Your frame of reference is limited entirely to what you've experienced throughout your life. It's why many kids with binocular vision problems will attend a 3D movie but not see the true 3D effect. “In many cases, a child may still perceive depth, but not the true, vivid 3D,” said Dr.
Difficulties with 3D vision and depth perception could be due to an undiagnosed lazy eye. Stereopsis, more commonly known as 3D depth perception, occurs when your brain combines the two images received from each eye and creates one single 3D image.
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.
If you are unable to see the 3D effect at all, you may be stereo-blind, otherwise referred to as having monocular vision, being a flat-viewer or lacking depth perception.
Not everyone can see in depth, either with 3D movie glasses or even with their daily vision. The most common causes of not having depth perception (or stereopsis) are: 1) Blurry Vision: Refractive errors like myopia, astigmatism, and hyperopia can cause a blurry image to he brain which inhibits depth perception.
If you can't see movies in 3D, you aren't alone. Around 12 percent of the population struggles with depth perception, also known as stereoblindness.
Not every person can see the 3D illusion in autostereograms. Because autostereograms are constructed based on stereo vision, persons with a variety of visual impairments, even those affecting only one eye, are unable to see the three-dimensional images.
Your Eye Doctor Can Help With 3D Vision Issues
If you're experiencing difficulties with 3D vision, speak to your eye doctor about vision therapy. This doctor-prescribed, evidence-based regimen of in-office and at-home eye exercises helps reset and strengthen the connection between your eyes and your brain.
Visual Thinking
Many people with dyslexia often think in images as opposed to words, which is attributed to the unique activations in their brains. People with dyslexia are also more likely to form 3D spatial images in their minds than non-dyslexic people.
Causes of Poor Depth Perception
Crossed eyes are a sign of strabismus. Another factor is amblyopia or lazy eye, which occurs when the brain function favors one eye. This results in one eye failing to track properly. Trauma to the eye, blurry vision and nerve problems can also cause poor depth perception.
At about 5 months, he starts to develop his 3D vision. He distinguishes shades and is able to carefully examine an object in his hands. At around 6 months, he starts to perceive distances.

Often called “3D Vision,” depth perception is dependent on the ability to use both eyes together at the highest level. 3D vision relies on both eyes working together to accurately focus on the same point in space. The brain is then able to interpret the image the each eye sees to create your perception of depth.
A child with vision loss might:
squint the eyes or frown. complain that things are blurry or hard to see. have trouble reading or doing other close-up work, or hold objects close to eyes in order to see. blink more than usual or seem cranky when doing close-up work (such as looking at books)
Watch for Eye Problems
Schedule an eye exam for your child if you see signs of an eye problem, like if your child's eyes: Look crossed. Turn outwards. Don't focus together.
DYSLEXIC'S 2-D vs 3-D PROCESS
Dyslexic learners are “picture thinkers,” but more specifically, they are “three-dimensional picture thinkers.” They hold the ability to run a movie in their mind most of the time.
Around age 5 or 6 years, when kids begin learning to read, dyslexia symptoms become more apparent. Children who are at risk of reading disabilities can be identified in kindergarten. There is no standardized test for dyslexia, so your child's doctor will work with you to evaluate their symptoms.
In fact, despite reading ability, people who have dyslexia can have a range of intellectual ability. Most have average to above average IQs, and just like the general population, some have superior to very superior scores.
3D vision problems can indicate a serious eye disease.
3D vision is essential to hit or catch a ball or drive a car, and difficulties here could be due to undiagnosed vision problems. Stereopsis and 3D vision are necessary for driving and playing many sports, and contributes to a high quality of life.
As many as 20 percent of the population may not be able to fully see in three dimensions, said Dr. Kenneth J. Ciuffreda, a professor of optometry at the New York's State College of Optometry.
Typically, people with amblyopia also have little or no 3D vision, because it takes both eyes working together to provide depth of vision. "It looks flat and boring. If you ever try walking around with a patch over one eye, the world looks miserable," Hess said of having inadequate three-dimensional depth of field.
Humans can perceive depth when viewing with one eye, and even when viewing a two-dimensional picture of a three-dimensional scene. However, viewing a real scene with both eyes produces a more compelling three-dimensional experience of immersive space and tangible solid objects.
The right lens is polarized at a different angle than the left, so a different image gets through each lens. Polarized 3D is superior to anaglyph 3D because it doesn't make the film look dark and murky, and because it works for people who are colorblind!
An example of depth perception in normal life would be if someone is walking towards you, a person with accurate depth perception is able to tell when the person is about five feet away from them. However, someone with lacking depth perception is not able to accurately perceive how far away the person is.
