Good advice all around but this seems the most reasonable to me. The difference of ADD values of .25 (3.00/2.75 and 2.75/2.50) isn't very much. The practical effect of splitting the difference at 2.75 is that your mother may have to hold reading material in a more tightly controlled distance from her eyes than if she had the proper values in each lens. I say this because when I get an eye exam the optometrist asks me how far away do I want to hold things I'm reading? I give him a distance and he adjusts the ADD value to compensate. -- Check us out at the oft-updated http://glassyeyes.blogspot.com!
