The present invention provides an eyeglass structure, referring to fig. 1 and 2, the eyeglass structure includes a first lens 10, a second lens 20 and a plurality of focusing columns 30, wherein the second lens 20 is disposed opposite to the first lens 10; one end of the focusing column 30 is connected with the first lens 10, and the other end is connected with the second lens 20; the first lens 10 is provided with a first correction area, the second lens 20 is provided with a second correction area corresponding to the first correction area, one end of the focusing column 30 is connected with the first correction area, and the other end is connected with the second correction area.

The lens structure of the present invention can be used for contact lenses, frame lenses, etc., and the focusing column 30 connects the first lens 10 with the second lens 20. The first lens 10 is disposed opposite to the second lens 20. When the first lens 10 is worn as a soft hydrophilic contact lens, i.e., a contact lens, the user fits over the pupil.

When the user wears normally, the projection of the first correction area and the second correction area to the pupil direction is overlapped. The first correction zone and the second correction zone provide vision correction to the user. The light beam passes through the first lens 10 and is focused by the focusing column 30 (similar to a small aperture mirror principle), so that the focal depth on the retina is increased, and a user can obviously feel that imaging is clearer when using the light beam.

It should be noted that, the first lens element 10, the second lens element 20 and the focusing post 30 are made of a material with high light transmittance, so as to avoid blocking the light beam by the focusing post 30, and avoid the ability of the user glasses to secrete dopamine substances to inhibit myopia due to the reduced brightness. The focusing beam entering the glasses is focused under the action of the focusing column 30, so that the focal depth of the imaging on the retina is increased, and the imaging on the retina is clearer after the light beam penetrates through the glasses structure.

According to the technical scheme of the invention, the first lens 10 and the second lens 20 are connected through the focusing column 30, and the first lens 10 and the second lens 20 are provided with correction areas, so that the first correction area and the second correction area are used for correction, and meanwhile, the focusing column 30 is used for enabling the light beam to pass through the glasses structure and then form a clearer image on retina, so that eyestrain is reduced, and myopia degree deterioration is inhibited.

Further, the first correction area includes a plurality of first sub-correction areas and a plurality of first sub-focal regions 12, and a plurality of first sub-correction areas and a plurality of first sub-focal regions 12 are sequentially and alternately arranged in concentric circles, wherein the center position of the concentric circles is the first sub-correction area. The second correction area comprises a plurality of second sub-correction areas 11 and a plurality of second sub-focal areas, the plurality of second sub-correction areas 11 and the plurality of second sub-focal areas are arranged in a concentric circle mode in sequence in an alternating mode, and the center position of the concentric circle is the second sub-correction area 11.

In this embodiment, the first sub-correction areas and the second sub-correction areas are alternately surrounded to form a concentric circle structure, and the circle located at the middle is the first sub-correction area. The second sub-focal zone is annular and surrounds the edge of the second sub-focal zone, the annular first sub-correction zone surrounds the edge of the second sub-focal zone, and so on. The number of the first sub-correction areas may be set to 7, and the number of the second sub-focus areas may be set to 6.

After passing through the afocal zone, the beam produces a diffuse-like effect and passes through a plurality of annularly spaced first and

second sub-afocal zones

12, 12 to produce a plurality of defocused images on the retina. It can be appreciated that the focal dispersion image does not become a significant source of visual disturbance, but is affected to some extent by photon dispersion, affecting normal use by the user. Therefore, the focusing column 30 is added in this embodiment to further improve the imaging definition, so that the reliability of the retina in normal use can be further improved and the definition can be improved on the premise of maintaining therapeutic myopic defocus on the retina.

Specifically, the first sub-correction area and the second sub-correction area 11 have the same amplification. For example, the user's myopia degree is 500 degrees, recorded as "-5D", and the magnification of the corrective structure 100 is 5D. The magnification of the first sub-focal region 12 and the second sub-focal region varies regularly along the diameter direction of the concentric circles according to a predetermined function. The preset function can be a function with a change rule such as sine, parabolic or the like. So that the power of the focal zone is in a gradual change structure. For example, a 5D magnification difference between the correction and defocus regions ensures that the resulting defocused image is optimally slowed down. For example, if the wearer's myopia is 5D, the magnification of each defocus region is between-1 and +4D in order to introduce myopic defocus.

Specifically, the number of the first sub-focal regions 12 is identical to the number of the second sub-focal regions and is set in a one-to-one correspondence manner, one end of the focusing column 30 is connected with the first sub-focal regions 12, and the other end is connected with the corresponding second sub-focal regions. I.e. in that the focusing column 30 is arranged only on the sub-focal spot. Each of the first sub-focal scattering areas 12 and the second sub-focal scattering areas are provided with a plurality of focusing columns 30, the focusing columns 30 can be in cylindrical, prismatic and other structural arrangement, the focusing columns 30 are uniformly distributed on the corresponding sub-focal scattering areas at intervals, the focusing columns 30 can be specifically arranged in a matrix distribution mode, or can also be arranged in a grid mode, and the rows and the columns are arranged in a staggered distribution mode so as to play a role in focusing. The length of the focusing post 30 may be set within a range of 0.5mm to 2mm, and the length of the focusing post 30 may be specifically adjusted according to the power of the first lens 10 or the second lens 20, or may also be adjusted according to the size of the first lens 10 or the second lens 20, so as to further improve the compatibility of the glasses structure according to the present invention.

The number of the focusing columns 30 is plural, and a plurality of the focusing columns 30 are uniformly and alternately distributed on each first sub-focal region 12 or the corresponding second sub-focal region. The ratio of the sum of the areas covered by the focusing columns 30 to the area of the sub-focal regions on the same sub-focal region is 0.5 to 0.9. I.e. the area ratio of the sub-focal spot occupied by the focusing column 30. The larger the ratio is, the larger the number of the focusing columns 30 in the current sub-focus area is, and the smaller the ratio is, the smaller the number of the focusing columns 30 in the current sub-focus area is. The number of the focusing columns 30 may be specifically adjusted according to the degree and the size of the first lens 10 or the second lens 20.

Further, the diameter of the first sub-correction area positioned at the center of the concentric circle is 3 mm-4 mm. In this embodiment, after the user wears the glasses structure, the first correcting sub-area is located at a center position of a pupil of the user. The diameter of the first sub-correction area at the middle position is set to be about 3 mm-4 mm, and the size of an adult pupil is about 5mm under normal conditions, so that the first sub-correction area at the center position of the concentric circle is slightly smaller than the size of the through hole, and the first sub-correction area can be uniformly covered on the pupil. The widths of the first sub-correcting region and the second sub-focal-dispersing region which are positioned on the edge position in a ring-shaped structure in the same way are set in the range of 0.2 mm-0.28 mm, so that the pupils are completely covered. And the magnification of each first sub-correction area is the same, so that the degree of each position is ensured to be uniform and the myopia degree of a user is ensured to be neutralized.

In the above process, the sizes of the first sub-correction zone and the second sub-focal zone, which are located in the middle position or the annular structure located in the edge position, on the concentric circle can be adjusted according to the first lens 10, the second lens 20 or the degree of myopia, so that the eyeglass structure of the present invention can be better adapted to the user, and the wearing comfort and the use experience of the user are improved, thereby improving the overall compatibility of the eyeglass structure.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
