Eye infections are uncomfortable, disruptive, and sometimes contagious. One of the most common examples is conjunctivitis - better known as pink eye. While many infections can be mild, some can lead to more serious issues if not properly treated. Understanding how they spread, what symptoms to look for, and how to protect your eyes can help keep both you and your family safe.

What Causes Eye Infections?

Pink eye occurs when the thin, clear tissue that lines the inside of your eyelid and covers the white part of your eye (the conjunctiva) becomes inflamed. It can be triggered by:

• Viruses (often the same ones that cause the common cold)

• Bacteria (such as staphylococcus or streptococcus)

• Allergies (pollen, dust, pet dander)

• Irritants (smoke, chlorine, or contact lens misuse)

Viral and bacterial conjunctivitis are contagious, while allergic and irritant-related pink eye are not.

Recognizing the Symptoms

The symptoms of eye infections can vary, but some of the most common include:

• Redness or swelling of the eye and eyelid

• Watery or thick discharge from the eye

• Itchy or burning sensations

• Sensitivity to light

• A gritty feeling, as if something is stuck in your eye

If you notice these symptoms, especially if they come on suddenly or affect both eyes, it may be an infection.

How Eye Infections Spread

Contagious pink eye and other eye infections can spread quickly, especially in close-contact settings like schools or offices. They often spread through:

• Direct contact: Touching your eyes with unwashed hands

• Shared items: Towels, pillowcases, makeup, or contact lenses

• Respiratory droplets: Coughing or sneezing nearby can transfer viruses or bacteria

• Swimming pools: Without proper chlorine levels, bacteria can thrive in the water

How to Avoid Eye Infections

Protecting your eyes requires good hygiene and healthy habits:

• Wash your hands frequently and avoid rubbing your eyes

• Never share personal items like towels, washcloths, or cosmetics

• Properly clean and replace contact lenses as directed

• Disinfect surfaces such as doorknobs and light switches

• Wear protective eyewear when swimming or around irritants

• Avoid close contact with someone who has an eye infection

When to See Your Eye Doctor

Not all red or irritated eyes are dangerous, but it’s important to know when to seek care. If you experience persistent redness or swelling that doesn’t improve, severe pain or light sensitivity, thick yellow or green discharge, blurred or reduced vision, or symptoms that worsen after a few days, it’s time to schedule an appointment. An optometrist can diagnose the cause, recommend the right treatment, and help prevent potential complications.
