Chums Neoprene Classic Large Frame Eyewear Retainer - Durable Floating Sunglasses Sport Strap

A quality company, 30+ years of their gear have traveled with me. Now that I wear glasses all day, I appreciate the floating function. My frames & lenses are light, so this actually floated. With heavy glass lenses, this slowed the sinking to a manageable speed. Bright color visible underwater.I'd like to see this with a double layer for some extra flotation.

This is the real thing. They work like a charm. I am able to do water sports with my glasses still on without losing them. Makes a difference when you can see everything.
