Very helpful
I wear these glasses positioned over my regular glasses for TV watching in bed. They work great for this purpose. The TV screen is smaller when viewed through the lenses but the comfort of laying flat more than makes up for this. I don't need glasses for close up reading so when I read I takeoff my regular glasses and just use the prism lenses. They work great for this purpose. I also first saw them in "The Bucket List" movie. Glad I did!
