Take the tour ×  Someone told me that reading glasses (a priori
with a magnifying glass effect only) improve one's eyesight of
objects lying in the long range distance. I am really sceptic
about it since everything is blurry if I look at objects through
those glasses! Is it possible (for this particular person at
least)?  share|improve this question I'm not really sure what
you are getting at here. I, for one, and near sighted, which
means I cannot see things clearly in the distance. For me, this
is at about 10 meters or so and I cant clearly read something as
large as a scoreboard. So for me, glasses do vastly improve my
eyesight for objects lying in the long range. Is the question
can this be done in the general (normal 20/20) case? I know
there is a limit to what you can clearly see based on the
properties of light and the distance between your eyes, so that
would be the limit, I'm willing to bet that is nearly reachable.
