Around 12 percent of the population struggles with depth perception, also known as stereoblindness. For this segment of the population, 3D movies are nothing special. Many people with stereoblindness don't recognize the condition, since they have never seen the world in any other way.
Some people simply cannot watch 3D at all because they are “stereo blind”. Their brains cannot triangulate between their eyes, so 3D is not even on the bribery list on movie night.
Individuals who have vision conditions such as amblyopia (an imbalance in visual strength between the two eyes), strabismus (misaligned eyes), or other conditions that inhibit focusing and depth perception will have difficulty seeing 3D.
One reason is that many 3D films were converted from 2D, resulting in a weaker 3D effect and poor quality, which led to audience dissatisfaction. Additionally, the high cost of 3D movie tickets and the discomfort of wearing 3D glasses contributed to a decline in interest.
This lack or absence of depth is one of the signs that the binocular vision system is not functioning properly. People who are unable to use both eyes together to achieve binocularity will not see the depth of 3D content.

Accommodation refers to the eyes' ability to maintain clear focus while switching between near and distance vision. 3D entertainment requires a constant switching between objects that seem to be closer and farther away. A person whose eyes don't accommodate properly will experience blurry vision.
They have existed in some form since 1915, but had been largely relegated to a niche in the motion picture industry because of the costly hardware and processes required to produce and display a 3D film, and the lack of a standardized format for all segments of the entertainment business.
Full rim passive polarized or active shutter glasses are the specialized eyewear required to enjoy a movie in 3D. If you take off your 3D glasses during the film, you'll see a pair of slightly overlapping images that are a little out of focus.
Johnny Depp has said he has no stereo-acuity and cannot see his “Pirates of the Caribbean” outings in stereoscopic glory — which may not be heartbreaking for him.
3D vision, also known as stereo vision or stereopsis, describes the sensation of depth from combining two slightly different pictures seen in each eye into one 3D image. When the eyes don't work together to make this 3D image, it is known as stereo blindness.
Praying mantises are the only invertebrates known to see in 3D. The predatory insects excel at detecting prey that comes within striking distance, but—unlike us—their depth perception only works when the prey is moving.
Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes.
The most common and easiest way is to simply wear the 3D glasses over your eyeglasses. This sure is uncomfortable and can be heavy on your ears but the quickest tip to follow. There may even be special 3D glasses available in some theaters that can be worn over regular glasses.
However, the glasses may have an adverse effect on a child with lazy eye. When they put on 3D glasses, the lenses may create a viewing condition in which the brain gives attention to the suppressed, amblyopic eye. Unfortunately, this often leads the eye to strain, resulting in dizziness, headaches and nausea.
You need a 3D TV or video projector, a 3D-enabled Blu-ray Disc player, and some 3D-compatible Blu-ray discs. If you want to watch 3D content via HD cable or satellite, you need a 3D-compatible box and a subscription to 3D channels. You need to wear glasses to watch 3D. However, these aren't the cheap paper glasses.
To stream 3D video from a Blu-ray Disc player or steaming media player with a Netflix app, the TV must support 3D through an HDMI connection. The device you are using to stream the 3D video must have a 3D-enabled Netflix app installed.
Amazon prime will allow you to stream a number of 3D films through their streaming service if you have the appropriate hardware to view stereoscopic movies.
Unfortunately, Cameron was right. Many home 3D TVs used the active shutter system, requiring a pair of glasses that would essentially open and close rapidly in sync to produce the 3D image. It's these glasses that required charging and made 3D a little bit more cumbersome in the home.
Between Apple's head-mounted personal movie theater and a new generation of glasses-free 3D monitors, it looks like 3D experiences are poised for a big comeback.
In most cases you will need a 3D-enabled display/monitor, 3D software, compatible graphics card, compatible 3D glasses with a compatible 3D emitter, and a Blu-ray™ Disc drive & Blu-ray™ playback software.
Depth perception is the ability to see things in 3 dimensions and judge how far away an object is. You generally need to have binocular (two-eyed) vision for an accurate level of depth perception. The visual distortion caused by astigmatism can also affect your depth perception.
What are some of the problems people experience when watching 3D movies?
Some viewers commonly experience headaches, nausea and dizziness while trying to 3D, but these symptoms are temporary. "When we are looking at the natural world, the eyes, the muscles in the eyes that allow us to focus, and the muscles that move the eye work in tandem," he said.
