The Scientific Lens: How Does Polarization Work?

Summer may be almost over, but that doesn’t mean you need to stop worrying about UV rays. In fact, soil, water, and grass reflect less than 10% of UV radiation from the sun while fresh snow reflects 80%, dry sand reflects 15%, and seafoam reflects 25%.

Fortunately, polarized sunglasses can help to protect your eyes from harmful UV rays year-round. But what exactly does polarization mean and how does it work?

What does it mean when sunglasses are polarized?

Polarization is the act of restricting the vibration of a transverse wave, usually light. Light waves can come from the sun or an artificial light source and they vibrate outward in all directions.

When a light wave’s vibrations are aligned into one or more planed of direction, whether it’s reflected, refracted, scattered, or transmitted, it’s called polarization. Polarization can happen both naturally and artificially.

When sunglasses are polarized, this means they’ve had a special chemical applied to them during the manufacturing process that causes the eyeglass lens to polarize. The chemical that’s applied to the lenses is laminated in a vertical pattern, which causes the light waves to reorganize, blocking light and eliminating glare.

How do polarized lenses work for me?

There are many benefits to wearing polarized lenses. Not only do polarized lenses reduce glare and make it easier to see but they also reduce eye strain from long hours spent in the sun. Because of this, you may benefit from using polarized lenses if you suffer from frequent headaches due to light sensitivity.

Polarized lenses are also great for increasing contrast and visual clarity. This makes nature vacations and adventures that much more enjoyable, especially during the autumn months.

However, polarized lenses do have their limits. Liquid crystal displays, or LCDs, such as the ones used in computers and cell phones may be more difficult to see clearly when wearing these types of sunglasses.

Looking for polarized replacement lenses?

If you’re in need of polarized replacement lenses, you’re not alone. In fact, a pair of sunglasses is sat on, lost, or broken every 14 minutes in the United States.
