Ive had welder flash more time than i want to rememeber. Im giving you my solution for it. I think i tried it all and by far this works the best for me. When i wake up in the middle of the night, and it doesnt' take long for me to realize what i have. (Gasoline and Sand in my eyes) Ill take a small raw potato, cut it in half, and place the cut edges against my eyelids, then tie a washcloth, towel, sock, whatever to hold them there. The coolness helps to take away the pain, and the potato does something to relubicate my eyes. It usually takes me about an hour to fall back asleep, but my eyes feel alot better in the AM.
Ive tried Visine, and next to a late night trip to the ER, this is the best remidy ivy found.
