I require glasses with a very high lens power to see across a large room, e.g., a lecture hall; in fact, I even need glasses to read a book in my lap.
But since reading near is naturally so much easier than seeing far, could wearing such a powerful pair of glasses while reading further damage my eyes? Does the distance and the lens power needed even make a difference, or should I consider a pair of reading glasses? By the way, I'm not interested in having an extra pair of glasses if there is no difference.
Thanks.
