Girlfriend has trouble watching digital 3d!

Penpal

A group of friends, my girlfriend, and I went to see Cloudy with a Chance of Meatballs (which was awesome) and enjoyed the hell out of it, but when the movie was over my girlfriend said that the 3D in the film was doubled sometimes. Lines would be doubled, throughout the film, making text (and generally everything) blurry. I've googled for some answers, but I can't find anything at all... She is wearing the glasses, yes, and it has happened for other movies so I wouldn't say it's a pair of RealD glasses with one lens that isn't polarized doing it.

Help me figure this out!
She has really good (supposedly 15/20) vision and has never needed glasses.

Digital Light Projectors play hell on my eyes as well, which is a bitch because a lot of my lectures at school use them.

Some people are just susceptible to it.

Some people never really develop proper depth perception, but still live regular normal lives. Except when they try to view 3D movies and stuff.

She has one of a variety of vision problems based around her eyes not focusing normally. Probably not important, though you could always visit an optometrist to see if they could figure out what the problem was.

Some people just can't see 3D effects, it's to do with the way their eyes focus, it's going to be a bigger thing going forward.

She's left eye dominant. Have her flip the glasses over the next time she watches a movie.

I'm full of shit, but damn that sounded good. Seriously, I can't see 3d movies at all. all I fucking see are double images everywhere

How good are you at judging distances?

Pretty good. I am somewhat near sighted and have some astigmatism, but I'm correctable to 20/20 with glasses.

Sorta on topic: Does having glasses affect this? I tried to watch Coraline (on DVD) in 3D and.. it didn't work? Dunno. I didn't see double images so much, just things either looked greenish or reddish.

I don't know if it applies to the newer 3d technology, but color blind people used to have trouble seeing 3d. Maybe she's slightly color deficient? She might not notice unless she does a lot of work differentiating colors.

Isn't 15/20 75% ?

Penpal

Yeah, I mixed those up. It's 20/15, for something a normal person would view as 20 feet away she would see it as if it were 15 feet. My bad.

She is relieved that she isn't alone in this 3D thing, too!

I don't think this is it. New 3D films use glasses where one lens blocks vertical lines and the other lens blocks horizontal lines, unlike old 3D glasses that blocked red and blue.

BlazeFire

Yes, the new Digital 3D glasses and projectors work off a property called polarization. Did she try looking at the screen without the glasses? I would be curious as to what it looked like to her there.

Iroh

It definitely could be due to focusing problems, and if so it can be corrected. My younger brother had issues with convergence, and a lot of the exercises the optometrist had him do utilized 3D glasses.

Penpal

Thanks iroh!
I'll let her know.

They're circularly polarised, rather than linearly, otherwise the effect would fuckup if you tilted your head.


I notice that doubling too, I think it's just the two projectors not being lined up properly.

This. I had eye surgery whan I was 7 to correct my left eye, which was turned in slightly. A side effect of the surgery I actually don't have "proper" depth perception like other people have. I can still measure distance, etc, but I do it a bit slower than most people, and not quite as well (parallel parking is even more of a bitch for me because of this).

Because of this, I basically can't see 3D shit in movies very well. I can a little bit, but not enough for it to matter. This is why I cringe at the "zomg 3D movies are coming everywhere!" thing that is going on right now.

jorax

I have 20/13 vision in both eyes and haven't had any problems with the new 3D movies. The ones from when I was a kid gave me headaches, and I'm really not good at the "hidden image" pictures either (not sure if any of that is related to visual acuity).

Modern digital 3D is actually projected from a single projector, not two, I believe. At least, that's what I was able to get from the wikipedia page for RealD (which is what every theatre is using nowadays).

I have the same issue with watching 3D movies my lack of depth perception however is caused by being blind in my right eye

Scrublet

Throwing another vote towards the depth perception root cause. Without glasses, I have 20/20 vision. However, a series of tests done by AFROTC indicated that about 80% of my vision comes out of my right eye. I now wear mild prescription glasses that balance them out, and use that on the rare times I see something in 3D. To be honest, I'm not really buying into the whole 3D push that's happening right now anyways.

Improvolone

It can't help that it costs more to see a 3D movie.

Dalboz

3D movies make me ill. I can see some 3D effects, but I see a lot of double images. The reason is that the tendon in my left eye is a little too tight (I was born with it), so it skews my eye just enough to mess up my depth perception, making me very right-eye dominant. I see everything like a TV screen, where you can tell there's depth there but can't really tell how much.

So, from personal experience, I would also say it's a depth perception thing.
