Explanations and videos of visual conditions such as nearsightedness, farsightedness, and astigmatism, as well as eye diseases such as cataracts and macular degeneration can be found here.
I have been wearing progressive lenses for many years but have never really been satisfied with them. Both my far and near vision was not as crisp as I thought it should be. But since my eyes were examined and glasses were made by two separate optometrists, I thought maybe I was just being too particular. Then, when I was due for a new pair of glasses, I decided to try Normandy Optical. What luck! My vision is now better than it has ever been with glasses; both near and far vision is very crisp. I would highly recommend Normandy Optical to anyone wearing glasses.
