How Do I Know If I Have an Eye Infection or Allergies?

When your eyes suddenly become red, irritated, or watery, it can be hard to tell whether you're dealing with allergies or an actual eye infection. While the symptoms may overlap, the causes and treatments are very different. Knowing the difference can help you get the right care quickly.

Common Symptoms of Eye Allergies

Eye allergies occur when your immune system reacts to allergens like pollen, dust, pet dander, or mold. They’re uncomfortable, but typically not harmful to your vision.

Typical signs of eye allergies include:

• Itchy eyes (one of the most telling symptoms)

• Red or watery eyes

• Swelling around the eyes

• Burning or mild irritation

• Stringy, clear discharge

• Symptoms that worsen during allergy season or in certain environments

Allergic reactions usually affect both eyes and tend to improve with antihistamines or avoiding triggers.

Common Symptoms of an Eye Infection

Eye infections are caused by bacteria, viruses, or fungi. They can affect the eyelids, cornea, or the membrane lining the eye. These conditions usually require treatment to prevent complications.

Signs you may have an infection include:

• Thick, yellow or green discharge

• Eyelids stuck together in the morning

• Significant redness or pain

• Light sensitivity

• Blurry vision

• A “gritty” sensation in the eye

• Symptoms that may start in one eye and spread to the other

Unlike allergies, infections often worsen quickly without proper care.

When to See an Eye Doctor

Because infections and allergies can look similar, it’s important not to guess - especially if symptoms persist or worsen. Eye infections can lead to corneal damage if untreated, while uncontrolled allergies can cause chronic irritation. We offer medical eye exams in Brookville to diagnose the exact cause of your symptoms and recommend the right treatment, whether you need allergy management, prescription drops, or infection care.
