What Is a Stye?
A stye is a small, painful bump that forms along the eyelid. It develops when an oil gland near the eyelashes becomes blocked or infected. Certain habits and health conditions can increase the chance of developing one.
Risk factors include:
- Touching the eyes with unwashed hands
- Wearing contact lenses without proper cleaning
- Using old eye makeup
- Chronic eyelid irritation
- Skin conditions such as rosacea
- Diabetes
Styes can form on the outside or inside of the eyelid. While they can be uncomfortable, most styes are mild and improve with simple home care.
Symptoms
A stye often starts as a sore or swollen spot near the eyelashes. Symptoms may become more noticeable over a day or two.
Common symptoms include:
- A red bump on the eyelid
- Swelling or tenderness
- Eye irritation or discomfort
- Watery eyes
- Crusting around the eyelid
- Feeling like something is stuck in the eye
- Sensitivity to light
How Is It Diagnosed?
Healthcare providers usually diagnose a stye by examining the eyelid and reviewing symptoms. Testing is rarely needed.
If styes keep returning or do not improve, your provider may look for underlying conditions affecting the eyelids or skin.
How Is It Treated?
Many styes heal on their own within one to two weeks.
Home treatment may include:
- Applying a warm compress several times a day
- Keeping the eyelid clean
- Washing hands often
- Avoiding eye makeup and contact lenses until healed
- Not squeezing or picking at the bump
In some cases, providers may recommend antibiotic ointment. If the stye becomes severe or does not improve, an eye specialist may provide additional treatment.
