Importance of UV Protection

Posted by Aubrey Tam on

Don't let the clouds fool you - no matter it is sunny or cloudy, we are exposed to ultraviolet (UV) radiation from the sun every dayEver wonder what is the impact of UV radiation and why is it so vital to keep your eyes protected?

Here's the answer...

① What are UV Rays

There are 3 types of ultraviolet radiation—UVA, UVB, and UVC. UVC is seldom heard as it is absorbed by the earth's ozone layer, making its threat minimal to nonexistent. UVA is the most abundant source of solar radiation and penetrates beyond the top layer of skin, while UVB rays penetrate less deeply into skin. Both UV-A and UV-B can cause short and long term damage to your eyes and your vision respectively.

The fact is, with the right protective glasses, 99-100% of the harmful UV rays can be blocked from reaching your eyes and causing damage. While wearing a hat can only cut the amount of UV rays that reach the eyes in half.

 Impact & Damages of UV Rays 

Without UV-protected sunglasses, your eyes may result in various symptoms!

Just like sunburn to your skin, short exposure to UV radiation can cause huge damage to your eyes. Short terms symptoms are, for example, red and puffy eyes, or feeling gritty as if you have sand in them. You may also suffer from excessive tearing.

Though these symptoms are temporary, if your eyes are exposed to long-term solar radiation, you are building a higher risks of getting eye diseases later in life, such as cataracts, damage to the cornea and retina, eye cancer.


③ What Do We Do?

Fact is, UV damage is cumulative through your lifetime, and around 1/4 of UV damage to your eyes occurs before the age of 20. Therefore it is recommend to protect your eyes at an early age, as you are not able to reverse the damage.

So, before your next outdoor activity, be sure to get well enough protection for your eyes. Get a pair of shades with guaranteed "100% UVA / UVB Protection" and have fun in the sun!
