Seeing 3D movies can increase rating of symptoms of nausea, oculomotor and disorientation, especially in women with susceptible visual-vestibular system. Headaches, blurred vision and general vision discomfort are presented in subjects who have this condition and are exposed to 3D effects. When the inability to focus objects from varying distances is presented. Convergence insufficiency ĭisorder in which the subject finds it difficult to keep both eyes aligned with each other, causing asthenopia. It occurs when a single eye sends input to the brain while ignoring inputs from the other eye. Amblyopia Īmblyopia, commonly known as “lazy eye”. Eyes aren't properly aligned and so the input the brain has to render is in mismatch, preventing correct 3D stereoscopic perception from happening. Strabismus is the lack of binocular vision. Myopia (nearsightedness), hyperopia (farsightedness) or astigmatism. Symptoms sign that an eye condition is present, which may be: These problems may also reflect upon a fundamental vision-related problem not entirely linked to binocular vision issues. Watching shows and/or movies in 3D can help to point out those problems earlier, working as a screening check and noticing the lack of binocular vision so that a proper treatment can be applied. If an individual lacks binocular vision, then a 3D perspective is impossible and simply unachievable. This is due to the test's requirement for the eyes to work coordinated with the brain in order to render a 3D image.Īccording to the American Optometric Association there are approximately from 3 to 9 million people with binocular vision problems. Nowadays a great array of optometrists have opted to use 3D presentations and therapies to measure eyesight accuracy. Īdverse health effects, such as oculomotor symptoms, motor disorientation, and visual fatigue on viewers after three-dimensional exposure, result from the mismatch between the visual, the proprioceptive and the vestibular stimuli. One may counter vergence-accommodation conflict when seeing a 3D movie or using a near-eye display system (e.g., augmented reality (AR) and virtual reality (VR)) adapting stereoscopic stimuli without registration function. Īn increase in vergence-accommodation conflict occurs as the eye changes its movement patterns to focus on the position of objects recreated by stereoscopy. The viewing of 3D stereoscopic stimuli can cause symptoms related to vision disorders that the individual already had, as a person with a healthy binocular vision shouldn't experience any side effects under three-dimensional exposure.
