Description

Technical Field

[0001] This disclosure relates to the field of optics, specifically to optical lens assemblies and eyeglasses. Background Technology

[0002] Lenses that function to suppress the development of refractive errors such as myopia and hyperopia in the human eye include, for example, the lens described in known patent document CN104678572A. This patent describes a spectacle lens comprising: a first refractive region having a first refractive power; and a second refractive region having a refractive power different from the first refractive power, and having the function of focusing the image onto a location other than the retina of the eye to suppress the development of refractive errors in the eye. Near the center of the lens, the second refractive region is formed as a plurality of independent island-shaped regions, and the first refractive region is formed as a region other than the region formed as the second refractive region. Summary of the Invention

[0003] The inventors discovered that, although glasses with the function of focusing the image on a location other than the retina of the eye to suppress the development of refractive errors can suppress the development of refractive errors, they will reduce the wearer's visual acuity to some extent.

[0004] The inventors realized that, according to the principles of vision, the observer's left and right eyes see objects at different angles, and the world perceived by the brain is a mixture of the two.

[0005] The inventors ingeniously utilize the aforementioned principles to provide a novel optical lens assembly and eyeglasses. When the wearer wears these glasses, areas of reduced clarity in the left eye are compensated for by the right eye, and vice versa, creating a unique complementary relationship between the left and right eyes. Ultimately, the signals received by both eyes are integrated and fed back to the brain, allowing the brain to still obtain relatively clear and complete information about the target object.

[0150] The embodiments of the present invention will be described in detail below with reference to examples. However, those skilled in the art will understand that the following examples are only for illustrating the present invention and should not be regarded as limiting the scope of the present invention.

[0151] As used herein, “around,” “about,” or “approximately” generally means within 20 percent of a given value or range, preferably within 10 percent, and more preferably within 5 percent. The quantities given herein are approximate values, which imply the terms “around,” “approximately,” or “approximately” (where such terms are not explicitly stated).

[0152] In this invention, the term "part" means greater than 0% and less than 100%, for example, 1%-10%, 10%-20%, 20%-30%, 30%-40%, 40%-50%, 50%-60%, 60%-70%, 70%-80%, 80%-90%, or 90%-99%.

[0153] Similarly, the terms "a" or "an" are used to describe the elements and components of this disclosure. This is only for simplicity and to give the ordinary meaning of this disclosure. Unless its meaning is clearly shown otherwise, such a description should be understood to include one or at least one, and the singular also includes the plural.

[0154] It should be understood that the terms "midpoint," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the present invention and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of the present invention.

[0155] The term "at least partially overlapping" can be understood as follows: Area A and Area B at least partially overlap includes the following cases: Area A and Area B have an intersection (A∩B≠0); Area A is a subset of Area B. Area B is a subset of Area A. Area A is equal to area B (A = B). When area A and area B at least partially overlap, the proportion of the overlapping area to the total area of ​​area A is, for example, 1%-10%, 10%-20%, 20%-30%, 30%-40%, 40%-50%, 50%-60%, 60%-70%, 70%-80%, 80%-90%, or 90%-100%; and the proportion of the overlapping area to the total area of ​​area B is, for example, 1%-10%, 10%-20%, 20%-30%, 30%-40%, 40%-50%, 50%-60%, 60%-70%, 70%-80%, 80%-90%, or 90%-100%.

[0156] The term "complete overlap" can be understood as follows: if region A and region B completely overlap, it means that region A and region B are equal (A = B) or are subsets of each other.

[0157] Figure 1 (a) shows a schematic diagram of a first lens element according to some embodiments of this application; Figure 1 (b) shows a schematic diagram of a second lens element according to some embodiments of this application; Figure 1 (c) shows a schematic diagram of the overlap of a first lens element and a second lens element when they are placed parallel to each other and coaxially, according to some embodiments of this application.

[0165] When the first lens element 10 and the second lens element 20 are respectively worn on a person's left and right eyes, the beneficial effects of the optical lens group of the above embodiment are presented in the following manner:

[0166] (1) The first A region 101 of the first lens element 10 has the function of suppressing the development of refractive error in the left eye, but it weakens the visual acuity of the left eye in this region to a certain extent. However, the second B region 202 of the second lens element 20 has a lower island area 50 distribution density than the second A region 201, and the projection of the first A region 101 of the first lens element 10 onto the second lens element 20 at least partially overlaps with the second B region 202 of the second lens element 20. Based on this, it can be inferred that the second B region 202, which has at least a partial overlap with the first A region 101, has relatively high visual acuity. Simply put, it can be understood that the area where the visual acuity of the left eye is weakened is enhanced to a certain extent in the corresponding area of ​​the right eye.

[0167] (2) The second A region 201 of the second lens element 20 suppresses the development of refractive error in the left eye, but weakens the visual acuity of the right eye in this region to some extent. However, the first B region 102 of the first lens element 10 has a lower island area 50 distribution density than the first A region 101, and the projection of the second A region 201 of the second lens element 20 onto the first lens element 10 at least partially overlaps with the first B region 102 of the first lens element 10. Therefore, it can be inferred that the first B region 102, which has at least a partial overlap with the second A region 201, has relatively high visual acuity. Simply put, it can be understood that the area where the visual acuity of the right eye is weakened is enhanced to some extent in the corresponding area of ​​the left eye.

[0168] Based on the principles of vision, the observer's left and right eyes see objects at different angles, and the world perceived by the brain is a mixture of these two perspectives. Therefore, areas where clarity is reduced in the left eye are compensated for by the right eye, and vice versa, creating a unique complementary relationship between the left and right eyes. Ultimately, the signals received by both eyes are integrated and fed back to the brain, allowing the brain to still obtain relatively clear and complete information about the target object. Therefore, the lens assembly of this application, while suppressing the development of refractive errors in both eyes, cleverly utilizes the brain's ability to comprehensively utilize visual signals from both eyes, providing the wearer with relatively clear and complete information about the target object.

[0169] In some embodiments, when viewing forward, the line of sight passes through approximately the center of the lens element to view the object, thus viewing the object by a beam of light passing through multiple island-shaped regions dispersed in a manner included within the base region and a beam of light passing through the base region. As a result, the lens element has the effect of suppressing the development of myopia by visually distinguishing the image of the object formed due to the first refractive power, while simultaneously suppressing the development of myopia by the image formed in front of the retina due to the second refractive power.

[0170] In some implementations, when the eye moves, the line of sight deviates from the center and passes through the peripheral region. However, the peripheral region is an area with prescription-based refractive power (the area with primary refractive power), thus objects can be clearly distinguished very well, and the wearer experiences almost no discomfort even when the eye moves. Therefore, it is possible to demonstrate the function of inhibiting the development of refractive errors in the eye while ensuring adequate visibility and a comfortable wearing experience.

[0171] In some embodiments, in the structure of the first lens element / second lens element, the base region generally functions to focus the image onto the retina of the eye. However, for example, in the case of forming a lens element that inhibits the development of myopia, the island region is made of a material that functions to focus the image onto a point in front of the retina. Therefore, when a patient uses the lens element that inhibits the development of myopia to view an object, an image of the object is formed on the retina, and simultaneously an image is formed in front of the retina. That is, the lens element has the following function: while visually distinguishing the image of the object formed by the first refractive power, it inhibits the development of myopia by obtaining an image in front of the retina by a refractive power other than the first refractive power. The same applies to the case of hyperopia, except that in the case of hyperopia, the image is focused behind the retina of the eye by the island region.

[0172] In some implementations, the lower island region 50 distribution density in the first B region 102 compared to the first A region 101 means:

[0173] The island-shaped region distribution density in both region B 102 and region A 101 is greater than zero, but region B 102 has a lower island-shaped region distribution density than region A 101; or

[0174] The island distribution density on the first B area 102 is zero, while the island distribution density on the first A area 101 is greater than zero.

[0175] In some implementations, the lower island region 50 distribution density in the second B region 202 compared to the second A region 201 means:

[0176] The island-shaped region distribution density in both region B 202 and region A 201 is greater than zero, but region B 202 has a lower island-shaped region distribution density than region A 201; or

[0177] The island distribution density on area 202 of region B is zero, while the island distribution density on area 201 of region A is greater than zero.

[0178] In some implementations, the base zone has refractive power based on a prescription for correcting the eye's refractive errors.

[0179] In some implementations, the refractive power of the base zone is between -10.00D and 10.00D, for example, -10.00D to 0D, for example, 0D to 10.00D.

[0180] In some implementations, the refractive power of the base zone is -10.00D to -9.00D, -9.00D to -8.00D, -8.00D to -7.00D, -7.00D to -6.00D, -6.00D to -5.00D, -5.00D to -4.00D, -4.00D to -3.00D, -3.00D to -2.00D, and -2.00D to -1. .00D, -1.00D to 0.00D, 0.00D to 1.00D, 1.00D to 2.00D, 2.00D to 3.00D, 3.00D to 4.00D, 4.00D to 5.00D, 5.00D to 6.00D, 6.00D to 7.00D, 7.00D to 8.00D, 8.00D to 9.00D, 9.00D to 10.00D.

[0181] In some implementations, the refractive power of the island region is -10.00D to -9.00D, -9.00D to -8.00D, -8.00D to -7.00D, -7.00D to -6.00D, -6.00D to -5.00D, -5.00D to -4.00D, -4.00D to -3.00D, -3.00D to -2.00D, and -2.00D to -1. .00D, -1.00D to 0.00D, 0.00D to 1.00D, 1.00D to 2.00D, 2.00D to 3.00D, 3.00D to 4.00D, 4.00D to 5.00D, 5.00D to 6.00D, 6.00D to 7.00D, 7.00D to 8.00D, 8.00D to 9.00D, 9.00D to 10.00D.

[0182] In some implementations, the difference between the refractive power of the island region and the refractive power of the base region is -10.00D to -9.00D, -9.00D to -8.00D, -8.00D to -7.00D, -7.00D to -6.00D, -6.00D to -5.00D, -5.00D to -4.00D, -4.00D to -3.00D, -3.00D to -2.00D, and -2.00D. 0D to -1.00D, -1.00D to 0.00D, 0.00D to 1.00D, 1.00D to 2.00D, 2.00D to 3.00D, 3.00D to 4.00D, 4.00D to 5.00D, 5.00D to 6.00D, 6.00D to 7.00D, 7.00D to 8.00D, 8.00D to 9.00D, 9.00D to 10.00D.

[0183] In some implementations, the base region has a substantially consistent refractive power, meaning that the refractive power does not change substantially with the position of the base region surface.

[0184] In some embodiments, the base region has a refractive power that varies gradually with the position of the base region surface. A gradual variation means that the absolute value of the rate of change of refractive power along any direction of the lens element surface is greater than 0.00D / mm and less than 5.00D / mm, for example, 0.5D / mm to 1.00D / mm, 1.00D / mm to 2.00D / mm, 2.00D / mm to 3.00D / mm, 3.00D / mm to 4.00D / mm, or 4.00D to 4.50D / mm. In some embodiments, the base region has a continuously varying refractive power (gradually increasing positive refractive power or gradually decreasing negative refractive power) along the direction from the center to the edge of the lens element.

[0185] In one embodiment, the peripheral region of the base region has a more correct refractive power than the central region of the base region. In some embodiments, the peripheral region of the base region can be used to form a defocus region.

[0186] In some implementations, the island region is configured to have a refractive power abrupt change with the adjacent base region. The refractive power abrupt change constitutes the boundary between the island region and the adjacent base region.

[0187] In some implementations, a change in refractive power refers to an absolute value of the rate of change of refractive power along any direction on the surface of the lens element reaching 5.00 D / mm or more. For example, 5.00 D / mm to 6.00 D / mm, 6.00 D / mm to 7.00 D / mm, 7.00 D / mm to 8.00 D / mm, 8.00 D / mm to 9.00 D / mm, or 9.00 D / mm to 10.00 D / mm. For example, a change in refractive power of 1.00 D or more at a distance of 0.2 mm. As another example, a change in refractive power of 2.50 D or more at a distance of 0.5 mm.

[0283] Comparative Example 1

[0284] Provide a pair of glasses, the glasses configuration is as follows Figure 9 The optical lens assembly shown includes a first lens element and a second lens element.

[0285] The first lens element includes a base region 55 and an island region 50. The base region 55 has a refractive power of 0.00D, and the island region 50 has a refractive power of 3.50D.

[0287] Blank example

[0288] A pair of eyeglasses is provided, comprising an optical lens group including a first lens element and a second lens element. The first lens element consists only of a base region 55, which has zero refractive power. The second lens element consists only of a base region 55, which also has zero refractive power.

[0289] Visual clarity test:

[0290] Wearers wore glasses from Example 1, Comparative Example 1, and Comparative Example 2 respectively, and underwent visual acuity testing at a distance of 5 meters from the visual acuity chart according to the GB / T 11533-2011 standard. Wearers were instructed to observe the visual acuity chart through a designated area of ​​the lens element.

[0291] For the lens element of Example 1, the wearer is instructed to observe the eye chart through the 1X, 1Y, and 1Z zones of the lens element, respectively.

[0292] For the lens element of Example 2, the wearer is instructed to observe the eye chart through the 7X and 7Z zones of the lens element, respectively.

[0293] For the lens element of Embodiment 3, since the entire lens element is the base area, it instructs the wearer to directly observe the eye chart through the base area.

[0294] The results are as follows:

[0295] Table 1 Visual acuity records

[0296]

[0297] It can be seen from the above table:

[0298] (1) The blank example glasses do not have an island area that focuses the image on a location other than the retina of the eye to suppress the development of refractive error. The wearer's vision is not affected by the island area. Therefore, the wearer of the blank example glasses showed a visual acuity of 5.3.

[0299] (2) The glasses in Comparative Example 1 have a 7X / 9X optical zone and a 7Z / 9Z optical zone. The 7X / 9X optical zone does not have an island-shaped area that focuses the image onto a location other than the retina of the eye to suppress the development of refractive errors. Therefore, the wearer's visual acuity through this zone is 5.3. The 7Z / 9Z optical zone has an island-shaped area that focuses the image onto a location other than the retina of the eye to suppress the development of refractive errors. The wearer's visual acuity through this zone is only 5.0, which is not high.

[0300] (3) The eyeglasses of Example 1 have a first X / 2X optical zone, a first Y / 2Y optical zone, and a first Z / 2Z optical zone. The first X / 2X optical zone does not have an island-shaped area that focuses the image onto a location other than the retina of the eye to suppress the development of refractive errors. Therefore, the wearer of the blank example eyeglasses exhibits a visual acuity of 5.3. The first Z / 2Z optical zone has an island-shaped area that focuses the image onto a location other than the retina of the eye to suppress the development of refractive errors. The wearer's visual acuity through this area is only 5.0. The first A and first B areas of the first eye in the 1Y / 2Y optical zone have a unique binocular complementary structure with the second A and second B areas of the second eye. Specifically, the area of ​​the first eye weakened by the first A area is compensated for by the second B area of ​​the second eye, and the area of ​​the second eye weakened by the first B area is compensated for by the first A area of ​​the first eye. The wearer's visual acuity when observing the eye chart through the 1Y / 2Y optical zone is as high as 5.2. It can be seen that this area can both inhibit the development of refractive error of the eye and basically not lose visual acuity.

[0301] In addition, the inventors also found that the optical lens group of Embodiment 1 of this application showed results very close to those of the blank example in multiple visual function tests (especially binocular visual function tests, such as sensory fusion test and motion fusion test), indicating that the optical lens group of this application can not only suppress the development of refractive error of the eye, but also basically not reduce the wearer's visual function.

[0302] The above results demonstrate that the optical lens group, lens element, and eyeglasses of this application can provide the wearer with good visual acuity and visual function while suppressing the development of refractive errors in the eye.

[0303] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
