If you want to do arcade VR you'll need to solve the Pink Eye problem before I get anywhere near it.
There's a pink eye problem with HMDs? This is the first I've heard of it, but I suppose it makes sense.
Yep. A local company in OC is currently developing a VR headset condom that will solve the hygiene problem. Going to a bunch of meetups and trying out VR can get disgusting.
