In my early 60s, I discovered I could not see properly with readers at 2.00 or 2.50 power. Then I discovered that no retailers in my area provided readers in 2.25 strength anymore. I even had to scour Amazon for quite a while to find these. I only wanted to order one pair, but for three at this price it was crazy not to. Actually, I was worried about the quality, but I am VERY satisfied with this choice. 1. These lenses truly are 2.25 power (I worried about that); 2, The lenses are properly matched, left-to-right; 3. The lenses are very clear - no scratches or odd marks anywhere; 4. This design has minimal frames, which I like; 5. They seem to be well built, strong yet lightweight with no loose parts, and; 6. I think they look really great on my face, actually better than any store-bought readers. I did notice the lenses didn't feel as slick as normal - I guess they were coated with some kind of temporary scratch protection - but they wash off readily with a little soap and water. These are far and away the best value I've ever seen for any off-the-shelf readers. I will order these again when I need 2.50s.
