Mirrors will make everything upside down.
That's why belay glasses come with prisms.

Yep, just what I was going to say. Mirrors won't work for belay glasses, you've got to use prisms.

Yup, you just wasted time and plastic.

If you want to build a DIY set, try this: Duct tape your smartphone to the top of your helmet, camera facing straight up. Then send the video signal to one of those snazzy new VR headsets.

It wouldn't be hard to change the design to accept prisms, I made belay glasses by taking the prisms out of a $5 pair of these

that is what I think I am going to do, the TV glasses have been on my radar for a while. The important thing is that the mounting surfaces are dead parallel which is the advantage of having this made by a computer. got any pics of yours Matt?

Plastic is super cheap $20 for 5lbs and the only time I spend making a pair is hitting file>print soooo thanks for hating on it.

Again not my design just though I would share because these are commonly a thing of interest, especially cheap ones.

I have a come and go neck injury so these make belays a little easier.

I made sure they were dead parallel by taping the prisms to a popsicle stick, then gluing them to the glasses. Removed the popsicle stick once the glue dried.

I think besides the prism change, the only thing you'd really need to change about the design is the folding mechanism for the arms. The problem with the pair I made is that they don't fit in a case, which makes them a pain to bring with you to the crag.
