brain also has to handle putting those two images together, causing it
to do extra work, also sacrificing visual field. However, if you use
one eye, there is no set interpretation caused by stereoscopic vision
(triangulation) from two eyes, leaving the interpretation of distance
up to the brain (that means you!) so the image can to you be as far
away or as close as you interpret it to be, and can even seem 3d. The
only bio-physical factor which cues your mind to distance in this case
is the focus of your pupil, meaning that watching a movie too close to
the screen will still strain your eyes. Also using one eye in a dark
environment may even allow your field of vision to completely fill the
entire area of the screen, (it is a feeling like that the screen is the
only thing that exists, normally you need drugs for this feeling). This
is also due to the fact that your mind only has to interpret one image
from one eye, (its 2d anyways, you don't need two copies of the same
image) allowing your brain to put more processing on that image, and
therefore extending the visual field. |
