If you have reduced neck mobility or range of motion for any reason, these glasses are amazing! They have mirrors instead of lenses. The mirrors flip your vision 90 degrees downwards. I use them to paint and work on projects while sitting at a table. I can sit up straight with perfect posture and still see the table top! With these glasses you won’t have to bend your neck at all.
Here’s a link to the one’s I ordered off of amazon. There are several different companies that make them, but according to reviews these were the lightest pair.
If you use glasses their are versions available that allow you to wear your normal glasses underneath the prism glasses.
