Most bumps on the eyelid are styes. A stye is an inflamed oil gland on the edge of your eyelid, where the lash meets the lid. It appears as a red, swollen bump that looks like a pimple. It is often tender to the touch.
Bump on the eyelid; Stye; Hordeolum
A stye is caused by bacteria from the skin that get into the oil glands in the eyelids that provide lubrication to the tear film. Styes are a lot like common acne pimples that occur elsewhere on the skin. You may have more than one stye at the same time.
Styes most often develop over a few days and may drain and heal on their own. A stye can become a chalazion -- this is when an inflamed oil gland becomes fully blocked. If a chalazion gets large enough, it can cause trouble with your vision.
If you have blepharitis (see eye redness), you are more likely to get styes.
