Blind as a Bat

[deckardcanine]

Do people still use the phrase “blind as a bat”?
I hope not; we ought to know better than that.
Although they have echolocation for aid
In discerning the things they should reach or evade,
The flying insectivores often prefer
To rely on the visuals (not just a blur).
The fruit bats depend even more on their eyes,
Since their ears aren’t as good as the bug-eating guys’.
They tend to be colorblind; nevertheless,
The palettes some see leave me truly impressed.
A few see UV light. It’s also been said
That vampire bats can detect infrared.
In general, bats see no worse in the day
Than at night. Now I hope that the myth goes away.
