Anytime I've had my contacts pop it was becuz of dry eyes -- I was having problems (have worn them for about 25 yrs!) with contacts though in the last few years drying out at the end of the day. I switched to the new Acuvue contacts that have extra moisture (can't remember the name, Oasys was one brand but not the ones I bought) *plus* I use the new saline with "moistureloc". They helped, they even helped when flying as I do overseas trips and just don't like putting on glasses for long periods.

My eyes are a bit worse than yours (-5 and -6) so they do have contacts for your strength. And yes, bringing an xtra pr along is a good idea (but I usu don't!!) -- I have the drops I use at stops.

And I also have the more wrap style sunglasses designed for a woman's face, they keep the elements out a little better I think than the larger men's sizing.

Some things to consider...I wish I wasn't too squamish to go and look into Lasik....
