When you are looking to buy a pair of sunglasses, you might be wondering what the difference is between polarized and non-polarized sunglasses. Here we will look at polarized vs. non-polarized sunglasses and which ones are best depending on what you will be wearing sunglasses for.
Polarized sunglasses have a number of advantages over non-polarized sunglasses. Firstly, polarized sunglasses provide 100 UV protection that protects the eyes from damage and secondly they provide protection against horizontal glare, providing clearer vision.
Non-polarized sunglasses, on the other hand, have a dark shade and are able to reduce the intensity of light, but they are not able to counteract the effects of horizontal polarization.
Polarized sunglasses improve visibility and provide better protection, but they can reduce the visibility of images that are created on LCD screens.
About Light and Polarized Sunglasses
The brightness and glare that we experience from the sun can make it difficult for us to drive, ride a bicycle or just walk around unless we are wearing the correct eye protection. Glare occurs when the amount of light that is in our field of vision is more than the amount that our eyes are used to. You are only able to get effective protection from glare with polarized sunglasses.
The Dangers of UV Rays and Glares
Light is made up of waves and they travel in all directions. Vertical rays are good for the eyes, but horizontal rays can cause damage. Glare is created when concentrated light bounces off horizontal surfaces like sand, car windshields and snow, which can hurt the eyes. This is why it is best to get polarized sunglasses. You are able to get polarized sunglasses for men and women and kids polarized sunglasses like the ones at Sunbelt Optics.
Normal sunglasses are able to filter all light whether it is vertical or horizontal, but it reduces visual sharpness. Exposure to UV rays over the long term can be dangerous and many of us think that just because we wear any old sunglasses we are protected from these rays, but in fact, sunglasses widen the pupils, which allow in more UV rays. Sunglasses with 100 UV protection are the best polarized sunglasses as you are able to avoid damage to the eyes.
Polarized sunglasses offer 100 UV protection. Regular sunglasses filter out all light, whereas polarized sunglasses allow more vertical light to enter, which will then improve visibility whilst blocking horizontal light.

Polarized sunglasses reduce the visibility of LED and LCD screens like cell phones and GPS. This can be an issue if you are a pilot or a boater where you will need to see and read LCD screens.
Who Should Wear Polarized Sunglasses
Polarized sunglasses are ideal for those that fish, ride a bicycle or take part in other sports. Polarized sunglasses for driving are also a good idea because they are able to reduce the glare from the road and other cars.
Polarized sunglasses are beneficial in a number of circumstances, but not in all. They are most suited to those that spend a lot of time outdoors as they protect the eyes from UV as well as provide better vision.
