This is due to the test's requirement for the eyes to work coordinated with the brain in order to render a 3D image. According to the American Optometric Association there are approximately from 3 to 9 million people with binocular vision problems. If an individual lacks binocular vision, then a 3D perspective is impossible and simply unachievable.
Computer vision syndrome (CVS) is a condition resulting from focusing the eyes on a computer or other display device for protracted, uninterrupted periods of time and the eye's muscles being unable to recover from the constant tension required to maintain focus on a close object.
The resulting perception is also known as vision, sight, or eyesight (adjectives visual, optical, and ocular, respectively). The various physiological components involved in vision are referred to collectively as the visual system , and are the focus of much research in linguistics , psychology , cognitive science , neuroscience , and molecular ...
The experience of eye strain when reading in dim light has given rise to the common misconception that such an activity causes permanent eye damage.

This was shown in a study in which stereoblind subjects were posed with the task of judging the ...
The Worth Four Light Test, also known as the Worth's four dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision.
