why do we have two eyes instead of one eye |
|
Answer» It gives a wider field of view .a human being has a horizontal fields of view of about150 with one eye and about180 with two eye.example of pencil , we can\'t meet the nips of pencil with one eye. The problem of parallax error in vision is reduced a lot because of this double eye vision. It also enhances our depth perception giving us a very good evolutionary advantage.Our ability to detect faint objects is more distinct.Humans are able to enjoy stereoscopic vision. Some animals with two eyes like rabbits and buffaloes have 360 degree field of vision but they do not have stereoscopic vision. This is an advantage only available to animals with two eyes in the front of their head like us humans. |
