We use safety goggles. They fit overtop of my presecription glasses, you can get them with tinted lenses which is great for salt. They seal well against the face without getting sweaty and you can get clip on face shields which I use if the wind is stong and flinging up sand or salt. The best thing is they are very reasonablely priced and easy to get.

PS if you want your goggles to last longer do not wipe of the sand/salt as the lenses get scratched wash them of in a bucket of water or spray with a squeegy bottle

Yeah, I found that one out the hard way. Now I carry a gerry can of water on the side of the trailer with a tap so I can wash my goggles and me.
