A stye is totally different from pink eye. They are two different kinds of eye problems. A stye refers to acute infection and inflammation of the secretory glands in eyelids. In most cases, the glands are infected by bacteria and so they are clogged for inflammation. Because of the less production of tear film, patients with a stye would have eye dryness. At the same time, because the secretion built up inside the glands, a bump would formed, red, itching and painful, sometimes with yellow or white point at the top. The bump usually locates at the root of eyelashes. As to pink eye, it is the infection and inflammation of conjunctiva, which is a clear and transparent covering on eyes. With conjunctivitis, people would develop increased sensitivity to light, strong foreign body sensation, watery and red eyes, and swelling eyelids. Both conjunctivitis and a stye have similar symptoms, but there is no bump on eyelids for patients with conjunctivitis. In both cases, warm compress could help.
