UV420-cut lens.
—-UV+420cut technology filters out not only UVA&UVB, but also high-energy visible light(HEV light) of 400nm-420nm
—Latest reasearch has shown that blocking UV and HEV light is critical for protecting eyes against cataracts and age-related macular degeneration(AMD).
—We are still exposed to 60% of Ultraviolet rays on cloudy days and 20%-30% on rainy days. Oue blue cut lens can provide protection under all weathers.

Aspherical Design.
Aspheric eyeglass lenses allow for crisper vision than standard spheric lenses, mostly when looking in other directions than the lens optical center.
Not related to the optical quality, they may give a thinner lens, and also distort he viewer’s eyes less as seen by other people, producing better aesthetic appearance.

AR Coating.
–HC(hard coating): To protect the uncoated lenses from scratch resistance
–HMC(hard multi coated/AR coating): To protect the lens effectively from reflection, enhance functional and charity of your vision
–SHMC(super hydrophobic coating): To make the lens waterproof, antistatic, anti slip and oil resistance.
