I have worn glasses for about 15 years now and just got new ones. I've had graduated bifocal before but the new prescription seems to have changed the focal length from what was probably 18" + to 12" to get a really clear view of what I'm reading especially on the computer. Is this normal for some prescription changes or do I just have to work at getting more accustomed to the new glasses. The other issue is that one eye seems to be more difficult to focus than the other. I've been working with them for almost a month and still can't make the adjustment and I need to go back and get something changed if they are not correct. Am I crazy or is it possible the lenses were made incorrectly.
