3D stereoscopic technology is coming back in vogue with a vengeance. Still, while certain 3D effects have an impressive visual effect, eyestrain is reported by some and it appears that it may be because of poor binocular vision, which the Eyecare Trust says affects six million British people.
3D technology relies on our eyes ability to work together as a co-ordinated team to achieve an accurate perception of depth, reads a release by the company. However, more than one in ten of us (12 percent) has a visual impairment that means our brains are unable to correctly process the individual images that are transmitted to it via our left and right eyes. This leads to an inconsistency in viewing the three spatial dimensions (height, width and depth) required to enjoy 3-D films in all their glory.
You may not have realized that you have poor binocular vision before because your brain will often try to compensate for any visual inadequacies, continues the release. If left untreated binocular disorders such as amblyopia can affect your ability to read well and result in a greater propensity to suffer from screen fatigue when working at a VDU or watching TV for long periods of time.
Binocular conditions can be detected during eye exams, and treatment is possible. The Eyecare Trust recommends everyone who hasn’t had a recent vision test to do so if they’re experiencing problems with 3D images.
