Your Eyes During Allergy Season [Katy Edition]
By: Dr. Matthew Pham Updated: April 8th 2026
Every spring, Katy turns into a pollen storm. Cars get coated in yellow dust. People start sneezing. And a lot of patients walk into our office with eyes that are red, itchy, watery, and miserable. While this article is geared towards our patients, this would apply to most other locations too.
What Allergy Eyes Actually Feel Like
Ocular allergies, officially called allergic conjunctivitis, happen when your immune system overreacts to airborne allergens. The allergen lands on the surface of the eye, and your body releases histamine. That's what causes all the misery.
The most common symptoms:
-
Intense itching (the hallmark symptom, dry eye rarely itches like this)
-
Watery, clear discharge
-
Redness across the white of the eye
-
Eyelid swelling, sometimes significant by morning
-
Burning or stinging sensation
The itch is the key detail. If your eyes itch intensely and it gets worse when you're outdoors or in high-pollen environments, allergies are almost certainly the culprit.
One important distinction: allergic conjunctivitis doesn't cause pain or vision loss. If you're experiencing either of those, that's a different situation and you should call us promptly.
Why Katy is Especially Brutal for Allergy Sufferers
This isn't just regular allergy season. The Houston-Katy corridor has its own year-round gauntlet.
December - February: Cedar Fever
Mountain cedar (Ashe juniper) explodes in the winter months. People in Katy call it "cedar fever" because the symptoms can mimic the flu. High fever, fatigue, nasal congestion, and very unhappy eyes. If your allergies peak in January, cedar is almost certainly why.
March - May: Oak and Tree Pollen Season
Once cedar winds down, oak takes over. This is the yellow dust on your car season. Oak pollen is extremely fine and disperses wide, meaning it gets in your eyes even on days that don't feel particularly windy. Pecan, elm, and pine also contribute significantly during these months. Katy is unique because you have areas where there’s a lot of established oak trees but in the new developments all the developers are choosing oaks for their preferred tree in people’s front yards as well.
Late Spring - Summer: Grass Pollen
Bermuda and other grasses peak from May through early summer. The warm Katy climate means grass stays active longer than it would in states with harder winters. If your eyes are still miserable in June, grass is likely why.
Year-Round: Mold and Humidity
Katy's heat and humidity create ideal conditions for mold spores. After rain events, mold counts spike fast. Mold is an underappreciated trigger for ocular allergies and can cause symptoms even when pollen counts are low.
Bottom line: between cedar, oak, grass, and mold, most Katy patients have something to react to in every single month of the year.
What We Look for in the Clinic
Symptoms tell part of the story. What we find during the exam tells the rest.
One of the most important signs we look for is papillae on the inner eyelids. To examine these, we evert (flip) the upper eyelid and look at the conjunctival tissue on the underside.
Papillae are small, raised bumps that form when inflammatory cells cluster in the conjunctival tissue. They look like a cobblestone pattern under the lid. Their presence tells us that chronic inflammation has been building up, often from repeated allergen exposure or extended contact lens wear during allergy season.
The size matters too. Small papillae are typical in seasonal allergies. Larger papillae, a condition called giant papillary conjunctivitis (GPC), are a bigger problem, usually triggered by contact lens wear during high-pollen periods. GPC can make contacts unwearable until the inflammation resolves.
This is one of Dr. Pham's patient's lower eyelid showing an allergic response. The green tears provide contrast so we can see the elevated red bumps in isolation. We also see there are areas of green that appear bumpy too. This irregular surface will cause irritation and itch and needs to be treated to smooth out the eyelid tissue.
We also look for:
-
Chemosis: swelling of the conjunctiva (the clear membrane over the white of the eye), which can look like a blister on the eye surface
-
Conjunctival redness, similiar but not quite the redness you'd see with infection
-
Eyelid swelling, especially when it's worse in the morning after a high-pollen night
-
Tear film quality, since allergies disrupt the normal tear layer and can layer dry eye symptoms on top of allergic ones
This is why it's useful to be seen during allergy season rather than just guessing. Dry eye, allergic conjunctivitis, and infections can look very similar. They even all might be happening at once!
What Actually Helps
The good news: ocular allergies are very treatable. The bad news: not everything marketed for "red eyes" is the right tool.
Antihistamine Eye Drops
These are the frontline treatment. Over-the-counter options like ketotifen (Zaditor, Alaway) and olopatadine (Pataday) are both antihistamine and mast-cell stabilizers. They block histamine at the receptor and prevent future histamine release. Twice-daily dosing works well for most patients but olopatadine has a once a day dosing that’s even easier.
Avoid drops labeled "gets the red out" (like Visine). Those use vasoconstrictors that reduce redness by shrinking blood vessels. They don't treat the allergy, and with regular use, they cause rebound redness when you stop. They can also mask symptoms that might need a closer look.
Prescription Eye Drops
For moderate to severe cases, we often will start a short round of topical steroids to quickly dampen the immune system response. Steroid eye drops are very effective, but they require monitoring and aren't something to use long-term without follow-up. We often have patients with GPC or persistent inflammation that they tolerate until spring time and then we have to do a lot to reset everything.
Cool Compresses
Simple and underrated advice. Place a clean, cool compress (a damp washcloth straight from the fridge works fine) to the closed eyes for 5-10 minutes and that’ll reduce histamine activity in the tissue and decreases swelling. Cold constricts blood vessels and dulls the itch signal.
Do this twice daily during peak symptoms. It pairs well with drops and doesn't add any medication.
Oral Antihistamines
Second-generation antihistamines like cetirizine (Zyrtec), loratadine (Claritin), or fexofenadine (Allegra) help with systemic allergy symptoms and can reduce ocular symptoms as well.
One catch: oral antihistamines can be drying. For patients who already have dry eye, they can make ocular surface problems worse. If your eyes feel gritty or uncomfortable after starting an oral antihistamine, that's probably why. Preservative-free artificial tears will then be need to be used to offset that dryness portion.
Lubricating Eye Drops (Artificial Tears)
Preservative-free artificial tears do 2 useful things during allergy season: they dilute and rinse allergens off the ocular surface, and they restore the tear film that allergen-driven inflammation tends to disrupt. Using them before antihistamine drops can help those drops work more effectively. But space out when you would apply the drops.
Contact Lens Considerations
Contact lenses can hold allergens on the eye surface and worsen symptoms. During peak allergy weeks, switching to glasses even occasionally can make a significant difference. If you wear contacts during allergy season, daily disposable lenses are the better option since you're not reintroducing a pollen-loaded lens each day.
FAQ's
What are eye allergies symptoms?
Itchy eyes, redness, and eyelid swelling.
What are ways to relief eye allergies?
Allergy medicine such as antihistamine eye drops or oral gen 2 antihistamines
How to relieve eye itching?
Eye drops such as alaway and cool compresses work well.
Why do my eyes itch?
Your eye and the eyelid tissue reacts to allergens such as pollen which causes a histamine reaction that makes your eyes itch.
What is the best eye allergy treatment at home?
Artificial tears to rinse any pollen and using over the counter eye drops such as alaway
How long do eye allergies last?
They can be chronic and flare up when pollen counts are higher. The eye can be treated to reduce the papillae which would bring a longer period of relief before potential flare ups occur.
When to Come See Us
OTC drops handle mild seasonal symptoms well. Come in if:
-
Symptoms aren't responding to OTC drops after 1-2 weeks
-
You have significant eyelid swelling or discharge that's thick or colored
-
You're a contact lens wearer with worsening discomfort or decreased wearing time
-
Your vision is affected, even slightly
-
You've been using "get the red out" drops daily and can't stop without the redness coming back
Allergy season is predictable. It comes back every year. Getting a proper baseline exam and a clear treatment plan makes the next season easier to handle. We will formulate a plan for you so that you don't have to keep treating these conditions all year!
