Question

what is common in their eyes and our eyes​

Answer 1

The human eye belongs to a general group of eyes found in nature called "camera-type eyes." Just as a camera lens focuses light onto film, a structure in the eye called the cornea focuses light onto a light-sensitive membrane called the retina.

Answer 2

Explanation:

Your eyes contain 7 million cones which help you see colour and detail, as well as 100 million cells called rods which help you see better in the dark. In order to work well, cones need more light than rods. Rods cannot perceive colour, just black, white and gray.
