Description

Optical lens group and glasses
Technical Field

Background
As a lens having a function of suppressing the development of ametropia of myopia and hyperopia in a human eye, for example, a lens described in patent document CN104678572A is known. In this patent a pair of ophthalmic lenses is described, comprising: a first refractive region having a first refractive power; and a second dioptric region having a refractive power different from the first refractive power and having a function of focusing an image on a position other than a retina of the eye to suppress development of ametropia of the eye, wherein the second dioptric region is formed as a plurality of island-shaped regions independent of each other in the vicinity of a central portion of the lens, and the first dioptric region is formed as a region other than a region formed as the second dioptric region.
SUMMERY OF THE UTILITY MODEL
The inventors found that glasses having a function of focusing an image on a position other than the retina of the eye to suppress the development of ametropia of the eye before the filing date could suppress the development of ametropia of the eye, but could reduce the visual clarity of the wearer to some extent.

In brief, it can be understood that the area of impaired visual clarity of the left eye is enhanced to some extent in the corresponding area of the right eye.
(2) The second a-zone 201 of the second lens element 20 functions to suppress the development of ametropia for the left eye, but to some extent impairs the visual clarity of that region for the right eye; however, the first B region 102 of the first lens element 10 has a lower distribution density of the island regions 50 than the first a region 101, and the projection of the second a region 201 of the second lens element 20 on the first lens element 10 at least partially coincides with the first B region 102 of the first lens element 10, whereby it is inferred that the first B region 102 having an at least partially overlapping corresponding positional relationship with the second a region 201 has a relatively high visual clarity. In brief, it can be understood that the region with impaired visual clarity for the right eye is somewhat enhanced in the corresponding region for the left eye.
According to the principle of vision generation, the left eye and the right eye of an observer respectively see a scene with an angle difference, and the world sensed by the brain is a mixed result of the two. Thus, the left eye impaired vision region is compensated for in the right eye, the right eye impaired vision region is compensated for in the left eye, and the left and right eye views are in a unique complementary relationship. Finally, the signals received by the left eye and the right eye are integrated and fed back to the brain, and the brain can still obtain relatively clear and complete target object information. Therefore, the lens assembly of the present application, while inhibiting the development of left and right eye refractive errors, skillfully utilizes the brain's ability to utilize the left and right eye visual signals in combination, providing the wearer with relatively clear and complete target object information.
In some embodiments, in a state of being viewed forward, a line of sight passes through a substantially central portion of the lens element to view the object, and therefore the object is viewed by a light beam passing through a plurality of island regions dispersedly arranged so as to be included in the base region and a light beam passing through the base region. As a result, the lens element has the following effects: the development of myopia is suppressed by an image formed in front of the retina due to the second refractive power while visually distinguishing an image of the object due to the first refractive power.
In some embodiments, the line of sight deviates from the central portion and passes through the peripheral portion as the eye moves. However, since the peripheral portion is a region having a power based on the prescription (a region having the first power), the object can be recognized very well, and the wearer has little discomfort even if the eyes move. Therefore, it is possible to exhibit a function of suppressing the progression of refractive error of the eye while ensuring sufficient visibility and good wearing feeling.
In some embodiments, in the first lens element/second lens element configuration, the base region as a whole has the function of focusing an image on the retina of the eye. However, in the case of forming a lens element that suppresses the development of myopia, for example, the island-shaped region is made of a material that has a function of focusing an image at a point in front of the retina of the eye. Therefore, when a patient views an object using a lens element that suppresses the development of myopia, an image of the object is formed on the retina while imaging the anterior square of the retina. That is, the lens element has the following functions: the progression of myopia is suppressed by an image obtained in front of the retina by refractive powers other than the first refractive power while visually recognizing an image of an object formed by the first refractive power. The same can be said for far vision except that: in the case of hyperopia, the image is focused on the posterior side of the retina of the eye by the island.
In some embodiments, the first B region 102 has a lower distribution density of island regions 50 than the first a region 101, meaning that:

In some embodiments, the base region has a substantially uniform optical power, i.e., the optical power does not substantially vary with the position of the base region surface.
In some embodiments, the base has a power that varies smoothly with changes in the position of the surface of the base, with a smooth change being a rate of change of power in either direction along the surface of the lens element of greater than 0.00D/mm and less than 5.00D/mm, e.g., 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, 4.00D to 4.50D/mm.

In one embodiment, the peripheral region of the base region has a more positive refractive power than the central region of the base region. In some embodiments, the surrounding area of the base region may be used to form the out-of-focus region.
In some embodiments, the island regions are configured such that there is an abrupt change in optical power with adjacent base regions. The abrupt refractive power transition forms the boundary between the island region and the adjacent base region.
In some embodiments, the abrupt power change is a rate of change of power in either direction along the surface of the lens element of 5.00D/mm or more in absolute terms.

For example, the change in refractive power at a distance of 0.2mm reaches 1.00D or more. For another example, the change in refractive power at a distance of 0.5mm reaches 2.50D or more.

Blank example
A pair of eyeglasses is provided that is configured with an optical lens group that includes a first lens element and a second lens element. The first lens element has only a base region 55, the base region 55 having a refractive power of 0. The second lens element has only a base region 55, the base region 55 having a refractive power of 0.
Visual clarity test:
the wearer wears the glasses of example 1, comparative example 1 and comparative example 2, respectively, and performs a vision test at a distance of 5 meters from the eye chart according to the GB/T11533-.
For the lens element of example 1, the wearer is instructed to view the chart through the 1X, 1Y, 1Z zones of the lens element, respectively.
For the lens element of example 2, the wearer was instructed to view the chart through the 7X, 7Z zones of the lens element, respectively.
For the lens element of example 3, since the lens element is entirely base-oriented, the wearer is instructed to view the chart directly through the base.
The results were as follows:
TABLE 1 Vision record values
Figure BDA0003607991800000301
From the above table, it can be seen that:
(1) the glasses of the blank do not have an island region that focuses the image on a position other than the retina of the eye to suppress the development of refractive error of the eye, the wearer's vision is not affected by the island region, and thus the wearer wearing the glasses of the blank exhibits a vision value of 5.3.
(2) The lens of comparative example 1 has a 7X/9X optical zone and a 7Z/9Z optical zone. The 7X/9X optical zone does not have an island-shaped zone that focuses the image on a location other than the retina of the eye to inhibit the development of refractive error of the eye, so the wearer exhibits a vision value of 5.3 when viewing through this zone. The 7 th Z/9 th Z has an island-shaped zone that focuses the image on a position other than the retina of the eye to suppress the development of refractive error of the eye, and the wearer has only 5.0 vision through this zone, and the vision value is not high.
(3) The lens of example 1 has the 1X/2X optical zone, the 1Y/2Y optical zone, and the 1Z/2Z optical zone. The 1X/2X optical zone does not have an island-shaped zone that focuses the image on a location other than the retina of the eye to inhibit the development of refractive error of the eye, so the wearer wearing the blank glasses exhibits a vision value of 5.3. The 1Z/2Z optic zone has an island shaped zone that focuses the image on a location other than the retina of the eye to inhibit the development of refractive error in the eye, through which zone the wearer's vision is only 5.0. The first A area and the first B area corresponding to the first eye in the 1Y/2Y optical area and the second A area and the second B area corresponding to the second eye have the structure which is complementary with the two eyes and is unique in the application, specifically, the area of the first eye weakened by the first A area is compensated in the second B area of the second eye, the area of the second eye weakened by the first B area is compensated in the first A area of the first eye, and the vision of the wearer for observing the vision chart through the 1Y/2Y optical area is up to 5.2, so that the areas can inhibit the development of the ametropia of the eyes and basically do not lose the vision value.
In addition, the inventors also found that the optical lens group of example 1 of the present application shows results very close to those of the blank examples in all of the visual function tests (particularly binocular visual function tests such as sensory fusion test and kinetic fusion test), which indicates that the optical lens group of the present application can suppress the development of ametropia of the eye and also can not substantially reduce the visual function of the wearer.
The above results demonstrate that the optical lens group, lens element and spectacles of the present application are capable of providing a wearer with good visual power values and visual functions while suppressing the development of ametropia of the eye.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: modifications can still be made to the embodiments of the invention or equivalents may be substituted for some of the features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
