Red Eye Stye: What You Should Know

A stye develops when an eyelid oil gland or lash follicle becomes blocked and inflamed. You may notice a small painful bump at the eyelid edge, tenderness when blinking, mild swelling, watering, or a gritty feeling. The redness is often strongest around the lump rather than spread evenly across the whole eye. A stye is different from conjunctivitis, which commonly causes redness across the eye surface and discharge. Allergic conjunctivitis more often brings itching and watering in both eyes. A red eye can have other causes, so the pattern of symptoms matters.

Place a clean, comfortably warm compress over the closed eyelid for several minutes, repeating this through the day. Wash your hands before and after touching the area, and avoid squeezing or popping the lump. Pause eye makeup and contact lenses until the eyelid feels well and the eye is no longer irritated. Do not share towels, cosmetics, or eye drops. A pharmacist or clinician can advise whether a suitable treatment is needed, especially if swelling extends beyond the eyelid or the lump does not settle.

Arrange prompt medical assessment for severe pain, marked swelling, light sensitivity, blurred or reduced vision, pain when moving the eye, fever, or redness spreading around the eye. Seek urgent help if an injury or chemical exposure caused the redness. Contact an eye professional when a stye keeps returning, leaves a persistent lump, or has not improved with gentle care.

Could this be a stye or another eyelid problem? Is the redness limited to the eyelid area? What should I use if I wear contact lenses? What changes would mean I need an urgent eye examination?
