With proper correction of my astigmatism, my vision tests at 20/10, but that relates to twenty feet away. NO problem at all for me. In fact I sometimes forget my glasses, because, generally, I can see just fine, but not up close AND the farther away a subject is the more my astigmatism makes it double and quadruple (etc.) the images I am trying to decipher.
I can not see well "up close" (meaning like reading the mail or a newspaper) any better than any other old man, I need my bifocals and then I can read tiny shit that some can not. Forget trying to see up close without my fancy bifocals.
I do recommend the "No Line" type. I do not have to switch glasses from infinity distance (photographic term) to within way up close to see tiny scripts.
They are not cheap, with all the additional coatings (various heavy metals, such as fine camera lenses use to reduce glare and anomalous refraction artifacts). In fact they are the most expensive glasses available.
