All you need to know about polarized lenses when you want to buy sunglasses online.

What are polarized lenses?

Polarized lenses are lenses designed to filter the glare that creates the sunlight when it reflects in shiny surfaces (such as water or the roof of a car). This kind of glare can potentially damage our vision, that’s why polarized lenses filter it. This special filter basically blocks the intense reflected lights making your eyes feel more comfortable. How do polarized sunglasses work? As we said, polarized lenses block glare and filter the disturbing lights that can compromise our vision. However polarized lenses don’t protect from UV light. All sunglasses, at least the good ones, are designed to protect us from UV light but only some of them are polarized. Usually it is very easy to find out if your sunglasses have polarized lenses because it should be always specified in the product description. Otherwise you can choose to replace your standard sunglasses lenses with polarized ones. The first thing you need to be aware of when you buy sunglasses online is that you surely need them to protect your eyes from UV-A and UV-B rays. Low quality sunglasses can seriously damage your vision because they don’t block the UV rays. After that, you may want to understand if polarized lenses are a good choice for you because they can really improve your vision and make your eyes feel better. However polarized lenses are not the best choice for every situation.

How do you know if polarized lenses are a good choice for you?

The best thing to do it’s to try polarized lenses at least once; it’s always good to try new lenses especially if you are looking for the perfect pair of sunglasses and you haven’t found them yet. Generally speaking, polarized lenses are very good for outdoors activities and daylights and they are not very comfortable if you use LCD screens (such as the computer one) when wearing them. Usually polarized lenses are good to drive but it really depends on your personal vision condition. That is why it is always better to have your eyes checked once every one or two years and to try polarized lenses by yourself to better understand if they are a good choice for you.
