I created a prescription for computer glasses from my prescription for bifocals, and I am very pleased with the results. I followed some of the suggestions I read in earlier posts to this group about 1-1/2 years ago. For distance vision, my prescription is two low positive numbers for sphere and slightly different values of cylinder and angles for each eye. For the near-focus sections of my lenses, the "add" value is +2.0.
For these old eyes, my computer screen is too near for the distance vision region and too far for the close-up sections of my bifocals. What worked for me, and for my wife, too when she wanted computer glasses, was to simply add +1.0 to my prescription sphere numbers for distant vision (half the "add value for reading distance), keep the cylinder power and angles the same, and submit the resulting prescription for single-vision glasses, rather than bifocals. I bought two pair -- one for home, one for the office. I used to just buy cheap low-power reading glasses at a drugstore for my computer work, but my prescription computer glasses are much better, because they account for the slight difference in power between my eyes and correct for my astigmatism as well. I tried progressives, but couldn't adapt to them and found that their corridor for clear vision was way too narrow for me at my computer screen. I don't mind switching to my computer glasses when I use the computer and back to my bifocals when I leave my workstation. --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://glassyeyes.blogspot.com!
