Hi. There are front of the eye doctors and back of the eye doctors. If the “floaters” get bothersome, get thee to an eye doctor. If you see stars or flashes, go forth with good speed to the office. Ask the doctor why.
My wife and I did high alpine climbing when we were young. The polarized lenses were pitch
black and the glasses had leather side panels
Bounce, off snow or water
, not a good thing. Lots of information on climbing webs about the correct lenses.
The USCG requires spare glasses if you wear them. Good advice
Lots on the forum about binoculars.
Manatee eyes close like a camera
not a window shade.
Somehow, they smell pizza or beer
Happy trails to you
