The ability to perceive depth in a 3D presentation turns out to be a highly sensitive test of a range of vision health indicators and much more sensitive than the standard eye chart that has been in use for 150 years. This is because 3D viewing requires that both eyes function in a coordinated manner, as they converge, focus and track the 3D image.

If you are not able to perceive images in 3D, it most likely means that you have a problem with binocular vision, or using both eyes together.
