Sunglasses and hat for protection against UV rays.
9th November 2017

Earlier last month we posted an article about protecting your eyes from the sun’s UV rays. But how do you choose the right protection for your eyes against UV rays? We would like to provide you with some tips so that you can pick out the protection that your eyes need.

When it comes to protecting your eyes against UV rays there are two important things that you need to know:

1. Know the dangers of UV rays.

2. Know what kind of eye and head protection you need against UV rays (Wear proper eye protection and hats that block UV rays).

UV rays don’t just come from directly from the sun. It also gets reflected off the ground and off of bright surfaces like water, snow or sand.


Choosing UV protection

A brimmed hat or cap (the wider the better) will block about 50% of UV rays.
A hat or cap can also help you to limit UV rays that usually hit the eyes from above or around the glasses.

Eyewear like: prescription & non-prescription glasses, contact lenses, and lens implants should do a good job of absorbing UV-A and UV-B rays.
With everyday eyewear, there should are several options like UV-blocking lens materials, coatings and photochromic lenses (see image below). UV protecting eyewear usually does not cost a lot of money and it does not deny you of seeing clearly.

Sunglasses have two main purposes: light filtering and UV protection.

Choose sunglasses that have:

– Reduce glare
– Filter out 99-100% of UV rays
– Protect your eyes
– Are comfortable to wear
– Do not distort colors

When you are going to the beach or to areas where there is a lot snow, you should wear sunglasses with a darker tint to block more light. In areas with snow you should wear special snow sunglasses or ski goggles. As mentioned before, the UV reflection off the water and snow is usually intensified and hence the risk of eye damage from the sun is bigger.

When buying sunglasses always make sure there is a tag or label attached stating the amount of UV radiation that is being blocked. Always check and read the tags or labels carefully and make sure that the sunglasses block 99 to 100% of UV-A and UV-B rays.
