Hi,
Sorry if this is a silly question... I have seen a pair of old binoculars in an OP shop. At first I thought I don't need them, but then when I came home I thought they might be good binoculars and also suitable for night vision. So I was thinking of going to the shop again tomorrow to have a better look.
So my question is.... Is there a way to check their quality and also if they are suitable for night vision? The people who work there won't have a clue, so I should have a clue myself.
Thanks!
