I understand the two points of vision creates depth perception but using energy to focus with two eyes puts strain on my brain. Could we live with just 1 effectively?
In: Biology
The best experiment you can do to find out first hand why we have or at least how we benefit from having two eyes, is as follows.
1. Hold one eye close or cover it with a patch.
2. Go for a jog in a forest
You’ll get a quick lesson in the value of depth perception, peripheral vision and field of vision.
All are impaired by having only one eye.
