My computer progressives are fine and a standard page width is fine for reading in terms of sharpness. I do have some issues, including with my "standard" progressive pair due to my Rx, which includes correction for astigmatism and I have prism correction in both lenses.

*Prism, for those interested, actually force a horizontal shift in the image, in my case inward in both lenses to correct for eye muscle discrepency. Otherwise, I get strain and headaches from working so hard to see a single image, versus double. <ha, joy>
