Description
Technical Field
The invention relates to the technical field of contact lenses, in particular to a lens structure, a soft hydrophilic contact lens and a lens.
Background
Myopia is one of ametropia. When the glasses are in a condition of accommodation, parallel light rays enter the eye, which are focused in front of the retina, which results in the inability to form a clear image on the retina, known as myopia. In the state of eye adjustment relaxation, external parallel light enters the eye, and the focus of the parallel light just falls on retina to form a clear image, which is called orthoscopy; if the focal point cannot fall on the retina, it is called ametropia, i.e. ametropia.
Glasses are commonly used as an optical device to correct myopia. However, with age, the eye lens gradually hardens, thickens, and the accommodation power of the eye muscles declines, resulting in reduced zoom power. Therefore, when looking at near objects, the objects at near distances become blurred because the image is not fully focused when projected on the retina. When a myopic eye needs to view an object at a close distance, the glasses typically need to be replaced. In the prior art, the contact lens integrates the near-view lens and the presbyopic lens on the same lens, but the clear effect of wearing by a user is poor due to the limitation of the manufacturing process.

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, the first lens 10 includes a first correction area 11 and a second correction area 12, the first correction area 11 is disposed at the center of the first lens 10, and the second correction area 12 is disposed at the edge of the first lens 10; the second lens 20 is disposed opposite to the first lens 10; one end of the focusing column 30 is connected to the first correction area 11, and the other end is connected to the second lens 20.
The lens structure of the present invention may be used for contact lenses, frame lenses, etc., and the second lens 20 may be made of a common transparent lens, and the focusing column 30 connects the first lens 10 and 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 the first correcting region 11 normally, the first correcting region 11 is positioned at the center of the first lens 10, when the user uses the first correcting region 11, the sight line looks flat, the light path enters the pupil through the first correcting region 11 and focuses, and the second correcting region 12 does not influence the first correcting region 11; the first correction zone 11 serves as vision correction. 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 column 3030 focuses the light beam entering the glasses, 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.
The second correcting region 12 is located at the bottom of the first lens 10 when the user wears the device normally, and when the user uses the second correcting region 12, the line of sight is directed to the second correcting region 12, and the optical path enters the pupil through the second correcting region 12 and focuses.
In the above process, the first correcting area 11 adopts concave lenses to correct myopia, and the second correcting area 12 adopts convex lenses to correct presbyopia, so that the step of replacing glasses by users is omitted. It should be noted that, in this embodiment, the first correction area 11 and the second correction area 12 may be exchanged relatively, so as to meet the use requirements of different users and improve the product compatibility.
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 correction area 11 and the second correction area 12 are arranged at different positions on the first lens 10, so that the use requirement of switching between myopia and presbyopia is realized; meanwhile, the focusing column 30 is arranged between the first correcting region 11 and the second lens 20, so that the focusing column 30 can make the imaging of the light beam on the retina clearer after the light beam passes through the glasses structure, thereby reducing eyestrain.
Further, the first correction area 11 includes a plurality of sub-first correction areas 111 and a plurality of second correction areas 112, and the plurality of sub-first correction areas 111 and the plurality of sub-second correction areas 112 are sequentially and alternately arranged in concentric circles, and the sub-first correction areas 111 are located at the center of the concentric circles.
In this embodiment, the first sub-correction areas 111 and the second sub-correction areas 112 are alternately surrounded to form a concentric circle structure, and the circle located at the middle is the first sub-correction area 111. Around the edge of the second sub-correction zone 112, there is a ring-shaped second sub-correction zone 111 around the edge of the second sub-correction zone 112, and so on. The number of the first sub-correction areas 111 may be set to 7, and the number of the second sub-correction areas 112 may be set to 6.
Specifically, the diopter of each first sub-correction area 111 is the same, and the diopter of each second sub-correction area 112 is the same. 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 second correcting sub-area 112 is changed regularly along the diameter direction of the concentric circle according to a preset 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 second correcting sub-zone 112 is in a gradual configuration. For example, the difference in 5D magnification between the first sub-correction area 111 and the second sub-correction area 112 ensures that the resulting defocused image is optimally slowed down. If the wearer's myopia is 5D, the magnification of each defocus region is between-1 and +4D in order to introduce myopic defocus. Thereby playing the role of consistent myopia and relieving the eye fatigue of users.
The magnification of the second correcting sub-area 112 is changed regularly along the diameter direction of the concentric circle according to a preset function. After the light beam passes through the second sub-correction area 112, a diffuse reflection-like effect, i.e., a focal image, is generated. And generating a plurality of defocused images on the retina by a plurality of the first sub-correction areas 111 and the second sub-correction areas 112 which are annularly spaced apart. 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.
Further, one end of the focusing column 30 is connected to the second sub-correction area 112, the other end is connected to the second lens 20, the number of the focusing columns 30 is plural, and a plurality of the focusing columns 30 are uniformly distributed on each of the second sub-correction areas 112 at intervals. Specifically, the number of the focusing columns 30 is consistent with the number of the second sub-correction areas 112 and is set in a one-to-one correspondence manner, one end of the focusing column 30 is connected to the second sub-correction areas 112, and the other end is connected to the second lens 20. I.e. in that the focal post 30 is only arranged on the second sub-correction zone 112. Each of the second correction sub-areas 112 may be provided with a plurality of focusing columns 30, where the focusing columns 30 may be in a cylindrical, prismatic, or other structure, and a plurality of the focusing columns 30 are uniformly distributed on the corresponding second correction sub-areas 112 at intervals, and may specifically be in a matrix distribution manner, or may also be in a grid manner, and are set in a staggered distribution manner between rows and columns, so as to play a focusing role. 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.
Further, the diameter of the first sub-correction zone 111 located at the center of the concentric circles is 3mm to 4mm. In this embodiment, after the user wears the glasses structure, the first correcting sub-area 111 is located at the center of the pupil of the user. The diameter of the first sub-correction area 111 in the middle position is set to be about 3mm to 4mm, and the pupil size of an adult is about 5mm under normal conditions, so that the first sub-correction area 111 in the center position of the concentric circle is slightly smaller than the size of the through hole, so that the pupil can be uniformly covered. The widths of the first sub-correction zone 111 and the second sub-correction zone 112, which are similarly positioned at the edge positions and have a ring-shaped structure, should be set in the range of 0.2mm to 0.28mm so as to completely cover the pupil. And, the magnification of each of the first sub-correction areas 111 is the same, so as to ensure that the degree of each position is uniform and the myopia degree of the user is neutralized.
In the above process, the sizes of the first sub-correction zone 111 and the second sub-correction zone 112, both of which are located at the middle position and the first sub-correction zone 111 and the second sub-correction zone 112 of the annular structure located at 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 glasses structure of the present invention can be better adapted to the user, and the wearing comfort and the use experience of the user can be improved, thereby improving the overall compatibility of the glasses structure.

The focusing column 3030 focuses the light beam entering the glasses, 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.
