I wear extended wear contacts. I don't really change much for the playa.
The playa is dusty and yechey and horrible. I can do that in my contacts. Heck, I can clean my contacts in a shot glass of vodka and be good for a week!
If you need nice clean contacts, you will not have them on the playa. Even in a $Milion RV. Dust is everywhere!
Given I wear contacts; if I really needed to go, without contacts, I could do it. The place is huge. Unless you have some horrible vision you should be able to find your way home.
