Purpose, fashion and style are some of the factors which determine the colour of the lens in the sunglasses. To reduce colour distortion which is essential when driving a vehicle, it is suggested to use brown, green or grey colours. Grey is considered more neutral since they don’t boost the contrast or alter colours. But golfers prefer Yellow lens in sunglasses because of its depth perception and contrast improvements.
Models use sunglasses which have polarized lens to decrease the glare from light reflected from water or other polarized surfaces.
