Personal viewpoint on progressive lens. I tried them, with careful fitting by skilled eye specialist, and then went through 3 different sets of glasses, trying to get a fit I could live with. Total failure. Because of the lack of definition between near and mid and far they were a personal danger. Working with precision machinery was a disaster. Rather than being able to shift eye position to adjust for distance, it required continual head reposition in a "hunt and peck" system of trying to find usable magnification.... The interim fix was to switch to lined bifocals, with desired focal length set to my useful length. That provided a nice crisp shift horizon between near and far magnification that "progressive lens" never gave.. Also, the focal area of the lined bifocals was much wider which gave side vision improvements.
In December, last year, had cataract removal, both eyes, and fitted lens implants which corrected far and near vision, as well as astigmatism. After about 2 weeks, I now do not need to wear glasses at all... total success... although not cheap... I now have 20/20 in each eye and my wallet is much lighter.
