About the Rays
UV (ultra-violet) rays are the bad guys, they are situated near the violet part of the visible light spectrum and they are very dangerous for your eyes. They can go through the clouds and even on an overcast day can still reach your eyes.
They are at their most dangerous from 10am to 2pm so make sure you are wearing your sunglasses during this period if you are outside.
The UV rays are split into three different types; Ultra Violet A, Ultra Violet B and Ultra Violet C.
-
UVA are the longest of the wavelengths and can penetrate through windows, there is no 100% answer as to whether or not they are harmful but we take no chances and block those out anyway.
-
UVB are more dangerous, they are the ones that can burn you and your eyes
-
UVC rays are blocked out by the earth's atmosphere and as such don’t pose a threat to your eyes.
The Lenses
We use UV400 Triacetate Cellulose polarized lenses as well as polarized REVO lenses, these are the real deal and make sure that no harmful rays reach your eyes. UV400 blocks out rays with wavelengths up to 400 nanometres which means that they block both UVA and UVB rays.
The Triacetate Cellulose is made up of 7 layers which absorb 99% of the UV rays and as well as being highly impact resistant, they cut out the strongest light and reflections from water, the road and snow effectively absorbing glare.
This means that they are perfect for any outdoor activity whether you are by the water relaxing at the beach, on the snow, fishing or if you are out driving. Polarized lenses benefits include making your view of the scenery crystal clear and with a soft tone while the anti-scratch coating ensures that if you drop them they will be scratch free!
Our Rx wood sunglasses come as standard with Cr-39 lenses which provide 100% UVA/UVB protection. They can easily be switched out for optical lenses at your local opticians.
You only have one pair of eyes and it is very important to protect them. That is why we have made sure that our lenses meet the required standards when it comes to protection from the harmful UV light.
