A stye is a condition in which oil glands in your eye lids become inflammed forming a painful lump containing pus. Styes are usually caused by bacterial infections of an oil gland, often at the base of an eyelash follicle.

The most common symptoms of a stye include itching sensation, sensitivity to light, tenderness of the eyelid, swelling, redness and tearing of the eye. Styes generally do not require any treatment and heal on their own over time. Styes on the outside of the eyelid turn yellow and release pus and heal faster. However, internal styes may take slightly longer to heal. You can warm compresses over your eyes to help release the pus, but it is important not to press on them.

If the stye is caused due to an infection, your doctor may prescribe antibiotics. Do not attempt to burst or drain the stye, and refrain from wearing contact lens and makeup until healing has occurred. Styes can be prevented by taking extra care of your eyelids to avoid accumulation of germs and bacteria.
