22-01-25 16:01:09    By Bestsea eyewear

In a pair of eyewear, the quality of the lenses plays a crucial role in the protection of vision.

Whether it is a customer's sample or bulk, we will choose high-quality lenses. A good pair of eyewear must not be destroyed by a poor pair of lenses.

Whether it is an optical lens or a sun lens, while ensuring the quality, we will customize the function of the lens according to the customer's requirements: such as ordinary lenses, sun lens,coated lenses, anti-ultraviolet lenses, anti-blue light lenses and so on.

A pair of qualified lenses comes out of the lens factory through: material research and development, curing and hardening, molecular coating, customization, wear resistance test, to substrate inspection, hardening inspection, finished product inspection, multi-layer inspection, and level check.
