If your eyes become itchy, red, watery, or swollen during certain times of the year - or in specific environments - you may be dealing with eye allergies. Also known as allergic conjunctivitis, eye allergies are a common condition that can significantly impact your comfort and quality of life. At Palo Alto Eyes Optometry, we help patients identify the root cause of their symptoms and find lasting relief.

What Are Eye Allergies?

Eye allergies occur when your immune system overreacts to a typically harmless substance, known as an allergen. When your eyes are exposed to an allergen, your body releases histamines and other chemicals that cause inflammation in the conjunctiva - the thin membrane covering the white of your eye.

Common Triggers of Eye Allergies

Understanding what’s causing your symptoms is the first step toward relief. Common triggers include:

• Pollen: Seasonal allergies are often caused by tree, grass, or weed pollen. In areas like Palo Alto, pollen levels can rise during spring and fall, leading to increased eye irritation.
• Dust Mites: These microscopic organisms thrive in bedding, upholstery, and carpets. They can trigger year-round (perennial) eye allergies.
• Pet Dander: Proteins found in an animal’s skin flakes, saliva, and urine can cause allergic reactions - even if the pet isn’t in the room.
• Mold: Mold spores, both indoors and outdoors, can irritate sensitive eyes, especially in damp environments.
• Smoke and Air Pollution: While not true allergens, irritants like cigarette smoke, wildfire smoke, and pollution can worsen allergy symptoms and inflame the eyes.

Signs and Symptoms

Eye allergy symptoms can range from mild to severe and may affect one or both eyes. Common symptoms include:

• Itchy eyes
• Redness
• Watery discharge
• Burning sensation
• Swollen eyelids
• Sensitivity to light
• Stringy mucus

If you wear contact lenses, you may notice increased discomfort or lens intolerance during allergy flare-ups.

How to Find Relief

There are several effective ways to manage eye allergies and reduce discomfort. Start by minimizing exposure to allergens - keep windows closed during high pollen seasons, use air purifiers indoors, wash your hands often, and avoid rubbing your eyes.

For quick relief, apply a cold compress to soothe itching and inflammation. Preservative-free artificial tears can also help flush allergens from the eyes and keep them lubricated. Over-the-counter antihistamine or mast cell stabilizer drops may reduce redness and itching, while prescription options are available for more persistent symptoms.

If you wear contact lenses, consider switching to daily disposables or wearing glasses during allergy season to reduce irritation.

When to See an Eye Doctor

While many cases of eye allergies are mild, persistent or severe symptoms should be evaluated by an eye care professional. Symptoms such as intense pain, significant vision changes, or thick discharge may indicate another condition requiring treatment.

At Palo Alto Eyes Optometry, we perform comprehensive eye exams to determine whether your symptoms are allergy-related or caused by another issue. We can recommend personalized treatment options to help you stay comfortable year-round.
