Description

Technical Field

[0001] This utility model belongs to the field of spectacle lens technology, and more specifically, it relates to a polarized anti-ultraviolet spectacle lens. Background Technology

[0002] Lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After being polished, they are often assembled with eyeglass frames to form eyeglasses, used to correct the user's vision and obtain a clear field of vision.

[0003] Existing eyeglass lens designs generally include the function of blocking ultraviolet (UV) rays, aiming to protect the wearer's eyes from UV damage. However, the UV spectrum covers multiple bands, and traditional eyeglass lenses often cannot fully cover all UV bands. This may result in unsatisfactory protection, with some harmful UV rays still able to penetrate the lens and affect eye health. In addition, during long-term use, frequent cleaning and wiping, especially improper wiping methods, can easily cause numerous micro-scratches on the lens surface, reducing the lens's light transmittance and clarity, thus affecting the wearer's visual experience.

By setting the shatterproof reinforcing layer 4 made of polycarbonate and the wear-resistant layer 5 made of tin oxide, the lens can have high strength, impact resistance, and scratch resistance, which helps prevent numerous fine scratches from forming on the lens surface.
