We put on the Leadout Pivlock Polarized Sunglasses for days where the rays are always getting in our way. It has polarized lenses to ensure we're not blinded when coming around corners into direct light. The strong nylon frame also gives us the confidence it won't shatter if it falls. Chances are it's not going anywhere though--the Megol nose pads provide a secure, non-slip grip even if moisture is a factor.
