Bat Eyes Vs. Human Eyes

Differences between

bat species.

Size

Bat's eye size depends on what species it is. Microbats, the most common of bats, have small eyes.

Megabats on the other hand have bigger eyes.

Echolocation

Most bats have echolocation, but some have are more specialized to use it better. Microbats use echolocation more, to use for hunting. Megabats eat fruit an such, so it's not as needed. But the range of use for echolocation is short.

Climate

Each type of bat lives in a different climate. The larger fruit bats, Megabats, live in warmer climates, and more open-like habitat. The smaller bats, Microbats, live in cooler climates, while their habitat is cramped.

Humans

Sight

Humans don't have echolocation, so we rely entirely on our eyesight to see, while bats have two ways of seeing. Our eyes have many rods and cones to help see colour and the difference in lighting.

Climate

Our climate doesn't affect our eyes too much, except for if it's too bright. That could lead to eye damage from the sun's UV rays.

Compare

Shape

Depending on the bat, their cornea will be flatter than humans. This results in poorer vision, and is mainly seen in microbats.

Cones & Rods

Unlike humans bats have less cones, and more rods. Meaning their eyes can catch 50% more light than us humans. They can see better in the dark, which is helpful because they are nocturnal and avoid bright places. Because it could damage their eyes easier, because they're more sensitive to light.

Vision

Microbats have horrible vision compared to us humans, while megabats can have better eyesight. We both rely on them for communication and seeing each other it wouldn't make sense for bats to be born blind-unless it's a condition of course.
