Do sunglasses really help to keep my eyes healthy?

I cannot stress this enough…YES!

You know how the sun’s UV rays can harm your skin wrinkles; premature aging and skin cancer are some of the dangers of unprotected sun exposure. The same rays that age and damage your skin can and will hurt your eyes as well. Strong sunlight, and artificial light from sources like welding arcs or tanning lamps can burn the surface of the eye, much like sunburn on the skin.
