[0025] The chamfer radius of chamfered portion 6 ranges between 0.2mm to 2mm, and the chamfer width of chamfered portion 6 ranges between 1mm to 2mm, and the chamfer helps to remove sharp corners, reduce damage to the lens during transportation, storage and use, help to disperse larger stress, especially in the case of larger lens and lower optical precision requirement, can improve the anti-breaking capacity of the lens, and reasonable chamfer radius and chamfer width selection can not only improve the mechanical strength and durability of the lens, but also ensure the stability of the optical performance.

[0026] The concave curvature of the inner concave part 7 is between 2mm and 10mm, and the inner concave part 7 is annularly distributed. In the design of the optical lens, the inner concave structure helps to change the incident angle and reflection path of light, which can effectively reduce the reflection of the lens surface, reduce glare, and improve visual comfort. The annular inner concave design can effectively disperse stress, improve impact resistance, and help reduce reflection and glare. However, when designing, the effect of the inner concave shape on the optical performance must be fully considered, and the curvature range must be adjusted according to the specific application of the lens to ensure the best performance of the optical effect.

The anti-skid lines uniformly distributed on the inner wall of the mounting groove 4 help to improve the friction between the mounting groove and the lens body. The anti-skid lines can form a small frictional resistance between the surfaces of the lens body 1 and the mounting groove 4, which helps to prevent unnecessary movement of the lens body 1 and ensures that it does not displace in the fixed position, enhancing the overall safety and reliability.

[0028] The diameter of the retaining ring 5 is 1-3mm larger than that of the mounting groove 4, and the retaining ring 5 is tightly fitted with the lens body 1.

Through the bonding effect of the adhesive, the fixing force between the two can be strengthened, so that the magnetic ring 3 will not easily fall off. Through the joint action of the adhesive and the groove, the durability of the frame 2 and the magnetic ring 3 can be improved, ensuring that the adhesive will not fail due to external environment or mechanical impact during long-term use.
