Last year I had an accident that grounded me from flying for about 3 months. I was getting my flight box out of the car and accidently bumped the fuel pump (glow fuel) switch on my flight box to the "ON" position. I have a good pump and the full stream hit me square in the left eye.
The pain was so intense I had trouble getting from the garage into the house to get help. My wife called my eye doctor right away and they said to flush the eye with cold water for 15 minutes and then get to his office.

First the doctor deadened my eye to stop the pain and then he flushed some more with about a quart of fluid. His exam then revealed the fuel had burned off the outside layer of the cornea. He then said the good news was I should fully recovery my eye sight but it would be very painfull for a couple of days. After 3 months I was back to 20-20 on the vision test.

I never leave the fuel pump nozzle pointing straight up any more. Safety glasses during all modeling activities are a very good idea.
