Comparing with other lenses, we made huge progress on the lenses protection. In this product, we adopt 9 layers of coating lenses. The first layer is for anti-scratches, and strengthening the films so as to have better protection for the surface.
The second and eighth layer are the adhesive layer which could ensure the durability. The Third, fourth, sixth and seventh layer are the protective layers for absorbing ultraviolet rays in the large extent. The fifth layer is for the film filer of ultraviolet rays so as to meet your requirement for all seasons. Most importantly, the ninth layer is protective for compression and strengthening.
