Polarized sunglasses can be helpful for driving too, since they reduce the glare that reflects off of cars and light-colored pavement.

Some light-sensitive people, including those who have recently had cataract surgery, can also benefit from polarized lenses.

What does polarized mean?

When a lens is polarized, it has a built-in filter that blocks bright, reflected light. This intense light is known as glare.

When glare is reduced, your eyes feel more comfortable and you can see your surroundings more clearly.

Sunlight scatters in all directions. But when it strikes flat surfaces, the reflected light tends to become polarized, meaning the reflected rays travel in a more uniform (usually horizontal) direction.

This creates an annoying, sometimes dangerous intensity of light that can reduce visibility.
