Too much video game playing may cause vision problems. [11] Extensive viewing of the screen can cause eye strain, as the cornea, pupil, and iris are not intended for mass viewing sessions of electronic devices. Using video games for too long may also cause headaches, dizziness, and chances of vomiting from focusing on a screen.
A sudden onset of depression later in life can also be a warning sign of dementia, according to the Alzheimer’s Association, which notes that up to 40 percent of people with Alzheimer’s ...
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.
As with video games, rapidly changing images or highly regular patterns such as flashing banner ads or irregular fonts can trigger seizures in people with photosensitive epilepsy. Two sets of guidelines exist to help web designers produce content that is safe for people with photosensitive epilepsy:
Sometimes, a condition can't be helped with medication. Refractive errors, some of the most common types of vision problems, cannot be treated with medication, for example. Instead, glasses ...
A page or photograph which shows the same image twice, but slightly displaced–from a printing mishap, a camera moving during the shot, etc.–can cause eye strain due to the brain misinterpreting the image fault as diplopia and reacting by adjusting the sideways movements of the two eyeballs, in an attempt to fuse the two images into one.
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. [5] These problems may also reflect upon a fundamental vision-related problem not entirely linked to binocular vision issues.
Virtual reality sickness may have undesirable consequences beyond the sickness itself. For example, Crowley (1987) argued that flight simulator sickness could discourage pilots from using flight simulators, reduce the efficiency of training through distraction and the encouragement of adaptive behaviors that are unfavorable for performance, compromise ground safety or flight safety when sick ...
