Compared to other prism specs, do these sacrifice field of view to achieve the lighter weight?

The glasses use lighter frame materials and simpler appearance design, so they are much lighter than the previous prism glasses.

Does it weigh without packaging?

The weight of these glasses is about 0.09 pounds, which is much lighter and more comfortable than the old model.

What is the inside width of these glasses? I want to make sure they fit my head.

The widest part is about 6 inches, which is suitable for most people. The glasses frame has certain expansibility. The gray part of the glasses frame is made of soft material to enhance the wearing comfort.

can I wear these in an MRI tube?

Check with the technician. I can't imagine why would would need them as you need to stay perfectly still and you cant be bringing anything in the tube.
