ADJUSTABLE & REVERSIBLE BED PRISM SPECTACLES GLASSES

I was able to use them for about a week before the head piece broke and they became useless. At $89 plus shipping and handling, that came to about $12 per day.

Adjustability is good but rather heavy and hard to keep positioned properly. The reversible part is not needed for me so I would prefer just the ability to adjust up and down maybe allowing less weight.

This is an excellent product. It fits over my regular glasses so that I have a very clear television viewwhile lying in bed. Being able to adjust the angle of the prisms means that I can do this whileputting my head into the most comfortable position. I will say that I found it totally unusable for bicycle riding and only a few minutes trial made me feel that they were quite simply very dangerousfor this application and I simply looked around them while I rode back home never to subject myself tothis dangerous trial again.One thing that they need to fix is the lack of sufficient friction in the angle hinge on the nosepiece. It isn't adequate to hold the glasses where you put them and I had to put paper shims in the hinge to get enough friction to keep the glasses at the angle I liked.

great for people with neck and back pain
