With the 3DS and other 3D technology gaining in popularity, I’ve been finding out that there are more and more people like me, vision-wise: People who have trouble seeing 3D or can’t see it at all. I’m glad that I was diagnosed as a baby and had eye surgery while I was still too young to remember it (though old enough to remember the embarrassment of wearing an eye patch… kids who grew up during the pirate fad probably had a distinct advantage there). I still don’t have perfect 3D vision, it goes in and out and I don’t really notice the difference most of the time. I technically still have some strabismus as well, but not to a degree where anyone but an eye doctor would say I’m cross-eyed. I’m guessing a lot of people who are frustrated by the prevalence of 3D media have one or both conditions, but to such a mild degree that it doesn’t affect their daily lives, but is incredibly frustrating when they realize they’re missing out on something others see effortlessly.
Oh, and here’s the tl;dr version, with concrete examples: Pilotwings 3D works for me most of the time, Street Fighter 3D is a blurry mess.
