Submit your own QuestionPink eye, also called conjunctivitis, is one of the most common eye conditions in women of all ages. It can feel uncomfortable, look alarming, and sometimes spread quickly — but in most cases, it's treatable and not dangerous.
Still, some forms of pink eye need medical care, and a few rare causes can threaten vision if ignored. Knowing the difference matters.
This guide explains what pink eye is, the symptoms to watch for, how to find relief, and when to speak to a doctor.
Pink eye is inflammation of the conjunctiva — the thin, clear tissue that covers the white of your eye and the inside of your eyelids. When this tissue becomes irritated or infected, tiny blood vessels swell, making the eye look pink or red.
Pink eye can affect one or both eyes.
There are several types of pink eye, and the cause determines how it should be treated.
Women who wear contact lenses, use eye makeup, or have seasonal allergies may be at higher risk.
The most common symptom of pink eye is eye redness — but there are other signs to look for.

Doctors usually diagnose pink eye with a simple eye exam. They may:
In rare or severe cases, a sample of discharge may be tested to identify the exact cause.
Treatment depends on the cause.
There's no specific cure. The virus must run its course.
You can:

A doctor may prescribe:
Most people improve within a few days of starting treatment.
Avoid wearing contact lenses until fully healed.
Treatment focuses on calming inflammation.
Options include:
If allergies are frequent, speaking to a healthcare provider about prevention can help.
Regardless of cause, these strategies may ease discomfort:
Do not share eye drops, makeup, or towels — pink eye can spread easily.
If you wear contacts:
Contact lens users have a slightly higher risk of serious corneal infections. If pain or blurred vision develops, seek medical care quickly.
Viral and bacterial pink eye are contagious.
You can spread it through:
You're typically contagious while symptoms are active — especially if discharge is present.
To reduce spread:
Allergic and irritant-related pink eye are not contagious.
If symptoms last longer than two weeks or worsen, speak to a doctor.
Pink eye during pregnancy is usually not dangerous, but it should still be evaluated before using medications. Many eye drops are safe, but treatment decisions should always be discussed with a healthcare provider.
Prevention focuses on hygiene and awareness.
Small habits make a big difference.
While most cases of pink eye are mild, you should speak to a doctor if:
Any symptom involving sudden vision loss, severe pain, or neurological symptoms (like severe headache and nausea) should be treated as urgent.
When in doubt, it's always safest to speak to a doctor.
Pink eye is common, uncomfortable, and usually temporary. Most cases resolve with simple care and time. However, not all eye redness is harmless.
Understanding the type of pink eye you may have — viral, bacterial, allergic, or irritant-related — helps guide the right next steps.
