You really should seek medical treatment immediately! Do not wait. Call 911, they will walk you through what to do. You pay for them anyhow.
Seriously (this goes for anyone), any time you get a chemical (paint, thinner, GAS,...) in your eyes, you need to flush a minimum of 15 minutes with water. You probably do not have an eyewash station in you home, so the water hose is probably the best bet. The water needs to be flowing a constant rate near the rate of a drinking fountain. It is going to hurt, but you must keep doing this for 15 minutes. DO NOT STOP for 15 minutes!!! It would be best to get someone to call for medical assistance at the same time, or get some one to take you to the doctor immediately!
Your eyes are not something to take chances with. It would be a serious bummer to have a car that you could not drive or see.
