I wear contacts and occasionally glasses.  I lost an expensive pair of prescription sunglasses on a paddle boarding excursion .. knocked off by a wave, glasses swept away at sea ... Later, I purchased an inexpensive (less than $20) pair of prescription glasses from Zenni Optical online. (My eye doctor was totally comfortable giving me my prescription and PD). They are now my go-to glasses in the ocean! Not only can I see well with them, they are "stylish" as well and if the ocean claims them, oh well, I'm out $20 ....
