Amazon Doesn't Understand Lord of the Rings

[@LaffeeTaffeeGG]

Has the show ever actually said what the rings are for, or what the rings actually do? It kind of just seems like they really really really want to put the rings on because the rings will save the Elves... but they don't seem to explain why it's necessary to risk Sauron's corruption so they can wear the rings. It feels extremely forced and almost like the studio doesn't even know what the rings do, so they're just saying "they need to wear them for reasons! Shutup dumb mortals, enough of your logical questions!"
