For what it's worth, I tried progressives from Zenni, hoping they would be useful for working at my computer workstation, but did not like them. Blame that on me, not Zenni. The corridor for sharp vision of my PC screen was too narrow for me, and I found that too distracting. In fact, I could not adapt to progressives at all after an honest 2-week effort and went back happily to bifocals. For computer work, I simply ordered a pair of single-vision glasses with the spherical powers equal to the sum of my distance-vision sphere plus half the add for close vision. The cylinder numbers are the same as prescribed. These work very well for me, and I am satisfied.
You are trying to avoid changing back and forth between glasses, so my solution would probably not please you. I have some comments on your prescription, however. If you do not need glasses for distant objects, and your reading prescription is +2.50 for one eye and +3.00 for the other, then it seems to me that with a computer prescription of +2.00 and +2.50, that the add for reading should be just 0.50 (added to the spherical numbers for computer vision). That would give you the +2.5 and +3.0 for reading. Adding the reading numbers to the computer numbers for your "adds" to get +4.5 and +5.5 will result in a very close reading distance, I would think -- not far from the front of your nose. My "add", for example is +2.0 for both eyes to get me from infinity to standard reading distance -- about 14-15 inches. With what you have told us about your vision, it looks like your prescription for progressives should be something like right and left sphere numbers of 0.00 (no distance spherical power), the cylinder values you have stated, and adds of about +2.5 and +3.0 for close distances. Your computer screen with these glasses would then be sharp when viewed somewhere between the top and the bottom of your lenses. Let's hope you receive some more opinions on this forum to help sort this out. I do think that if you're going to try progressives that you should have your prescription confirmed so that you get the best possible numbers to submit. You might need just a little sphere for distance vision to go along with your cylinder specification and progressives, in my opinion, are less forgiving of small errors than other glasses. An alternative, of course, is trifocals. Plano (no correction) for the top, computer numbers for the middle, and reading numbers for the bottom. I do not know whether or not you can get trifocals from one of the on-line suppliers though.

Is this how Zenni would make my progressives? --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://www.glassyeyes.com!
