I have been wearing my reading glasses even when I'm out and about and not just for short distances. I find them better than bifocals, but can wearing reading glasses most of the time damage your eyes?
No you won't damage your eyes. But it does indicate that your prescription may be too weak for reading, which is why you can get away with walking about in them and presumably seeing reasonably well in the distance. If you have an eye test you may find that you need a stronger reading prescription. But don't worry, you won't do any harm, although I would be concerned if you are driving in them. It would be best to have an eye test and at least find out how much of a compromise you are making by not having a separate prescription for distance and near.
