My husband refuses to wear contacts, but he has to constantly switch between his pairs of glasses because he cannot stand bi-focals. It drives me batty. He carries a pair of reading glasses with him, but then has to have distance glasses for nearly everything else. I become his eyes for him when we are out and he needs something done that requires up-close reading. I have encouraged him to get contacts so all he has to do is worry about reading glasses, but he says contacts will bug him too much. (Even though he has never tried them.)
