Who uses sunglass when they shoot?

I always wear sunglasses when I'm outside period. If it's sunny for sure when I'm shooting. Also a ball cap as well which helps with glare. Guess it goes with being a farmer and always outside but if I don't have sunglasses I get headaches or can barely keep my eyes open from the brightness. Even sometimes when it's cloudy outside like today I need sunglasses most the day.
 
I wear an inexpensive pair of tinted safety glasses (ANSI Z80.3-1996) compliant. They block-out 99.9% of the UV-A and UV-B light up-to 400nm. Both of my grandfathers who were farmers and my dad had cataracts. As the ozone layer gets thinner, UV-B radiation at the surface of the Earth increases. Folks who live in the South and South Western US are exposed to more sunny days than those in the Northeast and Northwestern US. Older folks who have cataracts have become common in this part of West Tennessee.
