The first step is to relax. It should not be a very big problem. Don’t panic. The latex paint is water based paint, it is easier to be washed out. Use running water to flush your eyes for several minutes, until the paint has been washed out. The blood shots in eyes and watering eyes are inevitable. Apply some compress over your eyes if it makes you more comfortable. Usually these uncomfortable feelings would go away in a few minutes. Usually tears and the water could help to get paint out of your eyes. Blink more frequent than normal, let the tears in eyes help to rinse and lubricate eyes, which can relieve these symptoms too. Don’t worry too much. If you keep feel burning in eyes, blurry or cloudy vision, or even get high temperature without any clue, it is better for you to visit your doctor at once to avoid any chemical burns caused by the paint.
