Sunglasses, eye health and UV400 protection | Why are sunglasses important?
Posted on November 30 2016
Did you know your sunglasses could be doing a lot more for you than reducing glare and making you look good? Here's a little info on the importance of UV400 protection lenses.
This is not my usual writing style, but sometimes you've just got to deliver the info.
What's the issue?
The primary danger the sun poses to our eyes comes in the form of Ultraviolet (UV) radiation. Most people are very aware of the harm UV rays can do to our skin, but not so aware of the damage it can cause our eyes.
Exposing the eye to UV rays can have adverse long-term and short-term effects on the eye and its vision.
What can happen?
If your eyes are exposed to excessive amounts of UV radiation over a short period of time, you are likely to experience an effect called photokeratitis.
Photokeratitis is likened to skin sunburn, but affects the cornea and conjunctiva. Symptoms would usually be noticed several hours after exposure and could include tears, pain (like having sand in your eyes), extreme sensitivity to light and red eyes. Fortunately this condition is usually temporary, but can be protected against through the use of UV400 eye protection.
Why should I be bothered?
The effects of long-term exposure to UV rays can be much more serious for the eyes. Studies have shown that exposure to small amounts of UV rays over a period of years can contribute to cataract formation, pinguecula (degeneration in the eye) and macular degeneration.
UV rays are also harmful to the sensitive skin around the eye area and we all know about the importance of of skin protection in the sunshine. It involves much more than just eye wrinkles.
With the above in mind, all of our sunglasses offer full UV400 protection, (they block all rays up to 400 nanometers). All UV rays (UV-A, UV-B and UV-C), have wavelengths below 400 nanometers. Therefore our UV400 lenses block 100% of UV rays.
So when you are choosing a new pair of sunglasses we would love them to be Faded Days, but if not please do make sure they are UV protection glasses or UV protection polarized sunglasses.
