Until I had my cataracts removed I couldn't read my computer screen and needed extremely bright light.  I worked part-time in a friend's quilt shop and could barely tell one color from another.  My sight was deteriorating rapidly.  These glasses were a sightsaver as well as a lifesaver!  Suddenly I could see the computer screen.  While it seems hard to believe, colors were clearer (must be something about yellow under fluorescent light).  While my husband says I looked like Willie Wonka, I didn't care - I could see!

I highly recommend these glasses for anyone with low vision issues.  I was able to see so much more clearly, and they even helped with the sun.
