Birmingham Anglers Association

After three lots of eye surgery, my vision still isn't perfect, but it's a lot better than it was, and I always wear glasses for fishing - so here are a few observations.
Polarised lenses are great for fly fishing, lure angling or any other method that requires that you see into the water, but (as stated above) they are terrible for float fishing.
Don't fly fish without glasses - even if they are just cheap driving glasses. I've seen a hook in an eyeball, and it ain't nice.
Avoid green mirrored lenses. Trees are green, and if the lenses on your glasses reflect away the only light getting through the tree cover, you can't see where you're walking.
Glass lenses are great, but in the UK climate, they fog up very easily - stick with plastic.
If you need prescription glasses for tying hooks etc, go get some cheap ones. Mine are from Ali-Express - they are full sized glasses and I usually have a couple of pairs in my gear.
