Hey guys, is there anyone out there qualified to explain to me, what the vision number measurements(like 20/20, 20/50), mean, and how are they determined?
BTW-- I DO wear glasses... Have for about 13 years now, and should've years before that.
OK, I'll try........
20/20 vision is "normal". That means a person with "normal vision" can read the bottom line on the standard eye chart at a distance of 20 feet. So if you have 20/50 eyesight that mean that you have to be 20 feet away while those with "normal eyesight" can see it at 50 feet.
BTW, as a teen 'we' had a friend with 20/200 vision (almost legally blind). As such, he had to get a letter from his eye doctor so he could get a DL. He wasn't supposed to drive at night, which he did - that made for some 'fun rides'.
