens.
[0028] As those skilled in the art will know, the eyeglasses also include a frame and temples for mounting the lens assembly, the temples being connected to the frame and used for mounting on the ears.
[0029] This invention does not impose any special restrictions on other specific structures in the above-mentioned eyeglasses. Any specific structure known to those skilled in the art that can be used for eyeglasses can be adopted, and adjustments can be made according to the actual situation.
[0030] The backbend referred to in this utility model refers to the curvature of the region of the first and second lenses after aberration elimination following CNC machining. The region refers to the central area of the first and second lenses and the transition area adjacent to the central area.
[0031] The so-called "region" in this utility model refers to a region with a radius of 25-30 mm centered on the geometric centers of the first and second lenses, and a region with an outer length of 25-35 mm around the circumference of the circle.
[0032] Preferably, when the first lens is a positive lens (for farsightedness), the thickness gradually decreases from the central region to the peripheral region, and the gradual decrease in thickness varies from 0.3 to 5.0 mm, for example, 0.3 mm, 0.4 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.2 mm, 3.5 mm, 4.0 mm, 4.2 mm, 4.5 mm, or 5.0 mm, etc.; when the first lens is a negative lens (for nearsightedness), the thickness gradually decreases from the peripheral region to the central region, and the gradual decrease in thickness varies from 0.1 to 4.0 mm, for example, 0.1 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.5 mm, 3.0 mm, 3.2 mm, 3.5 mm, or 4.0 mm, etc.
[0033] In this invention, there is no special limitation on the left and right eyes corresponding to the first and second lenses. The first lens corresponds to the eye with higher refractive power, and the second lens corresponds to the eye with lower refractive power.
[0034] Compared with the prior art, the present invention has at least the following beneficial effects:
[0035] The binocular aberration-eliminating glasses provided by this utility model can alleviate binocular aberrations by improving the design of the first lens with a large refractive power based on the existing lens substrate, thereby improving wearer comfort while ensuring clarity. More importantly, the solution provided by this utility model can directly and simply process and modify the mass-produced substrate lenses, which is time-saving, low-cost, conducive to industrial production, and has broad application prospects.

[0047] Example 1
[0048] The user's refractive error test results are as follows: R (right eye): -6.00D, L (left eye): -10.00D. When wearing normal finished lenses, each eye can form a clear image. However, due to the difference in refractive error between the two eyes being 4.00D, which exceeds the range of 3.00D, two images of different sizes will appear when both eyes are looking at an object at the same time. The aberration is large, which can easily cause dizziness and blurred vision after wearing the lenses, resulting in poor comfort.
[0049] This embodiment provides a pair of glasses that eliminates binocular aberration. Specifically, the glasses include a lens assembly, see [link to documentation]. Figure 1 The lens group includes a first lens 11 and a second lens 12; the first lens 11 corresponds to the left eye, and the second lens 12 corresponds to the right eye. The first lens 11 and the second lens 12 are both made from two semi-finished lenses with the same refractive index (1.67) and the same curvature of 200 degrees (the corresponding front and back curvature, semi-finished thickness, and diameter are also measured simultaneously). The second lens 12 is made according to -6.00D, while the first lens 11 is made according to -9.00D. At the same time, the thickness of the central area of the lens is increased by 0.8mm. The first lens 11 and the second lens 12 are both made by CNC machine tools.
[0050] The light transmission diagram of the lens assembly in the eyeglasses provided in this embodiment is as follows: Figure 2 As shown in the figure, the glasses provided in this embodiment provide clear images with no aberrations between the left and right eyes after being worn by the user, and offer high comfort. The images before and after wearing are shown in the figures below. Figures 3-4 As shown, from Figures 3-4 As can be seen, this embodiment solves the aberration problem and produces clear images.
[0051] Example 2
[0052] The user's refractive error test results are as follows: R (right eye): +6.00D, L (left eye): +9.50D. When wearing normal finished lenses, each eye can form a clear image. However, because the difference in refractive error between the two eyes is 3.50D, which exceeds the range of 3.00D, two images of different sizes will appear when both eyes look at an object at the same time. The aberration is large, which can easily cause dizziness and blurred vision after wearing the lenses, resulting in poor comfort.
[0053] This embodiment provides a pair of glasses that eliminates binocular aberration. Specifically, the glasses include a lens assembly, such as... Figure 5 As shown, the lens group includes a first lens 11 and a second lens 12; the first lens 11 corresponds to the left eye, and the second lens 12 corresponds to the right eye. The first lens 11 and the second lens 12 are both made from two semi-finished lenses with the same refractive index (1.60) and a conventional 600° curvature (the corresponding front and rear curvature, semi-finished thickness, and diameter are also measured simultaneously). The second lens 12 is made according to +6.00D, while the first lens 11 is made according to +9.00D. At the same time, the front and rear curvatures of the second lens 12 are both increased by 75°. The first lens 11 and the second lens 12 are both made using CNC machine tools.
[0054] The light transmission diagram of the lens assembly in the eyeglasses provided in this embodiment is as follows: Figure 6 As shown, the glasses provided in this embodiment provide clear images and no aberrations between the left and right eyes when worn by the user, resulting in high comfort.
[0055] Example 3
[0056] The user's refractive error test results are as follows: R (right eye): -12.00D, L (left eye): -8.00D. When wearing normal finished lenses, each eye can form a clear image. However, because the difference in refractive error between the two eyes is 4.00D, which exceeds the range of 3.00D, two images of different sizes will appear when both eyes look at an object at the same time. The aberration is large, which can easily cause dizziness and blurred vision after wearing the lenses, resulting in poor comfort.
[0057] This embodiment provides a pair of glasses that eliminates binocular aberration. Specifically, the glasses include a lens assembly, such as... Figure 7As shown, the lens assembly includes a first lens 11 and a second lens 12. The first lens 11 corresponds to the right eye, and the second lens 12 corresponds to the left eye. Both the first lens 11 and the second lens 12 are produced using two semi-finished lenses with the same refractive index (1.67 or 1.74) and a standard 600° curvature (the corresponding front and rear curvature, semi-finished thickness, and diameter are also measured simultaneously). Both the first lens 11 and the second lens 12 are manufactured using CNC machine tools, resulting in lenses with diopter values of 12.00D and 8.00D, respectively. The distance between the first lens 11 and its corresponding eye 100 is 0.4mm smaller than the distance between the second lens 12 and its corresponding eye 100.
[0058] The images from both eyes in this invention can be perfectly "overlapped" together and are clear, making the wearer comfortable.
[0059] In contrast, if the first and second lenses in the above embodiment 3 are placed at the same distance between the eyes or simply placed on the same plane at equal distances, clear imaging is achieved for a single eye. However, when the light from both eyes overlaps, some degree of ghosting will occur.
[0060] Example 4
[0061] The user's refractive error test results are: R (right eye): -7.50D, L (left eye): -4.00D. When wearing normal finished lenses, each eye can form a clear image, but the difference in refractive power between the two eyes is greater than 3.00D. When both eyes look at an object at the same time, two images of different sizes will appear, resulting in a large aberration. Wearing these lenses can easily cause dizziness and blurred vision, and the comfort level is poor. In addition, the user's work environment requires additional lenses with photochromic protection function.
[0062] This embodiment provides a pair of glasses to eliminate binocular aberrations. Specifically, the glasses include a lens group, which includes a first lens and a second lens. Both the first and second lenses are 1.60 conventional bonded photochromic lenses (polyurethane material) or conventional spin-coated photochromic lenses (polyurethane or acrylic material). The first lens corresponds to the right eye, and the second lens corresponds to the left eye. The second lens is manufactured to -4.00D, while the first lens is manufactured to -6.50D. The thickness of the first lens in the central region is increased by 0.73mm. Both the first and second lenses are manufactured using CNC machine tools.
[0063] The glasses provided in this embodiment provide clear images without aberrations between the left and right eyes, offer high comfort, and meet the user's special usage requirements.
[0064] Furthermore, if a user has a high refractive power, the high-power lenses (1.67 and 1.74 refractive index semi-finished products) can be replaced with resin materials by special glass materials (1.80 and 1.90 refractive index high-priced special glass), demonstrating its economic effectiveness.
[0065] The lenses in the above embodiments of this utility model can also be replaced with anti-blue light, spherical or aspherical semi-finished lenses, all of which can be mass-produced in a conventional manner and are low in cost.
[0066] Comparative Example 1
[0067] The user's refractive error measurement results are: R: -10.00D, L: -6.00D.
[0068] This model directly uses lenses with the corresponding refractive index for correction, allowing each eye to obtain a normal and clear image individually. Wearing them directly results in overlapping clear images, requiring the eyes to self-adjust for a longer period of time. Even if using high refractive power with low prescription can alleviate discomfort in both eyes to some extent, the refractive eye is constantly in a state of fatigue. Over time, this will further aggravate the refractive error and anisometropia in both eyes.
[0069] Comparative Example 2
[0070] The user's refractive error measurement results are: R: +9.00D, L: +6.00D.
[0071] This comparison model directly uses lenses with the corresponding refractive index for correction. The visual acuity of each eye is normal and clear when viewed separately. However, when the images are superimposed, the eyes need to self-adjust for a longer period of time. Over time, this will further increase the refractive power and anisometropia of both eyes.
[0072] Comparative Example 3
[0073] The user's refractive error test results are: R: -1.00D, L: -6.25D. This means that there is a different phase difference between the left and right eyes.
[0074] In terms of refractive power, this comparison can be made by randomly selecting lenses of 1.56, 1.60, 1.67, or 1.74 and aligning them with their respective phase angles; the corresponding eyes will all obtain clear images.
[0075] However, in this comparison, because the anisometropia between the two eyes is -5.25D, objects at the same position are not imaged at the same point on the retina (one is in front and the other is behind). The intuitive reaction is that objects appear blurry. With prolonged use, the refractive power and anisometropia may further increase.
[0076] Comparative Example 4
[0077] Taking the refractive power of the left and right eyes in Comparative Example 2 (R: +9.00D, L: +6.00D) as an example, to simultaneously achieve refractive correction and aberration elimination, multifocal semi-finished lenses (including multi-point defocus, dual-point defocus, progressive multifocal, etc.) and other specialized lenses with a refractive index of 1.67 or 1.60 can be considered. However, the drawback is that the market price of this type of lens is more than 20 times that of conventional lenses, and the higher the refractive index, the more expensive it is, far exceeding the acceptable range for the average person. Furthermore, these specialized lenses have certain usage conditions and a 3-7 day proficiency period for the wearer.
[0078] Comparative Example 5
[0079] The user's refractive error measurement results are: R: +9.00D, L: +6.50D. The user also needs to meet the requirement of color change.
[0080] In order to ensure concentrated light projection, this comparative example uses photochromic multifocal lenses, which are made separately according to their refractive power. The difference from Example 4 is that the first lens is made directly according to +9.00D.
[0081] The single image obtained in this comparative example is clear. However, since it is a professional lens, it is necessary to have a comprehensive visual function examination by a professional institution before wearing it. Otherwise, it may easily cause discomfort in both eyes. As the discomfort continues, the eyeball may become darker by +0.25D or +0.50D. At the same time, phase difference will occur due to long-term fatigue of the lens, and the control will not be effective. According to Comparative Example 4, the market price of the composite special lens in this comparative example is no less than 20 to 25 times that of the conventional lens.
[0082] This utility model has been described in detail through the above embodiments. However, this utility model is not limited to the above detailed features, that is, it does not mean that this utility model must rely on the above detailed features to be implemented. Those skilled in the art should understand that any improvements to this utility model, equivalent substitutions for the selected technical features, additions of auxiliary technical features, and selection of specific methods, etc., all fall within the protection scope and disclosure scope of this utility model.
