Completely random pjo/greek mythology thought since the cyclops (I don’t remember his name but I should) had the Golden Fleece in theory couldn’t he have used it to heal his eye?
@glimmerfish so I had thought of this same thing a few months back and I searched what could possibly be the answer and which is found was polyphemus was very stupid overall and was very easily tricked, so it didn't occur to him to heal himself
