Please excuse my ignorance. Is 3D a worse experience for people with monocular vision, beyond having to wear the glasses for no benefit? I would imagine it just automatically degrades to 2D.
I (obviously) don't watch 3D movies too often. When the technology first came out, it was really bad and gave me not-quite-headaches, not-quite-nausea when wearing glasses. It's better now but I don't get nearly the effect that the movie makers are going for and some of the more blatant effects (like things jumping out of the screen) end up looking weird and off-putting -- like getting half an image and stuff.
Edit: Typo and better explanation of the « trick »
There should be options for people with disabilities of course, and AFAIK 2D movies still exists and are not going to die anytime soon. But what are you debating for ? Do you want a global ban on 3D because it can not be enjoyed by everyone ?
I must also kindly reject your example. You can ski without legs. Ski slopes are actually a very good counter example: everybody who can pay a lift can go.
It’s a different question that I do not addressed, but I do not believe a ban will work. It’s better to regulate and put checks and balances in place. At least IMHO.
