Polarized lenses come in two different variations: .75 mm lenses and 1.1 mm lenses. While the power of polarization is the same in both types of lenses, it is a difference in the level of thickness that creates the difference between the two. However, the thickness level of the lens may not matter, depending on their use.

.75mm polarized lenses

These polarized lenses are made from thin sheets of film, and are most ideal when impact resistance is not going to be a factor. The .75mm lenses would be appropraite for most casual sports, where resistance to breakage isn’t crucial.

1.1mm polarized lenses

These polarized lenses are made with thicker sheets of film. They offer more impact resistance than .75mm polarized lenses but have the same polarizing layer. Even though 1.1 mm film is thicker, they do not offer better glare reduction or higher polarization. Typically, the added thickness makes them more expensive than the .75mm polarized lenses.

 Tinted Lenses vs. Polarized Lenses

Additionally, tinted lenses can cause objects to appear grainy, while polarized make objects more clear and distinct.
