Pink Eye (Conjunctivitis)

Pink eye, also called conjunctivitis, is a problem with the thin, clear lining (the conjunctiva) that covers the inside of your eyelids and the white part of your eye. This lining has tiny blood vessels. When these vessels get swollen and inflamed, they become more noticeable, making your eyes look pink or red. This swelling can also cause a gritty feeling, itching, and sometimes a discharge that makes crusts form on your eyelashes overnight.

Pink eye is usually caused by a virus, but it can also be caused by bacteria, an allergy, or in babies, a problem with their tear ducts not being fully developed.

While pink eye can be uncomfortable, it usually doesn't hurt your eyesight. There are ways to treat the discomfort. Since pink eye is contagious, getting an early diagnosis and taking steps to avoid spreading it are important.

Pink eye, also known as conjunctivitis, is often recognized by several common symptoms. These typically affect one or both eyes.

A key sign is redness in the affected eye(s). It's like the whites of your eyes become inflamed and turn pink or red.

Another frequent symptom is itching. This can range from a mild tickle to a more intense, irritating itch.

You might also feel a gritty or sandy sensation in your eye(s), similar to having something small and irritating lodged there.

Often, a discharge, or fluid, builds up in the affected eye(s). This discharge can sometimes form a sticky crust overnight, which can make it hard to open your eyes in the morning.

Increased tearing, or excessive watering, is another possible symptom.

Finally, some people with pink eye experience photophobia, which means their eyes are sensitive to light. Bright light can feel painful or uncomfortable.

Red eyes can be a sign of serious eye problems. These problems might also cause discomfort, like a feeling of something being in your eye, blurry vision, or sensitivity to light. If you're experiencing any of these symptoms, it's important to get immediate medical attention.

If you wear contact lenses and notice any redness or other pink eye symptoms, you should immediately stop wearing your lenses. If your symptoms don't improve within a day or two, schedule a visit with your eye doctor. This is crucial to rule out more serious infections that could be linked to contact lens use.

Pink eye, also called conjunctivitis, has several causes. It's an inflammation of the thin, clear membrane lining the inside of your eyelids and covering the white part of your eye. Here's what can cause it:

Viral Infections: Many cases of pink eye are caused by a virus, often a type called adenovirus. Other viruses, like herpes simplex virus or chickenpox (varicella-zoster virus) can also cause it. Often, viral pink eye comes along with other cold-like symptoms, such as a runny nose or sore throat.

Bacterial Infections: Bacteria can also cause pink eye. This type can be spread easily, like the viral kind, through touching or sharing things. Using someone else's contact lenses without properly cleaning them is a common way to get bacterial pink eye.

Allergies: Sometimes, pink eye is a reaction to something you're allergic to, like pollen or dust. Your body's immune system overreacts to the allergen, releasing chemicals that irritate and inflame the eyes. This is called allergic conjunctivitis. Symptoms include itchy, watery eyes, and a runny nose. This type of pink eye is not contagious.

Chemical Irritants and Foreign Objects: If something irritating, like a chemical or a tiny piece of dust, gets in your eye, it can cause pink eye. Your eyes might water and produce mucus as they try to flush out the irritant. Most cases clear up on their own with a good rinse. But if the irritant is strong (like lye) or if the symptoms don't go away, see a doctor right away. A chemical burn or a small object stuck in your eye can cause serious damage.

Newborn Tear Duct Blockage: In babies, a blocked tear duct can sometimes cause pink eye.

How Pink Eye Spreads:

Both viral and bacterial pink eye are very contagious. They spread when you touch the infected person's eye, or something they've touched, and then touch your own eyes. The eye discharge itself is also a source of spread. Either one or both eyes can be affected.

Treating Pink Eye:

• Viral and bacterial pink eye: These infections usually clear up on their own. Your doctor might suggest antibiotic eye drops for bacterial pink eye or antiviral eye drops for viral pink eye.
• Allergic pink eye: Allergy eye drops and avoiding the allergen are often enough to manage it.
• Chemical or foreign object irritation: Rinsing your eye with clean water is usually enough. If symptoms don't improve or the irritant is strong, see a doctor immediately. They may need to remove the foreign object or treat any damage.

Important Note: If you have any concerns about pink eye, see a doctor. They can diagnose the cause and recommend the best treatment. Prompt treatment is especially important for chemical burns or if you suspect a foreign object is lodged in your eye.

Pink eye, also known as conjunctivitis, can be caused by a few things. One common cause is being around someone who already has pink eye, whether it's the viral or bacterial kind. Essentially, you're catching it from them, like a cold or the flu.

Another reason you might get pink eye is an allergy. If you come into contact with something you're allergic to, like pollen or pet dander, it can irritate your eye and cause allergic conjunctivitis. This type of pink eye is different from the viral or bacterial types and is often associated with other allergy symptoms.

Finally, using contact lenses, especially those you wear for a longer period, can increase your risk of getting pink eye. The extended wear of contact lenses can create a moist environment that bacteria or viruses can thrive in. Proper cleaning and hygiene practices when handling contact lenses are important to reduce the risk.

Pink eye, also known as conjunctivitis, can irritate the clear front part of your eye (the cornea). This irritation can sometimes affect how clearly you see. It's important to see a doctor right away if you have pink eye. Early diagnosis and treatment can help prevent problems down the road.

If you have pink eye, see your doctor if you experience any of these symptoms:

• Eye pain: This could be a sharp pain or a dull ache.
• Something in your eye feeling like it's stuck: This could be a scratch, a foreign object, or a feeling of irritation.
• Blurred vision: If your vision is unclear, it's important to get checked out.
• Sensitivity to light: If bright light makes your eyes hurt or feel uncomfortable, it's a good idea to see a doctor.

Pink eye, also called conjunctivitis, is easily spread, but it's not much more contagious than a common cold. To stop the spread, keep good hygiene habits.

Simple Steps to Prevent Pink Eye:

• Don't touch your eyes: This is a big one. Germs on your hands can easily get into your eyes.
• Wash your hands frequently: Wash your hands often, especially after touching your face, nose, or eyes. Use soap and water for at least 20 seconds.
• Clean your towels and washcloths daily: Germs can live on these items. Use a clean towel and washcloth every day.
• Don't share towels or washcloths: Sharing these items can spread germs.
• Change your pillowcases often: Pillowcases can collect germs, so change them regularly.
• Discard old eye makeup: Old mascara, eyeliner, and other eye makeup can harbor bacteria. Throw away old products.
• Don't share eye makeup or personal eye care items: This includes things like eye drops, eye patches, or anything that touches your eyes.

When to Stay Home:

It's usually okay to return to work, school, or daycare if you can maintain good hygiene and avoid close contact with others. However, if your job, school, or daycare requires close contact with lots of people, it's probably best to stay home until your symptoms clear up.

Pink Eye in Newborns:

Newborns are especially vulnerable to bacteria that can cause a serious form of pink eye called ophthalmia neonatorum. These bacteria can be present in the mother's birth canal, often without causing any problems for the mother. To prevent this serious infection, a special antibiotic ointment is applied to a newborn's eyes shortly after birth. This helps protect their eyes from infection.

Doctors usually diagnose pink eye by talking to you about your symptoms and looking at your eyes. This is enough for most cases.

Sometimes, your doctor might need a small sample of the fluid coming from your eye. This is called a culture test. A culture test is more likely if:

• Your symptoms are very bad. This could mean a lot of pain, redness, or discharge.
• Your doctor thinks there might be a serious problem. This could be something like:
  • A foreign object in your eye. This could be something like a small piece of dust or a bit of sand.
  • A really bad bacterial infection. This is a more serious infection than a typical pink eye case.
  • A sexually transmitted infection (STI). Pink eye can sometimes be a sign of an STI.

In short, a simple check-up is usually enough to know if you have pink eye. However, if the symptoms are severe or there's a suspicion of a more serious problem, a culture test might be needed.

Pink eye, or conjunctivitis, treatment mainly focuses on easing the symptoms. Your doctor might suggest:

• Artificial tears: These can help lubricate and soothe your eyes.
• Cleaning: Gently cleaning your eyelids with a damp cloth can remove irritants and help with comfort.

Contact Lenses: If you wear contacts, you should stop wearing them until the pink eye clears up. Your doctor will likely advise you to throw away any soft contact lenses you've used since the infection started. Hard lenses should be thoroughly disinfected overnight before reuse. You should also ask your doctor if you need to replace any contact lens accessories, like the case, and any eye makeup you used before the infection.

Antibiotics: In most cases, you don't need antibiotic eye drops. Pink eye is often caused by a virus, and antibiotics won't work against viruses. In fact, using antibiotics when not needed can reduce their effectiveness in the future or cause side effects. The virus needs time to run its course, which usually takes about 2 to 3 weeks.

Spread: Pink eye often starts in one eye and spreads to the other within a few days. Your symptoms should get better on their own over time.

Other Treatments: Antiviral medications might be an option if your pink eye is caused by the herpes simplex virus.

Allergies: If your pink eye is caused by an allergy, your doctor might prescribe eye drops. These drops can help control the allergic reaction, such as antihistamines or mast cell stabilizers, or reduce inflammation, such as decongestants, steroids, or anti-inflammatory drops. Over-the-counter versions of these medicines may also be helpful. Ask your doctor for the best option for you.

Prevention: You can often lessen allergic pink eye symptoms by avoiding the things that trigger your allergies.

Pink eye, also called conjunctivitis, can be uncomfortable. Here are some things you can do to ease your symptoms until they clear up:

Eye Drops: Using artificial tears, which are over-the-counter eye drops, can help soothe and lubricate your eyes. These drops can help relieve dryness, a common symptom of pink eye. Some eye drops also contain antihistamines or other medications. These are especially helpful if your pink eye is caused by an allergy.

Contact Lenses: If you wear contact lenses, you should probably stop wearing them until your pink eye is better. The length of time you need to stop wearing them depends on the cause of your conjunctivitis. It's a good idea to talk to your doctor or other healthcare provider about whether you should throw away your disposable contacts, cleaning solution, and lens case. If your lenses aren't disposable, make sure to thoroughly clean them before putting them back in. This helps prevent the spread of infection.
