Sun glass or light conditioners are a rage among youth and are a style statement. But these sleek glasses have a priceless benefit to accomplish. They modify incoming light to match it to your eyes with the help of latest technology. They act as protective coating from direct light like the UV rays and the reflected light in the form of glare.
They also eliminate specific frequencies of light that may blur vision or enhance contrast. Good quality sun glass are usually made of high strength, light weight, composite or metarials. Cheap sun glass which use plastic or wire frames do not often meet required optical standards and may lead to unpleasant consequences.
