[0002] With the advancement of science and technology and the development of society, people are paying more and more attention to vision correction and eye health. Especially in the field of eyeglasses, with the development of material science, optical technology and ergonomics, the functionality and comfort of eyeglasses have been significantly improved. Multifocal progressive eyeglasses, also known as progressive multifocal lenses, are inspired by the natural adjustment mechanism of the human eye. By setting multiple focal points on a lens, the lens has different refractive powers in different areas, thus achieving continuous clear vision at different distances from far to near. This design effectively solves the problem of traditional single-focus lenses that require frequent focal length adjustment during visual conversion, greatly reducing visual fatigue and discomfort.

[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: when wearing eyeglass lenses, they are not worn 24 hours a day. When not worn, the lenses will be placed on the table, causing friction between the lenses and the table, or the glasses will accidentally fall off, causing friction between the lenses and the ground, which can easily cause scratches and wear on the lens surface, thereby affecting the visual effect and service life of the lenses. Utility Model Content

[0029] The lens body 1 is composed of a main lens body 2 and a wear-resistant body 3, and the wear-resistant body 3 is detachably installed on the outer side of the main lens body 2. The wear-resistant body 3 includes a protective lens 33, and a reinforcement layer 31 is installed on one side of the protective lens 33. A wear-resistant coating B32 is installed on the side of the reinforcement layer 31 away from the protective lens 33. The reinforcement layer 31 and the wear-resistant coating B32 on the wear-resistant body 3 improve the wear resistance of the protective lens 33, effectively reduce the damage of the protective lens 33 caused by friction, and improve the wear resistance of the wear-resistant body 3, so as to increase the life of the wear-resistant body 3, thereby ensuring the visual effect and service life of the lens.

[0030] A wear-resistant body 3 is installed on the outer side of the main mirror body 2 as a separate wear-resistant body 3 for protecting the main mirror body 2. The wear-resistant body 3 shields the front side of the main mirror body 2 to block the friction on the main mirror body 2 and prevent the main mirror body 2 from being scratched and worn.

[0031] The main mirror body 2 includes a base mirror 23, and a wear-resistant coating A24 is installed on the outer side of the base mirror 23. The wear-resistant coating A24 improves the wear resistance of the base mirror 23 and serves as temporary wear protection when the wear-resistant body 3 is not installed, thereby improving the wear resistance of the lens and protecting the lens from wear.

[0032] An anti-blue light layer 25 is installed on the side of the base lens 23 away from the wear-resistant coating A24. The anti-blue light layer 25 can filter blue light, which helps to reduce eye fatigue. An anti-ultraviolet layer 26 is installed on the side of the anti-blue light layer 25 away from the base lens 23. An ultraviolet absorbing film 27 is installed on the side of the anti-ultraviolet layer 26 away from the anti-blue light layer 25. The cooperation between the anti-ultraviolet layer 26 and the ultraviolet absorbing film 27 can block and absorb ultraviolet rays to avoid damage to the eyes caused by ultraviolet rays.

[0033] An anti-reflection layer 28 is installed on the side of the ultraviolet absorbing film 27 away from the ultraviolet protection layer 26 , and an anti-radiation layer 29 is installed on the side of the anti-reflection layer 28 away from the ultraviolet absorbing film 27 .

[0035] The anti-blue light layer 25 is made of polycarbonate, the anti-ultraviolet layer 26 is made of polyamide, the ultraviolet absorption film 27 is made of titanium dioxide, zinc oxide and iron oxide, and the anti-radiation layer 29 is processed by a coating process.

[0036] Through the anti-blue light layer 25, the anti-ultraviolet layer 26, the ultraviolet absorption film 27 and the anti-radiation layer 29, the functions of blue light protection, ultraviolet protection and radiation protection can be achieved, and external light can be absorbed and filtered to block blue light and ultraviolet rays, thereby reducing the burden on the eyes and reducing fatigue.

[0037] During use, a wear-resistant body 3 is installed on the outer side of the main mirror body 2 as a separate wear-resistant body 3 to protect the main mirror body 2. The wear-resistant body 3 shields the front side of the main mirror body 2 to block the friction on the main mirror body 2 and prevent the main mirror body 2 from being scratched and worn. Example

[0039] Fixed connecting holes 22 are provided at the four corners of the main mirror body 2 facing outward, and magnet columns A21 are installed inside the fixed connecting holes 22. Magnet columns B35 are installed at the four corners of the protective mirror 33 facing the main mirror body 2, and the opposite surfaces of the magnet columns B35 and the magnet columns A21 are magnetically attracted to each other. The wear-resistant body 3 enters the interior of the magnet column A22 through the magnet column B35 and is magnetically adsorbed to the magnet column A21. The wear-resistant body 3 is magnetically adsorbed and installed on the outside of the main mirror body 2, thereby realizing a detachable installation between the main mirror body 2 and the wear-resistant body 3. When the main mirror body 2 is damaged, it can be directly replaced, thereby reducing the cost of later maintenance. At the same time, the magnetic adsorption installation is also convenient and quick.

[0040] A row of prying grooves 34 are provided on the top and bottom of the wear-resistant body 3, and the number of the prying grooves 34 in a row is three and they are evenly spaced. The prying grooves 34 are provided on the reinforcement layer 31 and the protective mirror 33. The reserved prying grooves 34 make it easier to pry the wear-resistant body 3 off the main mirror body 2.

[0041] During use, the magnet column B35 enters the interior of the magnet column A22 and is magnetically adsorbed with the magnet column A21, so that the wear-resistant body 3 is magnetically adsorbed and installed on the outside of the main mirror body 2.
