Eye protection is very desirable. I always wore glasses when fly fishing. Polarised. I saw a photo of someone with a fish hook in his eye and I had one in my lip once, 3 stitches after it was cut out. Also I got caught in a hailstorm in the Mog on the M4, roof down. The hail was really stinging at 70mph but sunglasses saved my eyes.
My current go-to sunglasses are Serengeti with a wrap round. I have a couple of spares, Polaroid and Rohan.
Aero goggles don’t do it for me, even with a flying jacket on. I think an M3W should have them as part of the deal when buying!
