Any issues with this in the backcountry/altitute/whenever? I'm a corrective lens wearer, and for years would wear my contacts (Now the Acuve Oasys) multiple days. Few years ago found I just can't do it anymore. After a night, one of my eyes just starts to feel grainy and hurt. So now I just carry case, small solution, and glasses (back at camp). 
  
But, I dream of Lasik every day. Someday. 
 
no problems - every few years i have a dream where i'm like the untermensch again but other than that it's a total life-changer
