Their lenses are good and clear, they don't give the impression that you are looking through transparent plastic, but at the same time they are very small - which, combined with the thick frame, makes reading uncomfortable and forces you to constantly turn your neck back and forth for a better viewing angle. The frame is also somewhat hard and rigid and when I wear them my Pontic nose hurts. I'm afraid they are only for moments of need and for one or two minutes, not for hours and hours of comfortable reading as I wanted them for. In short, I wasn't very impressed.
