That’s what I first thought of when I read the headline...not fully blind people.

I see fine with my glasses, yet would be considered legally blind without them. I make a point of occasionally practicing without my glasses (but, yes, WITH safety goggles!) at targets up to 7 yards.

The reason is that I might find myself having to fight without my glasses (either from them being knocked off at the start of the fight or being surprised while sleeping) and it's good to practice such scenarios.
