Overview:Everyone who works, plays or just hangs out outside needs sunglasses to protect their eyes from the sun's harmful UV rays, and shield the eyes from other hazards. Especially consumers that wear contact lenses. Glare is caused by concentrated light reflecting off surfaces like water, sand, roads, snow and ice. It reduces your ability to see clearly, and makes it nearly impossible to see into the water. Chalant Polarized sunglasses filter out glare and transmit only the light you need, providing you with increased visual clarity while reducing eyestrain. Chalant Sunglasses lenses are unique, because they contain a special filter that blocks this type of intense reflected light, reducing glare. Chalant sunglasses serve two main purposes: First, they effectively block nearly all damaging UV-rays and help to keep your eyes protected from the effects of harsh sunlight. Second, they are high quality, trendy, fashionable, and cost effective.
