The resilient glass, which is comprised of 11-layer materials, is introduced from polarized lenses produced by an American company Polaroid. The 1st layer: Polarizing Layer, the core of polarized lenses, provides over 99% polarized light and also it can effectively absorb the reflected glare vertical to light-through axis to make lens most suitable for fishing / driving / sailing / hunting / skiing/ sports, etc. The 2nd and 3rd layers: Adhesive Layer makes the polarized lenses effectively resist incision/ bending/ cutting piece to expose it in severe environment. The 4th and 5th layers: UV Absorbing Layer makes polarized lenses effectively absorb over 99% UVA (315-380mm)and over 99% UVB (280-315 mm）. The 6th and 7th layers: Impact Resistance Layer has quality tenacity and impact resistance. The 8th and 9th layers: Polarizing Color Layer provides excellent protection to reduce the visible light transmittance. The 10th and 11th layers: Over-polished and Hard Coating Layer effectively prevents lens from scratch on the surface. The ordinary polarized sunglasses usually have 0.75mm lens, while this type of polarized sunglasses have 1.13mm thick and hard coating lens, compared to lens typed with 0.75mm, they have many advantages such as distortion resistance, higher solidity and a higher degree of wear resistance.
