DHdriver is spot on with one of the "potential" probs...I too was advised that the likelihood of the eye drying out in the low humidity environment at altitude (and the associated irritation) meant specs were the better proposition.
Note: This was quite a few years ago and contact lens technology has obviously come a long way since!!
While specs are most definately a pain in the proverbial........you may also find that contacts are just as troublesome to look after in some of our beloved flying jobs with their associated dirty, dusty environs........eg. mustering, BDV races type scenarios.
If you decide to go with the contacts, I'd be interested in hearing how you/they fare........PM me if need be once you've given them a try.
Thanks Aerocat........your answers alleviate quite a few of my concerns, although your beady little peepers may be particularly more tolerant and tougher than others out there!?
