Having invented polarizing lens technology, Polaroid’s press-polishing technique represents another scientific break-though in lens forming. The new collection combines designer-style with superior performance and affordable prices. Whilst most people check for 100% UV protection when buying sunglasses, many are not aware that the level of polarization is also important to health, comfort and safety. Ordinary sunglasses simply make the view darker and do not protect the eyes from vision-impeding glare.  Polaroid lenses cut out the blinding glare that causes eye irritation, eye fatigue, squinting and headaches. Together with radical press-polishing technology this means that Polaroid polarizing sunglasses provide distortion-free lens performance, high levels of scratch-resistance and unsurpassed anti-glare capability.  These lenses – which come in a range of tints including smoke, copper, tan, violet, rose or green, block out over 99% of horizontally-reflected glare - providing the highest level of glare reduction available today.
