How Do Polarized Lenses Work?
Polarized Lenses Inner Workings
Polarized lenses are normal sunglass lenses with a polarization layer fused to the lens. Normal sunglass lenses reduce the intensity of all light from all angles. The polarizing layer in polarized lenses acts like millions of microscopic mirrors. These mirrors are angled away from your eyes field of vision. When light waves hit the polarization layer at any angle that is not perpendicular to your lens it is reflected away rather than allowed through to your eye. This results in unwanted glare from roads, water and car windows being either dulled out or dramatically reduced allowing the sunglass user to see the field of vision they want. The reduction of glare provided by sunglass lenses allows users to wear their sunglasses for longer periods of time and reduces eyestrain. We also have customers that suffer from migraines claim that polarized lenses help reduce the onset of headaches.

When Polarized Lenses Can Cause Problems?
Because polarized lenses block out glare and light at certain angles it can prevent users from seeing any reflections they normally see. Reflection off of icy patches on the road or ski slopes may not show up as strong as normal. Additionally, LCD displays from certain devices such as car stereos, microwaves, mobile and computer monitors could get blocked out, especially with lower quality polarization films. We have also had feedback from some customers about the polarization interacting with polarized films in their tinted car windows.
How do I know if I have Polarized Lenses?
If your lenses are removed from your sunglasses, turn one lens 90 degrees from the other and look through both lenses at the same time. You will notice that you can't see out of the lenses. Regular sunglass lenses will just appear darker and maintain the same level of tint as they are turned. If you lenses are still in your sunglasses you can look at almost any computer screen while spinning the sunglasses around like a clock. At some angles the screen will black out and at others you will still be able to see the screen. You can also look at the glare off a car window or water. This glare should be almost unbearable without sunglasses. However, with polarized lenses you will still see the glare but should be able to view it comfortably.
