I'm legally blind without corrective lenses. When I go to bed at night I put my eyeglasses on the nightstand beside me.
However, when I wake up I just don't have any problem seeing. I simply don't notice that my vision is impaired without my glasses. (The problem I expereince is adjusting to impaired vision after I've been wearing my eyeglasses and then take them off.)
When I played HS football in the 70s, there really weren't any sports frames for eyeglasses. (And even if there were some halfway decent sports frames back then we couldn't have afforded them.) I practiced and played without my eyeglasses. I played well, and never had a problem I could relate to not wearing corrective lenses.
I train at the shooting range without corrective lenses, a must, IMO if you wear eyeglasses.
My patrol eyeglasses were prescription safety frames, solid nose piece, and spring hinge temples. I carried a pair of those godawful ugly black Cris Combat Specticles, which are equipped with a rubber head strap, in my breast pocket as spares in case my primary pair got broken in a fight or lost.
I wrote an article, published in Law and Order magazine in 1994, for patrol officers who wear eyeglasses.
