When 3D is 2D
p2pnet news view | Movies:- Movies in 3D aren’t for everyone.
Not, however, because they don’t like it.

A polarizing filter in front of the left projector lens orients random light waves into one plane, while a different filter in front of the right projector lens orients light waves into a perpendicular plane .
Filmgoers wear glasses with gray polarizing lenses that orient light waves in the same way as the filters on the projectors. This causes the viewer’s left eye to see only the image from the left projector and the viewer’s right eye to see only the image from the right projector. The brain receives these two separate images and fuses them into one 3-D image.
But, “up to 56% of those 18 to 38 years of age have one or more problems with binocular vision and therefore could have difficulty seeing 3-D,” says a College of Optometrists in Vision Development press release, going on:
“In addition, about five percent of the population have amblyopia (lazy eye) and/or strabismus (eye turn) which makes 3-D viewing impossible.”
Not only but also, “Some people may have 3-D vision but feel nauseous or dizzy when watching Avatar,” states the college, saying this can be caused by ‘visual motion hypersensitivity’.
But maybe there is a no-glasses solution. And it’s called Crosseyed Freeviewing.
Yup.
“If you cross your eyes to line up the images so that you see 3, the middle one will appear to have depth,” says the Kroden35 in a GooTube video.
It takes a bit of doing, but it works.

i can’t cross my eyes.
but there are several types of high-quality 3D glasses available – not just those 50s-era crappy paper ones. there are ones for watching on different types of tvs and screens, as well as some that fit over prescription glasses.
and none of these are paper and cellophane.

“…up to 56% of those 18 to 38 years of age have one or more problems with binocular vision and therefore could have difficulty seeing 3-D…”
I wonder what the stats are on people who can’t focus on “laser art”.

I’ve been completely blind in my right eye since birth (doctor’s mistake that wasn’t discovered until years later). No version of 3D works for me.

I think I would more amused by a theatre full of cross-eyed people than any crap Hollywood could ever play in the theatre.

Thank you for this article! I have reduced vision in my left eye and can’t focus it to make 3-d images with those glasses. The industry needs to work on true 3d holographic technology

I guess I am one of the lucky ones; the Avatar 3D worked beautifully for me, and I didn’t have a headache after the movie; first time after a 3D. Best part was one of my scifi buddies that went that night saw his very first 3D in his life and it was AVATAR! He was practically in shock after the movie.
