Itchy, irritated, red, goopy eyes -- all signs of pinkeye.
Usually one of two things is to blame: A virus or bacteria.
Viral pinkeye: Red, irritated eyes. Watery discharge. May feel gritty. Lasts 3-5 days. Relieve itch and irritation with over-the-counter eyedrops.
Bacterial pinkeye: Red, irritated eyes. Thick, yellow-green discharge. May be crusted closed when you wake up. You can treat it with antibotics.
Both are really contagious. Wash your hands each time you touch your face.
