Battle of the Sunglasses: Polarization vs. UV Protection

Battle of the Sunglasses: Polarization vs. UV Protection

Sunglasses come in many different shapes and sizes, but you have to watch out for what protection they offer against ultraviolet radiation.

Most of you might feel that wearing sunglasses during summer is the only time you really need to wear them. But, the last time we checked, the sun rises every day—no matter the season. The sun produces damaging ultraviolet rays which affect not only the color of your skin, but may also damage your eyes. Nowadays, many sunglasses offer two options: polarized and ultraviolet protection.

They sound like the same thing, and they’re very similar, but they do have their differences. And these differences could mean the difference between keeping your eyes healthy or having them damaged by the UV light.

Polarized Sunglasses

Polarized sunglasses work in a unique way: they block out the glare from the sun while offering many kinds of UV protection. All light travels in waves: meaning that when they leave the sun some are traveling up and down, others side to side, and the rest are everything in between. When they hit the road (a horizontal plane), however, the light bounces off perpendicular to the road and switches to up and down. All these glasses have to do is make tiny filters that filter out this up and down light, and you got polarized sunglasses. However, you need to check what kind of UV protection they offer. It won’t always be the “99 to 100 percent” offered by UV Protection lenses.

UV Protection Sunglasses

Ultraviolet light can be split into two kinds of light. Kind of like how “visible light” can be split into the different colors of the rainbow. UV light is split into UVA and UVB. UVA is absorbed by the glass while UVB passes straight through and hits you. UVB is the light that penetrates your skin and does some real damage. UV protection sunglasses offer protection against both kinds of UV light and will protect your eyes from the sun.
