My vet recommends cold chamomile tea. Not tried it myself
Discussion
Its an inflamation so that makes sense. I can imagine it wont hurt your eyes either, like perhaps other stuff would.
I'd try it Pablo, atleast if you can find chamomile (would avoid teabags with other stuff in it as well). Make sure there are no solids in the water. A good strong tea, and then diluted with water 1:1 should work. Its a bit of a hassle, but try to get your eyes in a bowl, and move your eyes submerges around for 3~5 minutes.
Or....get some eyedroples from a pharmacy😅🤷♂️
