Taking the advice of the product description I ended up taking out the computer lenses and having prescription lenses put in instead. When you first get the glasses they are very stiff and take a while to loosen up but when they do they are very comfortable. The biggest downside about the glasses, however, are the golden sakura flowers etched on the end of the ear frames. These will turn green after you wear them for some time. Even being gentle while cleaning them the gold will come off leaving you with just an etching of the flowers instead of the gold trimmed etching like in the photos. This is a major oversite that really puts a dent in the appeal of these frames.
