Styes & chalazia

A stye or a chalazion is a small lump on the eyelid. They're common, usually harmless, and often settle with simple home care — but a lump that won't go, keeps coming back, or looks unusual is worth having checked.

What it is

A stye is a tender, red lump at the edge of the eyelid, caused by a blocked, infected gland — a bit like a spot. A chalazion is a firmer, usually painless lump a little further from the lid margin, caused by a blocked oil gland.

Both are linked to the eyelid's oil glands, and people prone to blepharitis or dry eye tend to get them more often.

What you might notice

  • A red, tender lump at the edge of the lid (stye)
  • A firmer, painless lump within the lid (chalazion)
  • A swollen, heavy-feeling eyelid
  • Watering or mild irritation
  • Occasionally, blurred vision if the lump presses on the eye

Recognise these? Book a consultation and we'll help you get to the bottom of it.

What causes it

Blocked or infected oil glands in the eyelid.

More common in people with blepharitis, dry eye or the skin condition rosacea.

How we help

Most styes and chalazia settle with warm compresses over a week or two. If a chalazion is stubborn, large or keeps returning, Dr Leong can advise on treatment, including a minor procedure to drain it.

A lump that grows, keeps recurring in the same spot, or looks unusual should always be checked, to be sure of the diagnosis.

Common questions

Should I pop a stye?
No — squeezing or popping can spread the infection and make it worse. Warm compresses are the safe way to help it settle; if it won't clear, have it checked.
What's the difference between a stye and a chalazion?
A stye is a tender, red, infected lump at the lash line. A chalazion is a firmer, usually painless lump a bit further into the lid, from a blocked oil gland. They're treated slightly differently.
How long does a chalazion take to go?
Often a couple of weeks with warm compresses, though some take longer. A stubborn or large chalazion can be treated in the clinic if it doesn't settle on its own.
When should I see someone about an eyelid lump?
If it's growing, keeps coming back in the same place, affects your vision, or looks unusual, have it checked — it's worth confirming the diagnosis.
