Anti-reflective eyeglass coating.
Many eye care professionals strongly recommend glasses with an anti-reflective (AR) coating. This ultra-thin film, made from zircon and silicon, reduces internal reflections in the lenses.
Unlike sunglasses or self-darkening lenses, which block some light, AR-coated glasses actually transmit more light – about 8 percent more. This improves vision at night and helps distinguish fine details during the day. Highway patrol troopers have reported better night and day vision and reduced nighttime glare with AR-coated lenses.
Sigma Driving Sunglasses are a line of superior quality, anti-glare filter glasses for the night driving eyewear market. Our company devoted the necessary time and resources to developing an Anti-Glare Eyewear product that not only does the job, but is the most comfortable and stylish to wear. Here’s how we did it…Sigma Sunglasses is an enhanced plastic lens material with a unique coating applied to the front surfaces. The coating creates a unique physical characteristic on the lens that resembles an oily residue or a drop of water in a puddle. This unique coating eliminates the glare while the enhanced plastic material blocks the harmful UV light rays coming from the sun. These UV lights are normally very dangerous to the retina. Not only do Sigma Sunglasses products reduce glare and UV light intake, but our state of the art lenses ALSO reduce headaches that usually are caused by prolonged, unprotected exposure to the persistent onslaught of harmful rays.
