James, you left out the PD. For Progressive lenses the thing to get them right. I ordered several pairs of progressives and they are all spot on fantastic!
Ana, ADD is always (of course, I'm sure there are always exceptions) the same for Left and Right. Sometimes they mention it only once on your prescription. To illustrate: For my prescription I need ADD 2.25 to be able to read. Since I have got R +4.00 (amblyoptic) and L + 1.75 I actually should only need an ADD in my L lens, since +4.00 is in my case fine for reading anyway. But since ordering two progressive lenses online is still cheaper than buying them at a highway shop, I'm still more than happy to pay for the two of them. By the way, my glassless friends who say they are glad they have no need for glasses, (hahahah) are always grateful to me, when they can borrow my glasses to read the menu in a restaurant..... So a social function for them as well. Grz Caro On 6 apr, 11:18, "[email protected]" <[email protected]> wrote: > The Add will apply to both eyes.
