Many People Can Not Enjoy The Spectacle of 3D Films Because of Vision Problem
A lack of coordination of the eyes causes dizziness, fatigue, double vision in these people. You can correct this deficiency. These vision problems, the impact many times in the distance control can also affect driving.
Many people can not enjoy the spectacle of 3D films due to a deficiency of binocular vision, lack of coordination of the eyes, which can cause these viewers dizziness, fatigue and double vision.
Binocular alteration is not attributable to the three-dimensional visual technology (which has proliferated in other media like movies and video game consoles) and in many cases can be corrected with a single step by the optical, to correct the most common dysfunction, such as the called fixation disparity (the eyes do not look the same point), but in other cases it is necessary to resort to ophthalmologist or other specialist.
If we see that a child shows no sign of surprise or enthusiasm for 3D effects, does not move his arms or try to play what ’sale’ of the screen is that you may have a deficit binocular
Binocular vision is a shared vision and eye coordination, by which images reach the brain and are combined yielding a three dimensional image, but if one of the two eyes do not work properly, or does so with a different visual acuity, by the wrong power to prevent this merger and disappears 3D or stereoscopic perception.
3D films are thus a way to detect such problems and tackle them early, because the binocular vision is essential to control the distance (eg driving overtaking), cycling and avoid obstacles.
Once problems are identified we need to go to the optician, because it can be corrected through glasses with prismatic lenses that help to coordinate vision, vision therapy or with an ergonomic change when put in front screen.
In cases of strabismus or ambiopía (lazy eye) can not compensate for these defects, so the 3D view is impossible to achieve.
Other signs used to warn of a binocular impairment in children is a poor school performance, difficulty in calculating distances to stare fatigue, pain in the sides of the eyes, get you out of the spaces set by coloring, reading distance very short, lack of reading comprehension and concentration, or close one eye to stare.
