Well, don't worry, we will get foreign things into the eyes occasionally. In case of a bit of hot pepper in your eyes, you may feel irritated and painful. You eyes keep watering and burning at the first one hour. The first thing you need to do is to rinse your eyes through out the rest of the day trying to wash it out with vinegar or milk. This can help the veins dilated and increase the blood flow and produce more tears to take away the pepper. Do not flush with the water as the pepper is not soluable in water. If all your endeavors are in vain, you can also try Visine, vegetable oil or just head to your doctor.
