I probably should pay attention to these studies since I never wear sun glasses when I am hiking. I don't like to wear them because they change the look of the landscape and I prefer to see everything naturally and then I hate dealing with them every time I take a picture since I need to take them off to look through my lens. I also tend to leave them. In 2009 I brought a pair and managed to make it to day 4 and left them on the Tablelands some where. Medical studies kind of make me wish I had submitted myself for medical testing since I spent over 2 months in the mountains and did not wear sunglasses once.
I do burden myself with them just in case I have to cross snow since I have spent too much time on snow slopes with no sun glasses and it's miserable.
