3D TVs

Conditions Which Prevent The Perception of 3D

Studies report that anywhere between 2 – 12% of the population are unable to experience the effects of 3D television. This is the result of one of various conditions predominantly including strabismus, amblyopia and optic nerve hypoplasia. Those who are physiologically unable to witness the effects of 3D are also referred to as being stereo-blind. This is the result of the eyes not being able to focus or align correctly. Looking to strabismus, and a variety of derogatory terms, the eyes do not fix upon locations at the expected angles, this in turn prevents the interpretation of the 3D effect implemented as it nullifies the key technology which causes the effect. In order for 3D to work the eyes need to work together as a precisely coordinated team, processing the pictures that are displayed to the left and right eye.

What Does This Mean?

So far manufacturers have been silent about stereo blindness, however, with such a large percentage of the population being isolated from the potential market questions must surely have been raised. In the meantime you be be reassured that all TV manufacturers look to stick to the rule of having a backwards button to turn off the 3D and revert back to 2D. However, for the 3d films and with the advent of the first glasses free 3D TV being released on the consumer market then surely questions will be asked and measures taken to prevent the exclusion of such a large group of individuals.

If you think you may have any of the conditions which cause stereo-blindness then we recommend that you go to your local opticians where a routine examination will usually detect any disorders you may have.  Also for more information on strabismus a look on this site to get more information  http://www.strabismus.org/
