Very poor quality all around. Do not improve vision.
These glasses have very poor quality. I bought glasses from three different places from Amazon. All three sets that I purchased were the same strength multi-focal progressive glasses. Two of them were very good. This brand was very very bad. I should have listened to the other reviews. Putting them on was very tight and painful and looking through them was very blurry. I would not consider these progressive since you can see the lines. The design of the magnification and lenses are just plain off. I couldn't see anything through these.
