Why would they need eye drops? They are submerged in salty water.

Yes. Light receptors maybe, but eyes…
… 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.

It was an eyedrop that used a protein or something from jellyfish, that affected human eyes to temporarily see better in low light. Been years since I’ve heard anything about it. Another sensationalized “breakthrough” I guess.

So, the articles are old, but chlorin e6 mixed with insulin and DMSO in saline gives a temporary boost to nightvision.
Sounds fucking awesome, and the ingredients all seem fairly easy to acquire. No commercial product, but why would there be?
