From Television to Video Games to classrooms, 3D video content seems to be everywhere these days. Three-dimensional, or 3D technology enhances the viewers experience, whether in a movie theatre or watching a smart TV, the technology is becoming more easily adaptable to a wide array of devices.
This leads us to question, how does a person actually see 3D? Binocular vision incorporates both eyes simultaneously, with the slight difference between the two images creates disparity between eye images and the brain interprets this as depth. The viewer wears a pair of 3D glasses will special filters that allows the two streoimages to be seen by each eye seperately. The brain is able to filter the images and fuse the picture, which creates the unique 3D experience.
Unfortunately, not everyone has the depth perception ability to view 3D content. In fact, about 2 out of 10 people are unable to view 3D entertainment. The viewer may experience dizziness, discomfort, and lack of depth. These symptoms the person experiences is many times related to an eye muscle imbalance, refractive problem, lack of binocular vision, focusing difficulaties, and lazy eye. The eyestrain and fatigue cause the image to be unbearable, and thus the person cannot view the experience.
These symptoms are a sign of a potential vision problems. The problem can be accurately evaluated and diagnosed by visiting your optometrist who is your eye doctor. Often times the refractive error or muscle imbalance can be corrected with prescription spectacle lenses, allowing the patient to experience 3D technology.
