Vision Gadgets

I sometimes feel like experimenting with my vision. I've considered having "Prism Glasses" and also sunglasses.

  • Are there any sunglasses you use to remove brightness and find neat (or other kinds of glasses)?

I was thinking of glasses that could narrow my field of view removing movement which may happen in the periphery.

  • Do you have any of these rare vision needs or ideas? (To be clear, I'm not talking about fixing standard vision issues).

Beyond glasses I do like spinning wheels.

I also a screen with nature slideshows or static (https://www.youtube.com/watch?v=ubFq-wV3Eic) but not always. I wonder how common is that for others.
