I immediately could see better when putting these on. I think the prescription is more accurate than those I got last year or they are aligned to my eye better.
I never felt comfortable in the last pair. They didn't seem to be aligned correctly and I did feel eye strain, especially doing alot of computer work or night driving. Night driving seemed like I was lookin out of the bifocal part of the classes and I had to keep tilting my head to try to find a comfortable clear view so that I could drive.
I haven't driven at night yet, but everything else just feels better with them!
