When you go outside, you may experience glare or a bright light that can make it hard to see or be comfortable. Wearing polarized sunglasses can protect your eyes and vision.
Sunlight is scattered in all directions, but when it hits a flat surface, light is reflected and becomes polarized. This means the light is more concentrated and usually travels in a horizontal direction. This intense light can cause blinding glare and reduce your visibility.
Polarized lenses can shield your vision while you’re outdoors, which may be helpful if you spend a lot of time in the sun. What are polarized lenses, and why would they be useful to you?
