Our eyes are sensitive organs and it is imperative that we protect them. While most people understand how physical or chemical harm could befall our eyes, a surprisingly large number of people don’t realize that one of the greatest threats to our eyes is the Sun.
The sun emits a constant stream of ultraviolet light, and this light has been shown to be harmful to our eye health. It is linked to numerous conditions, from the development of cataracts to promoting the development of age-related macular degeneration.
UV light exists on part of the spectrum that is just outside our ability to see, making them invisible to us (many animals and insects can see into the UV spectrum, but we humans can not).
Our exposure to UV rays mostly stems from the sun, though we can also experience exposure from man-made sources (such as tanning beds). It’s important to note that the vast majority of UV exposure (like 99% of it) we receive comes from the Sun.
There are three varieties of UV light:
It’s important to note that UV light passes through cloud cover, meaning that you are still being exposed when it is overcast outside.
For most people, protecting our eyes from UV is simple:
By taking these small steps we can greatly reduce how much UV exposure our eyes receive, minimizing their contribution toward any developing eye conditions. You only have one set of eyes- protect them!
