Polarized sunglasses benefits

It's a common misconception that you only need UV protection, like sunglasses and SPF, on warm, sunny days. But UV rays reflect extremely well off of cloudy skies, snow, and water. For this reason, it's important to live by the rule of thumb that if it's daytime and you're outside, you should be wearing sunglasses. Doing so can help maintain the health and clarity of your vision.

Sunglasses with a polarized lens coating have unique features that make them a great choice for active people, drivers, and more. Some of these features include glare reduction, UV protection, and more comfortable viewing.

The key behind polarized sunglasses lenses is the special chemical that's applied to the lens. The chemical blocks some — but not all — light from entering your eyes.Polarized lenses allow vertical light rays to enter your eyes so it’s possible for you to see correctly. However, horizontal light, as well as light from other angles, is filtered from entering your eyes.By blocking light from other angles, like the light that reflects off snow and water, the lenses significantly reduce glare.Glare reduction often means you’re able to see your point of focus more clearly. It also limits the blinding effect that bright light causes by bouncing off surfaces, as these light waves tend to be horizontal rather than vertical.

Polarized lenses block glare from smooth road surfaces while driving, especially when roads are wet. Make sure you can read your dashboard and other electronic displays through the lenses!

Polarized sunglasses take in vertical light, but filter out horizontal light as well as light from other angles. This effectively blocks out the hazes and glares associated with bright reflections. You'll notice the most difference on sunny days and around reflective surfaces like water and roads. Additionally, polarized sunglasses naturally lessen your need to squint in bright light conditions, which may reduce eye strain and improve visual comfort.

From an early age, almost everyone is taught that spending too much time in the sun can be bad for you. While that’s true, the single broad statement has become a kind of scientific boogeyman. Everyone’s wary about the sun, but fewer people know about the importance of UV protection and how it can help preserve your eyes and vision.
