What is the best home remedy for welders flash burn?

Ok before you say it, going to the eye doctor is out of the question. This is for my boyfriend and he WILL NOT GO. We already know all about it and what can happen. Yes I know its stupid, but there’s nothing I can do. We don’t have the money in any way to go to a professional anyways.

That being said. I hear alot about putting peeled potatoes on the closed eyes, I also heard that staring at a florescent light for 2 minutes after the flash will prevent “sandpaper eyes” at night. What other tips or remedies do you know of that will help him.

And again, going to the doctor wont happen and we already know all about the possibilities of not getting it treated by a doctor, so please don’t comment with an answer of that sort. I don’t mean to sound like a Bleep but I am only looking for things that we can do other than that.
