Sunny Days and Ultraviolet Rays
Now that spring has arrived we are going to see a lot more sunshine!
However, whilst we start to enjoy the sun and brighter evenings, we must remember to protect our eyes from the ultraviolet rays that come from the sun. Ultraviolet radiation is a type of light that’s invisible to the human eye, and part of the spectrum that reaches us from the sun. Excessive exposure to UV rays can result in the front surface of the eye becoming damaged, much like sunburn on the skin. Without the proper precautions, these rays can also have harmful cumulative effects that may develop over the course of years.
According to the National Eye Institute, an estimated 20% of cataract cases are caused by too much exposure to UV.
Exposure to UV without protection may also cause macular degeneration. This results from damage to the retina that destroys central vision. Additionally, wearing glasses when it’s sunny can help protect your eyes against blue light from the solar spectrum. This also increases your risk of developing macular degeneration.
Another common side effect of experiencing too much exposure to sunlight is your eyes not being able to adjust to driving at night. By wearing sunglasses, your eyes will find it easier to adapt, causing less discomfort and worry whilst driving at night.
What sunglasses should you be wearing?
The most important thing you should pay attention to when looking for sunglasses is a clear indication that they block 100% of UV rays. Additionally, if they are over-sized, they will be best to protect the whole circumference of the eye.
What to avoid?
It is best to avoid sunglasses with metal rims.
Why? Because they reflect sunlight onto the tops of your cheeks, causing them to burn. Also, it is important to remember that the sun’s rays can pass through haze and thin clouds so you should still wear your sunglasses!
