text: These glasses are great. I tested them this morning by taking my GPS and some directions on paper on a car trip. The glasses will take a little acclimating to, but I could safely read either my GPS or the paper directions in a quick glance. No need to perch readers at the tip of my nose to look over while driving. I just need to learn how to tilt my head to keep the bifocal line out of my field of view when I'm driving.<br /><br />Like other reviewers, I wish the tint were a little darker, but that's a matter of acclimating, too. I'm going to be a lot happier not stacking glasses or switching from readers to sunglasses all the time.
