A stye is typically a small, red bump located at the edge of your eyelid. This is usually caused by bacteria and is categorized as an infection of the eyelid. Styes may look like a pimple or boil and are filled with pus. Although styes begin to disappear on their own after a few days, you may want to contact an eye care professional if discomfort persists.
