Houston’s long allergy season, plus indoor AC, can itch or irritate any eye. But why does this concerning condition often go unnoticed? Dr. Jennifer Vuong, therapeutic optometrist for The Dry Eye Studio in Houston, breaks down allergies vs dry eye so you can choose smart, safe relief for each condition and when it’s time to get a real eye exam.
Quick reality check: how common are they?
Studies show that nearly 40% of Americans struggle with allergic conjunctivitis along with symptoms of ocular allergy. This list of allergens includes pollen, mold, cat and dog dander, and dust mites. So, it’s easy to comprehend how common allergy season is in Houston.
On the other hand, dry eye disease makes life hard for nearly 16.4 million US adults (6.8%), and the risk of developing it increases as people age.
Why should this matter to you
While symptoms of dry eye and eye allergy often appear similar, the care plan is different. Fixing the underlying cause keeps the ocular surface healthy and saves you the guesswork of trial-and-error treatment.

Spot-the-difference: symptoms and timing
Itch vs burn
Intense itch is the tell-tale sign of eye allergies; histamine reddens, puffs up, and dampens the conjunctiva. Dryness, grittiness, and fluctuating vision are signs of dry eye, where an unstable tear film irritates the surface.
Season and triggers
Allergy flares follow pollen season, dust, or breezy weather. Dry eye flares happen when you spend too much time in front of a digital screen. You can also struggle with dry eye disease if you stay close to air-conditioning, dry weather, or wind, and it can be chronic and year-round.
What your eye exam may include
Expect surface staining, tear breakup time, meibomian gland assessment, and (when needed) Schirmer testing to quantify tears. These tests separate allergic inflammation from evaporative or aqueous-deficient dry eye disease.
What is effective and safe
When allergies are the cause
Start with cold compresses and eye drops. Combine antihistamine with mast-cell stabilizer drops (such as ketotifen or olopatadine class) to reduce itch and redness. Reduce exposure to allergens: close windows on high-pollen days, use high-quality air conditioning filters, and clean your eyelashes after stepping inside the home.
If you’ve dry eye
Use lipid-supporting artificial tears, warm compresses, and eyelid hygiene for meibomian gland dysfunction. For persistent symptoms, your doctor may add anti-inflammatory prescriptions (like cyclosporine or lifitegrast) and in-office treatment options targeting the glands (e.g., thermal expression, light-based therapies).
Not sure which bucket you’re in? A quick consult with an eye doctor in Houston prevents months of the wrong drops and ongoing irritation.
When to make an appointment today
Sudden severe onset of light sensitivity, reduced vision, constant styes, or no response after a week of OTC therapy necessitates a full checkup. Since these problems are so prevalent, early diagnosis ensures comfort and quick healing from the annoying eye condition.
