Do Allergies Affect Your Eyes?

If your eyes feel itchy, red, watery, or irritated during certain times of the year, allergies may be the culprit. Eye allergies are extremely common and can significantly impact your comfort and vision. Understanding how allergies affect your eyes and what you can do about them is the first step toward lasting relief.

How Allergies Impact Your Eyes

Eye allergies occur when your immune system overreacts to substances in the environment that are usually harmless. Common allergens include pollen, dust mites, mold, and pet dander. When your eyes are exposed to these allergens, they release histamines, which trigger inflammation and irritation.

Common Eye Allergy Symptoms

Eye allergies can affect people of all ages and often accompany seasonal or environmental allergies. Symptoms may include:

• Itchy or burning eyes

• Redness or bloodshot appearance

• Excessive tearing or watery eyes

• Swollen eyelids

• Sensitivity to light

• Stringy or watery discharge

Many people also experience allergy-related dry eye symptoms, which can make irritation feel even worse.

Seasonal vs. Year-Round Eye Allergies and Their Link to Dry Eye

Not all eye allergies are the same, and they generally fall into two main categories. Understanding which type you’re experiencing can make a significant difference in how your symptoms are managed - especially since allergies often overlap with dry eye syndrome, making discomfort feel more severe.

Seasonal eye allergies are most commonly caused by pollen from trees, grasses, and weeds. Symptoms tend to flare up during specific times of the year - most often in the spring, summer, or fall - depending on when certain plants release pollen into the air. During allergy season, inflammation from allergens can disrupt the tear film, worsening dryness, irritation, and burning sensations.

Perennial, or year-round, eye allergies are triggered by indoor allergens such as dust mites, mold, or pet dander. Because these allergens are present throughout the year, symptoms may be ongoing. Chronic exposure can contribute to dry eye syndrome by reducing tear quality and increasing eye surface inflammation, leading to persistent redness, grittiness, and blurred vision.

Treatment Options for Eye Allergies

Relief starts with identifying triggers and minimizing exposure, but treatment often requires more than just avoidance. Common options include:

• Prescription or over-the-counter allergy eye drops

• Anti-inflammatory medications

• Artificial tears to flush out allergens

• Lifestyle and environmental adjustments

Your eye doctor can recommend treatments tailored to your specific symptoms and lifestyle.
