i have worn the lined bifocal for years. I recently got a new pair that work for reading and at a distance but I have to go to another single vision reading glass for my computer, I can move the computer closer and use my bifocal but this is not easy on my desktop. I tried progressive years ago and was not able to adjust. When I looked to the side without turning my head everything tilted side ways. I had to go back to my bifocals with line. I have been thinking of sending my prescription to zenni to give progressive a try again. i hoped that I would be able to have a focal distance for reading, computer, and distance. Keep us up to date when you get yours.
