WHAT IS A POLARISED LENS?
Polarisation
When you see the strong reflection lights from the water, snow or whilst driving, polarised lenses can eliminate the harmful ultraviolet rays, reflection lights and deduct blue lights to make your comfortable and stop you from squinting. It can block the lights from different angles; enhancing colours to make your eyes see more clearly. This reduces eyestrain as your eyes will not tire from the squinting caused by glare.
Why Polarised?
Polarised lenses have a filter that reduces the amount of reflected light that enters the eye. This filter eliminates the horizontally reflected glare that is most noticable on water, snow, concrete and asphalt surfaces.
Normal lenses decrease the intensity of everything equally when reducing light transmittance. Polarised lenses selectively eliminate the reflection from light coming from above surfaces such as water, snow or windscreen. This is why the benefits are so useful to boaters, fishermen, an extensive variety of outdoor enthusiasts as well as divers and general use wearers.
Tinting
The color of the tint determines the parts of the light spectrum that are absorbed by the lens.
Grey Tints are great all-purpose tints that reduce the overall amount of brightness with the least amount of color distortion. Grey lenses offer good protection against glare, making them a good choice for driving and general use.
Brown Tints are also good all-purpose tints. They have added benefit of reducing more glare and have molecules that absorb higher frequency colors, such as blue, in addition to UV rays. They increase contrast and clarity.
