What Is a Stye?

A stye is a small, red bump that forms on the eyelid, often looking like a pimple. It happens when an oil gland at the base of an eyelash becomes blocked and infected. Styes are common and usually harmless, though they can be painful or irritating. Most heal on their own, but some may need simple treatment to speed recovery.

What Causes a Stye?

Styes develop when bacteria, often Staphylococcus aureus, infect the oil glands of the eyelid. Poor eyelid hygiene, rubbing the eyes with dirty hands, or leaving makeup on overnight can increase the risk. People with conditions like blepharitis or rosacea are also more prone to them. In most cases, styes are short-term and not linked to serious eye problems.

What Are the Symptoms of a Stye?

A stye usually begins with mild discomfort on the eyelid before turning into a red bump. Common symptoms include:

  • Swelling and redness on or near the eyelid
  • Tenderness or pain in the affected area
  • A small yellow spot that may drain pus
  • Watery eyes or sensitivity to light
  • A feeling of something stuck in the eye

How Is a Stye Diagnosed?

Most styes can be diagnosed through a simple eye exam. An eye doctor will look at the eyelid closely to check for swelling, tenderness, and blockage of the oil gland. Additional tests are rarely needed unless there are repeated styes or other complications. Diagnosis is straightforward and usually does not require lab testing.

How Is a Stye Treated?

In most cases, a stye clears up within a week. Warm compresses applied several times a day can help drain the pus and relieve discomfort. Over-the-counter pain relievers may ease soreness, while antibiotic ointments or drops are used only if the infection is severe. Rarely, a doctor may drain a large stye if it does not improve. Good eyelid hygiene helps prevent future styes.

When Should You See an Eye Doctor for A Stye?

If a stye doesn't improve within a week or causes severe pain and swelling, visit your eye doctor. Recurrent or persistent styes could signal underlying conditions such as chronic blepharitis or gland blockages.

Regular eye exams are one of the best ways to detect and manage eye diseases early. Many eye conditions develop gradually and may not show noticeable symptoms until they start affecting vision. Visiting an eye doctor routinely helps protect your eyesight and maintain good eye health over time.

Frequently Asked Questions

Can You Pop a Stye?

It is best not to pop a stye because squeezing can push bacteria deeper into the eyelid and make swelling worse. It can also spread the infection to nearby glands or irritate the eye surface. Warm compresses are a safer way to help it drain naturally.

How Long Does a Stye Usually Last?

Many styes improve within a few days and clear up in about a week. Warm compresses done consistently can shorten the time and ease tenderness. If it keeps getting bigger or does not improve after about a week, it is safer to get checked.

Can You Wear Contact Lenses or Makeup With a Stye?

It is better to avoid contact lenses and eye makeup until the stye heals. Contacts and makeup can trap bacteria, slow healing, and raise the chance of spreading infection. Switch to glasses, throw out old eye makeup, and clean tools well before using them again.

How Can You Prevent Styes From Coming Back?

Good eyelid hygiene helps lower the risk, especially if you tend to get recurrent styes. Washing your hands, removing makeup before bed, and cleaning the eyelid margins can reduce bacteria and oil buildup. If you have blepharitis or rosacea, managing that condition can also help prevent repeat flare-ups.
