3 Things to know about polarized lenses

Polarized sunglasses designed to reduce the glare of reflected light can enhance vision for people who do water sports or drive regularly. Despite polarized lenses being trendy, many people don’t know much about them. Here are three things you should know about polarized lenses:

1. What makes polarized lenses work

Light waves travel in different directions. When reflected light bounces off a surface like water or glass, the direction of the light waves is changed. This change causes parts of your visual field to become brighter or darker, in effect called glare, making it harder to see well.

Polarized lenses have special filters that block out horizontally polarized light. This filter works because the reflections cause glare to come from below the horizontal plane, and the filter blocks out horizontally polarized light in polarized sunglasses.

2. The benefits of using polarized lenses

As mentioned earlier, polarized lenses block out horizontally polarized light that causes glare and reflection problems in vision. When this type of light is blocked, it becomes easier to see more detail. People who spend a lot of time on the water or driving in sunny conditions have reported that polarized lenses make it easier to spot fish underwater and road signs over long distances.

3. Polarized lens care

Polarized lenses are sensitive to dust and oils from your skin that can damage the polarization filter. Take care not to let those substances get on the lenses. Your polarized sunglasses may lose some of their effectiveness at blocking out reflected light.

If you want to make sure that your polarized lenses stay effective for a long time, it’s best to keep them in a case when you’re not wearing them and make sure you don’t put anything except your eyes directly in front of the lenses.
