Description

Technical Field

[0001] The utility model relates to the field of optical lenses, in particular to a composite blue light-proof and yellowing-resistant high-refractive optical lens. Background Art

[0002] An optical lens is a transparent material made of optical materials such as glass or resin. It usually has one or more curved surfaces. Its main function is to refract and reflect light to achieve imaging of objects.

[0003] Existing optical lenses will gradually lose their original optical properties over time, resulting in color changes. Existing optical lenses do not have anti-blue light performance by default. Optical lenses mainly focus on the transmission, focusing and imaging quality of light, rather than specific light shielding or filtering functions. Therefore, the overall performance will decline after long-term use, and there is still room for improvement in anti-aging. Utility Model Content

[0006] Concave rounded corners are located at the rear end of the lens body to focus light and limit position within the lens body.

[0007] The rear rounded corner is arranged on the rear outer wall of the lens body, which plays a role in reducing stress and keeping the lens body light and thin.

[0008] Preferably, a concave rounded corner is provided in the center of the rear end of the lens body, a TPU thin plate is glued and fixed in the concave rounded corner, and a rear side rounded corner is provided on the rear outer wall of the lens body.

[0009] Preferably, the epoxy anti-yellowing coating is evenly covered on the surface of the TPU sheet.

[0010] Preferably, the anti-blue light coating surface is a hexagonal structure arranged in an array.
