… and don't have eyes!

Yes. Light receptors maybe, but eyes...

source

... and light-sensing organs called ocelli, which can sense the presence and absence of light. Additionally, some jellyfish have sensory structures called rhopalia, which contain receptors to detect light, chemicals and movement.

Oh wait! This is unexpected:

... One group of jellyfish, the cubozoan jellyfish, have complex eyes... with lenses, corneas and retinas in their rhopalia.

Huh. Wiki agrees:

box jellyfish are unique in the possession of true eyes, complete with retinas, corneas and lenses.[13] Their eyes are set in clusters at the ends of sensory structures called rhopalia

Whoa.
