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. Visionary Supplies would like to introduce Sheer Vision. Sheer Vision is 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...Sheer Vision is an enhanced polycarbonate plastic lens material with a unique coating applied to both the front and back 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 polycarbonate material blocks the harmful UV light rays coming from the sun. These UV lights are normally very dangerous to the retina. Not only do Sheer Vision 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. ALSO AVAILABLE: You can also purchase yellow lenses with an AR coating or a light Polarized grey lens. The yellow lenses brighten things up and are excellent for hazy and foggy weather, but are not great for the headlights coming at you. The polarized grey lenses work great for the bright lights coming at you in highway traffic, but are a little dark for your back roads.
