If you had strong ones it would be hard to look down like that on a bridge and walk fast. Judging distance and strength of boards at that angle would pose a problem. I actually used to measure for the glasses and cut the lenses. I know what I am talking about. I was a optical technician and then worked my way through college for my other degree. 250 or more he would have problem..
Sorry but I am right on this one...
Some problems with HD progressive lenses occur when walking up and down stairs. Since the reading correction is at the bottom, the stairs may seem like they bounce.
You should always point your head and chin at what you are looking at...
Doctors recommend becoming a head-turner as opposed to an eye-mover when wearing progressive lenses. Lower your eyes, not your head, when reading. Dont look through the sides of the glasses, as peripheral vision is distorted through PALS.
