If you are near sighted, do glasses help you see at all distances, near and far?!
Question: Since nearsightedness essentially means that the image falls short of your retina? So that even if something is close, the image is still slightly distorted even if is seems as though you see just as well with out your glasses up close. I'm nearsighted and it seems that even when I bring something to the distance at which I can best see without glasses, that glasses still help.

If you are nearsighted, glasses will put you on the same footing as someone who has normal vision, for distance and near.
Now, if you have a pure sphere refraction in the refgion of -1.00 to -2.50 equal R&L, you may find that closework is at least as good, and possibly better *without* glasses.
Particularly for fatigue, as you age. .
Someone of 45+, not wearing their -1.50 distance specs, is getting the same effect as a normal-eyed person wearing a pair of +1.50 readers.
(they'd both find the distance blurred if they looked up...)
But this finding short-sight "useful" does depend on there being no significant issues with binocular coordination, or astigmatism, or large differences in Rx between the two eyes.
In these cases an Rx given principally for distance vision will usually also show benefit for near.
If you are under 40, and have single vision lenses, then you should be able to see at all focal lengths from near to far. The lens in the eye can adjust and focus through your single vision lenses. As you age, and your lenses harden, and prebyopia sets in, you will not longer be able to see all focal lengths through single vision lenses, and will need to start wearing bifocal or progressive eyeglasses, or multifocal contacts.
I agree that I have gotten so that I like my contacts or glasses to see things up close, even though I see very well without them. In my case, I think it's because it corrects for astigmatism that even affects my close vision on sharp contrast objects...
I am in my 40's now and I am severely nearsighted. I am just getting to the point where I am having trouble seeing up close, but ONLY when I have my glasses or contacts in. Because I'm getting older and my eyes have changed when they correct my vision for distance it messes up my close up vision. Amazingly if I don't have glasses or contacts on I can still see even the tiniest writing up close just fine. Weird!!
