I use a pair of extreme spots protection.
They fit and are held in place with my helmet.
THey are great because they are designed to sit high with plenty of lens above your eyes, so great peripheral vision especially above.
If it's late enough in the day and the surf is agressive where I need more depth perception I will go without them.
When I was testing these I used a dumbbell to drop on the lens. I broke the dumbbell before I could break the specs lens.
Helmet and the sunglasses work well together.
They are inexpensive.
