How do Polarized Sunglass Lenses Work?

Polarized Lenses Inner Workings

Polarized lenses are normal sunglass lenses with a polarization layer fused to the lens.

How Polarized sunglass lenses are made and how polarized sunglass lenses work

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.

How to replace your upgrade or replace your sunglass lenses with polarized sunglass lenses.

The Sunglass Fix has over 30,000 sunglass lens models. We have free worldwide shipping and easy to follow video instructions to help you replace your sunglass lenses with new polarized lenses.

When Polarized Lenses Can Cause Problems?

Because polarized lenses block out glare and light at certain angles it can prevent users from seeing 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, 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 a high glare reflection off a car window. If you turn your sunglasses in a clockwise motion while looking at the glare it will get brighter and duller as the sunglasses are turned if the lenses are polarized. If the glare remains the same, you have regular sunglass lenses.


If two polarized lenses are looked through while they are parallel to each other you can see through them like regular lenses. The view is just darker. If you turn one polarized lens perpendicular to another (90 degrees) the films block all visible light as they both work to block light waves from different angles.
When looking through polarized lenses in parallel they look like regular lenses. They show the view but just darker. Polarized lenses block out entire view when turned 90 degree from each other as the films interact to block all visible light.
