MRI Fitover Non-Magnetic Prism Glasses

Apparently a lot of the previous reviewers expect more from these than the Laws of Physics allow. These use relative simple, but precision, prisms that turn the light 90 degrees. There are no lenses or mirrors or other optical elements. To make the field of view wider, one would have to either put in a negative lens, which would reduce the size of the image, or else use larger prisms, which, since they are solid glass, would substantially increase the weight of the glasses. That being said, the glasses serve the purpose for which they were designed quite well. The prisms are clear and distortion free, and the frames, though plastic, are quite sturdy. I have used them quite a lot for reading and watching TV, and they work very well. They are a little heavy, but that, to me, is more an indication of their sturdy construction than anything else. The only "Con" I have has to do with shipping. They are shipped in a small cardboard box, wrapped in a cushion of tissue paper. Unfortunately, this does allow them to rattle around inside the box a little. When I received them and opened the box, one of the retaining frames that holds a prism in place had come loose, allowing the prism to shift position, It wasn't too much trouble to fix, so no real harm done, but I do think more secure packing would be a good thing. They shipped quickly, and I received them on the expected date. I would definitely recommend these to a friend.

These are great for using a laptop or reading a book in bed. I am able to lie flat on my back with my laptop on my chest and watch movies or browse the web. Works good for reading too. Before I got these I had issues with a pinched nerve in my neck due to so much laptop use with my head propped up with pillows. These glasses are a great value, good product for the price. They fit over my prescription glasses without issue. They do weigh a lot, due to the glass prism, but this is unavoidable in this type of product. I added some stick-on foam nose pads from the drug store for comfort. The field of view is somewhat limited, but works fine for reading or a small laptop screen. They're not adjustable, so the spacing of the lenses won't be perfect for everyone. It can cause some eyestrain when used for more than an hour of so. This isn't a high end product, but it's the best model I've found in this price range. There is a fully adjustable model that goes for around $100 if you need it.

Good alignment of prisms, and fit over glasses well. Nose rest not comfortable, and must carry a heavy set of prisms. So use laying on back not so good.

Returning it, very heavy and the prism have strange artifacts in them. I went with the one sold by Dynamic-living and I'm much happier now.

I was hoping these glasses would be a solution to my reading in bed and my nagging back problems. I find these glasses are too heavy and uncomfortable to wear to a point where I have sore spots on my nose. The peripheral vision of these glasses is also very limited. The concept of these glasses is great, but the next generation prism glasses hopefully uses lighter materials that would allow a wider field of vision. Update August 4: I can't help it, but it's been nagging on me to update this review. I have not worn these glasses for several weeks and my nose is still bruised from wearing them. I never wore these glasses any longer than 20 minutes at a time when I did use them and yet they left their marks. They weigh 3.2 oz versus 0.9 oz for one of my regular reading glasses.

I agree with the complaint that they are heavy. I find that noticeable when sitting up. When laying on my back I do not notice it. I agree with others that there is too much blocked in the middle but I also found that it does not bother me very much once I've started reading. They seem to make the TV or whatever I'm looking at smaller. They fit over my reading glasses and they are reasonably large framed. I'm pretty happy with them. I'd like to see a product like this with an in-out bridge adjustment. But for under $10! These are excellent. Also the shipping on this product/this link was very fast and that was despite that, because my combined order was high enough, I chose free shipping slowest option.

I use the over glasses lying in bed to watch television. You can keep your head flat and look at the ceiling and see the TV. They work well but they are a little heavy on the nose. Good for people confined to bed. Saves any neck strain.

Works really well but doesn't fit me at all so I need one hand to hold them up or they just fall off my face. Partially because they're really big and partially because they're really heavy. And they look GREAT :p (sarcasm.) But, I have multiple spinal fusions and can't bend my neck without straining disks, so it's a pretty good solution when I need to 'look down.'
