There are two major elements to sun-glare. There is vertical glare and horizontal glare; together they create a blinding effect known as sun glare.
A polarized lens has a thin film (filter) glued or fused in-between the lens, which filters out the horizontal glare, hence eliminating a major factor to sun-glare. The effects of a polarized lens are most notable when looking at water surfaces on a bright day, driving in blinding bright conditions, reflections from a bright day with snow filled terrain etc. By eliminating horizontal glare the viewer is able to see more contrast and can actually see through the waters reflective surface. Using Nupolar and Transitions technology, Younger Optics has created the first polarized/photochromatic lens called Drivewear.
Polarized filters are also used to create a 3-demensional effect with some movies. By placing one horizontal filtered lens and one vertical filter lens in an eyewear frame, the brain attempts to bring together both viewpoints creating an illusion of a three dimensional image.
Below are some advantages and disadvantages regarding polarized lenses and some links to manufactures of polarized lenses.
