What is a seamless lens? What are the advantages?

Breakthrough progress has been made in the wear resistance of lenses. In hardening and coating technology, there is a new treatment technology of special wear-resistant materials, which makes the lens wear a more transparent protective coating. The lenses treated by this technology are called "seamless" lenses.

The biggest feature of seamless lens is that the scratch resistance of lens is greatly improved. Compared with ordinary hard coated lenses, the scratch resistance of seamless lenses is improved by 2-3 times. At the same time, the surface friction coefficient of the lens is smaller, the smoothness is higher, the lens is easier to clean, the light transmittance is better, and the ultraviolet and radiation resistance are better. The use of this patented technology can avoid the problem that consumers' vision is affected by too many scratches on the lens, which leads to the decline of vision.
