Just gonna put a fun fact here, bats aren't even blind. :3 The phrase "As blind as a bat" is short for "As blind as a bat at noon." Their eyes are just very sensitive to light.

It's kinda like how the phrase "Sure as sugar" is short for "As sure as sugar is sugar." Phrases just get shortened over time.
