Most of us know we should protect our skin with sunblock. But sunblock for your eyes? Yes!
The sun produces a vast amount of electromagnetic radiation, some of which we perceive as light. Just beyond this visible light rays lies the spectrum know as ultra-violet light. UVA and UVB rays are both harmful to our bodies. Not just on hot, clear days but even on overcast days.
These rays can pass through clouds and in the winter your eyes can get sunburned or snow blinded by the UV rays reflected by the snow. This highly charged energy of the UV spectrum can disturb the DNA in the body's cells causing mutations that can result in skin cancer. Similarly excessive long term exposure can lead to cataracts, macular degeneration and liaisons on the white of the eyes.
So rub that sunblock on your arms and get a good pair of sunglasses that provide both UVA and UVB protection. Your eyes will thank you.
