About Joopin Vintage Round Sunglasses For Women Retro
REAL UV400 PROTECTION--Joopin lenses are engineered to block 100% of all harmful blue light up to 400 nanometers including UVA(320-400 nm),UVB(280-320 nm)and UVC(100-280 nm). TAC POLARIZED LENS-TAC lens includes 8 layers. The 1st layer is polarization layer. The 2nd and 3rd layers are adhesive layers to enable durability. The 4th and 5th layers are UV protection layers to absorb UV light. The 6th and 7th layers are shatterproof layers.The 8th layers are anti reflective green coating. How Do Polarized Lenses Work? Light reflected from surfaces such as a flat road or smooth water generally is horizontally polarized. This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare. Polarized sunglasses reduce glare reflected off of roads, bodies of water, snow, and other horizontal surfaces. Polarized sunglasses cut glare and haze so your eyes are more comfortable and you can see better.
