What should you know about what a stye is?

A stye, medically called a hordeolum, is a localised area of inflammation at the eyelid edge or within the lid. It may look like a small red pimple near the lashes, or it may be hidden on the inner surface. Tenderness, swelling, watering, crusting, and discomfort with blinking are common ways it can be noticed. Some styes develop a pale centre as fluid collects.

A chalazion is a different type of eyelid lump caused by a blocked oil gland and is often firmer and less tender. Broad eye redness, discharge, or a change in vision may indicate another issue, so symptoms should be considered together rather than labelled automatically.

Use a clean warm compress on the closed eyelid for several minutes, repeating through the day. Keep the temperature comfortable and avoid rubbing. Clean hands matter before and after touching the face, especially if there is crusting around the lashes.

Do not squeeze, pierce, or share towels, cosmetics, or eye products. Stop contact lenses and eye makeup until the irritation has settled. If you need help confirming what the lump is, book a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/).

Seek prompt care if swelling spreads beyond the eyelid, fever occurs, pain is severe, vision is reduced, or eye movement hurts. Sudden symptoms after an injury also need medical attention.

Arrange a review for a recurrent or persistent lump, ongoing [Red Eye](/symptoms/red-eye/), or [Eye Discharge](/symptoms/eye-discharge/) that does not settle. An examination can distinguish a stye from other causes of eyelid or eye symptoms.

Ask whether the lump is a stye or a blocked gland, how to clean the lid safely, and what symptoms should prompt faster care. Tell the clinician about contact lenses, repeated episodes, skin problems, discharge, and visual changes.
