in the left eye you have a spherical correction of +1.25 and a cylindrical correction (for astigmatism) of +1.25 on an axis of 180 degrees with a near vision add of +2.50 (for bifocals or progressives) wih a prism of 1.00 base up you would enter for the right eye: Sphere +1.25 Cylinder +1.50 Axis 4 Prism 1 UP Add +2.50 you would enter for the left eye: Sphere +1.25 Cylinder +1.25 Axis 180 Prism 1 DOWN Add +2.50 This is a pretty standard way to write a prescription, btw, the x 4 and x 180 are the degrees on which the cylinder correction for astigmatism lies in your prescription and this would be found in any prescription where there is astigmatism correction. Be aware that many of the online retailers do NOT make glasses with prism correction so you will have to shop around. I know that opticals4less does. -- Check us out at the oft-updated http://glassyeyes.blogspot.com! You received this message because you are subscribed to the Google Groups "GlassyEyes" group.
