How Do We Control Lens Quality?

November 10, 2025

In a pair of glasses, the quality of the lenses plays an important role in the protection of vision.


Whether it is a customer's sample or a large-scale lens, we will choose high-quality lenses. A good pair of glasses 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, 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 testing, substrate inspection, hardening inspection, finished product inspection, multi-layer inspection, and level control.

After getting the lenses from the lens factory, we will also check again by QC to ensure that the lenses attached to the frame are all good, and that the glasses are all good as a whole.
