Second, get sunglasses that have hydrophilic rubber nosepieces, temples, and ear hooks. Personally, I prefer glasses that actually have adjustable nosepieces that stick out, vs those that only have a rubber strip that goes over the nose.
I couldn't find any with hydrophilic rubber in my local sporting goods store. Actually, I only looked at the discount rack ($20 and below). They might have the good stuff inside the display cabinet, but I didn't bother with those because they are in the $100 plus range.
