I had bought pinhole glasses some 10 years ago, worn them a few times, after wearing had
pain in the eyes. Luckily i haven't used them since then.

so does this work if i cover all the holes around my eyes and leave one in the middle and if i can still see clearly does that works?
I think, you'll be able to see clearly only at some
one certain distance (for example - at a the far point only, and not at the near point) with these glasses then.
