Abstract
The utility model discloses a novel cataract resin lens, including main leaf and sub-leaf, main leaf and sub-leaf are circular-arc structure, and the sub-leaf is located the concave surface of main leaf and the arc bending direction of sub-leaf is opposite with the arc bending direction of main leaf. The design of the main sheet and the sub-sheets of the utility model changes the traditional structure, so that the cataract glasses have no obvious difference with the common glasses, thereby not only ensuring the luminosity and the visual field of the prior cataract glasses, but also being more beautiful.
Description
Technical Field
The utility model belongs to the resin lens field, more specifically relates to a novel cataract resin lens.
Background
Cataract is a disease that occurs in the lens inside the eye, and any clouding of the lens is referred to as cataract, but when the clouding of the lens is minor, it does not significantly affect vision and is not detected or ignored by humans and is not included in the cataract line. According to investigation, cataract is the leading cause of blindness and visual impairment in the world, and is mostly seen in the elderly over 50 years old, and the visual impairment caused by cataract is more and more increased with the increase and aging of population.
Cataract lenses generally comprise a main plate and a sub-plate, and the curvature of the sub-plate is greater than the curvature of the main plate. The arc bending directions of the sub-lens and the main lens of the existing cataract lens are consistent, so the existing cataract lens is commonly called as a hat lens, and after the cataract lens is worn, the sub-lens of the spectacles is protruded outwards and is very difficult to see.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects, providing the cataract resin lens which helps the cataract patients to correct the eyes in the postoperative transition period, ensuring the luminosity and the visual field of the prior cataract lens and being more beautiful.
In order to achieve the above object, the present invention provides a novel cataract resin lens, which comprises a main plate and a sub-plate, wherein the main plate and the sub-plate are both arc-shaped structures, and the sub-plate is located on the concave surface of the main plate and the arc bending direction of the sub-plate is opposite to the arc bending direction of the main plate.
Main leaf and sub-piece are integrated into one piece, do not have the veneer boundary, improve pleasing to the eye degree, and optical property is better than the fusion form.
The orthographic projection of the main piece and the sub-pieces is a concentric circle.
The orthographic projection surface diameter of the main piece is 55-75 mm, and the orthographic projection surface diameter of the sub piece is 30-50 mm.
The convex arc surface of the main sheet is provided with a coating layer, the coating layer can be a hardened layer or a hardened layer and a film layer, the hardened layer increases the wear resistance of the spectacle lens and increases the transmittance of a light source; the film can also be a blue light prevention film layer, an ultraviolet prevention film layer or an infrared prevention film layer, and the like, and is added with functions of blue light prevention, ultraviolet prevention or infrared prevention, and the like, and can also be simultaneously superposed with a hard layer and a functional film layer. The coating layer is arranged on the basis of cataract correction, the functionality of the lens is increased, and various requirements of a wearer are met.
Compared with the prior art, the beneficial effects of the utility model are that: the design of the main sheet and the sub-sheets of the utility model changes the traditional structure, so that the cataract glasses have no obvious difference with the common glasses, thereby not only ensuring the luminosity and the visual field of the prior cataract glasses, but also being more beautiful.

Fig. 2 is a top view of the cataract resin lens of the present invention.
Fig. 3 is a cross sectional view of a cataract resin lens of the present invention.
In the figure: 1-main tablet, 2-sub tablet.
Detailed Description
Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and specific examples.
Examples
The novel cataract resin lens shown in fig. 1-3 comprises a main plate 1 and a sub-plate 2, wherein the main plate 1 and the sub-plate 2 are both in a circular arc structure, the sub-plate 2 is positioned on the concave surface of the main plate 1, and the arc bending direction of the sub-plate 2 is opposite to the arc bending direction of the main plate 1.
Orthographic projections of the main sheet 1 and the sub-sheets 2 are concentric circles.
The orthographic projection surface diameter of the main sheet 1 is 55-75 mm, and the orthographic projection surface diameter of the sub sheet 2 is 30-50 mm.
The convex arc surface of the main sheet 1 of the utility model is provided with a hardened film coating layer, which increases the wear resistance of the spectacle lens and the transmittance of the light source; and an ultraviolet-proof film layer is also arranged to increase the ultraviolet-proof function.
While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
