the.com/cornea

the only part of you that breathes air directly and refuses any blood.

means The clear, dome-shaped front layer of the eye that covers the iris and pupil and bends incoming light so you can see.

from From Latin cornea, short for cornea tela, 'horny tissue' — from cornu, 'horn.' The same cornu gives us 'unicorn,' 'cornucopia,' and 'cornet'; ancient anatomists thought this tough, translucent layer resembled thin shavings of horn, the kind once used for lantern windows. So the eye's window was named for the stuff old lanterns were made of.
