Why do two eyes give better vision than one?
1 Because two lenses together impart a higher converging
power so that a
sharp image is formed on the retina
2 Because two eyes do not form exactly similar images and
the fusion of
these two dissimilar images in the brain gives the three
dimensional or
stereoscopic vision
3 Because both the eyes are connected by nerves to the brain
and hence
transmit the message more quickly to the brain
4 None of these
