Eye allergy treatment in San Antonio
Relief for itchy, red, watery eyes, and a plan for every season
Eye allergies, also called allergic conjunctivitis, happen when your eyes react to allergens such as pollen, dust, mold, or pet dander. The result is itching, redness, and watery discharge, and in San Antonio, allergens cycle year-round, so many people never get a break. Treatment usually means avoiding your triggers, using antihistamine or lubricating “barrier” eye drops, and keeping your eyes and eyelids clean, and a few simple habits can prevent further irritation. At San Antonio Eye & Face Institute, our ophthalmologists make sure it’s actually allergy (not an infection or dry eye), recommend the right drops for you, and watch for problems, including eye pressure if steroid drops are ever needed.

What are eye allergies?
Allergic conjunctivitis occurs when the conjunctiva (the clear membrane covering the white of the eye and lining the eyelids) reacts to an allergen. Cells in the tissue release histamine and other chemicals, which cause itching, swelling, redness, and tearing. Eye allergies are common, and they often occur along with sneezing, a runny nose, and other allergy symptoms, though some people have eye symptoms alone. It’s not contagious.
Symptoms of eye allergies
- Itching, the hallmark symptom
- Redness of the eyes
- Watery or stringy discharge
- Burning or stinging
- Puffy or swollen eyelids
- Light sensitivity (usually mild)
- A runny nose, sneezing, or itchy nose or throat
Symptoms typically affect both eyes and come and go with exposure or the season.
Allergies, pink eye, or dry eye?
| Allergies | Infectious pink eye | Dry eye | |
|---|---|---|---|
| Main symptom | Itching | Redness, discharge, gritty feeling | Burning, grittiness |
| Discharge | Watery or stringy | Thick yellow or green, crusting | Little, or watery |
| Which eyes | Usually both | Often starts in one, then spreads | Usually both |
| Contagious? | No | Often yes | No |
| Other clues | Sneezing, runny nose, seasonal pattern | Recent cold or exposure | Worse with screens, wind, fans |
Because they can look alike, and because the treatments are different, an exam is the best way to tell. Allergies and dry eye also overlap, which is why we check both.

Eye allergy triggers in San Antonio
Allergens in San Antonio change with the seasons, and some are present all year.
| Trigger | When it’s typically worst |
|---|---|
| Mountain cedar (“cedar fever”) | Winter (roughly December to February) |
| Oak and other tree pollens | Late winter and spring (roughly February to April) |
| Grass pollen (such as Bermuda) | Spring through fall |
| Ragweed and other weeds | Late summer and fall |
| Mold spores | Year-round, often worse after rain |
| Dust mites and pet dander | Year-round, especially indoors |
| Dust and smoke | Windy, dry days, and occasional Saharan dust in summer |
Since San Antonio has multiple allergy seasons, many people have symptoms in more than one, or all year. If your eyes are itchy at different times of year, a pattern may point to your triggers.
Types of eye allergies
- Seasonal allergic conjunctivitis: the most common type, triggered by outdoor pollens during certain seasons
- Perennial allergic conjunctivitis: year-round symptoms from indoor allergens such as dust mites, mold, and pet dander
- Contact allergy: a reaction to cosmetics, eye drops, preservatives, or lens solutions
- Giant papillary conjunctivitis: an allergic reaction linked to contact lenses
- Vernal and atopic keratoconjunctivitis: severe forms that can affect the cornea, usually in children and teens (vernal) or people with eczema or asthma (atopic), and that need specialist care
What to do at home
- Avoid your triggers when you can. Check pollen counts, and limit time outdoors on high-pollen days.
- Keep windows closed and use air conditioning, ideally with a good filter, in your home and car on high-pollen days.
- Wash up after being outdoors. Rinse your face and hands, change clothes, and shower before bed to wash pollen off your hair.
- Don’t rub your eyes. Rubbing makes itching worse and can damage the surface of the eye.
- Use cold compresses over closed eyes to calm itching and swelling.
- Use preservative-free artificial tears to rinse allergens from the surface of the eye, as often as you need.
- Control indoor allergens. Wash bedding weekly in hot water, use dust mite covers, keep humidity down to limit mold, and keep pets out of the bedroom.
- Wear sunglasses outdoors to keep pollen and wind off your eyes.
- Take care with contact lenses. Allergens stick to lenses, so consider daily disposables, follow good hygiene, and wear glasses during flares.
- Remove eye makeup every night, and keep your eyelids clean.

Eye drops for allergies
- Lubricating “barrier” drops coat the eye and help wash away and block allergens. Preservative-free artificial tears can be used as often as needed. They relieve symptoms but don’t stop the allergic reaction by themselves.
- Antihistamine and mast cell stabilizer drops (such as olopatadine, ketotifen, alcaftadine, azelastine, epinastine, bepotastine, and cetirizine) relieve itching and redness and may also help prevent symptoms when used regularly. Many are available over the counter, and others by prescription. Some take a few days for full effect.
- Redness-relief drops (the “gets the red out” kind) aren’t a good long-term choice. They can cause rebound redness and don’t treat the allergy.
- Steroid drops are usually not needed. We use them only for a short time in severe flares, since they can raise eye pressure, increase cataract risk, and can worsen certain types of infections. We monitor your eye pressure carefully if you need them. Glaucoma
- Prescription anti-inflammatory ointments or drops (such as cyclosporine or tacrolimus) may be used for severe forms such as vernal or atopic keratoconjunctivitis, often with specialist care.
Use any drops as directed, and ask us before using them with contact lenses. If you use several drops, wait about 5 minutes between them. Preservatives in some drops can irritate the eyes, and preservative-free options are available.
Allergy pills, shots, and your allergist
Oral antihistamines can relieve eye symptoms, but they can reduce tear production, especially older ones, and worsen dry eye. Tell us about the allergy medicines you take. An allergist can identify your triggers with testing and discuss options such as allergy shots or drops (immunotherapy), which treat the cause of the allergy. We coordinate with your allergist and primary care doctor.
How we diagnose eye allergies
We ask about your symptoms and when they occur, your allergies and medicines, and your contact lens use. Then we examine your eyes with a slit lamp to look at the surface of the eye, your eyelids, and the inside of the eyelids, which helps tell allergy from infection, dry eye, or eyelid disease. We may also check your eye pressure. Most people don’t need special tests.
When to see an eye doctor
See us if your symptoms don’t improve with drops and avoiding triggers, or if you have frequent or year-round symptoms. Get care right away for eye pain, a sudden change in vision, strong light sensitivity, thick discharge, or redness with contact lens wear.
Cost and insurance
An eye exam for allergies is generally covered by medical insurance, while over-the-counter drops are paid for out of pocket and prescription drops are covered according to your drug plan. Call us and we’ll check your benefits.

Frequently asked questions
What are eye allergies? Eye allergies, also called allergic conjunctivitis, happen when the eyes react to allergens such as pollen, dust, mold, or pet dander. The reaction causes itching, redness, watery discharge, and sometimes swollen eyelids, usually in both eyes.
What are the symptoms of eye allergies? The hallmark symptom is itching, along with redness, watery or stringy discharge, burning, puffy or swollen eyelids, and sometimes a runny nose or sneezing. Symptoms usually affect both eyes and often come and go with the season or exposure.
What triggers eye allergies in San Antonio? Common triggers include mountain cedar pollen (cedar fever, usually in winter), oak and other tree pollens in spring, grass and ragweed pollen, mold, dust and dust mites, and pet dander. Allergens cycle year-round in San Antonio, so many people have symptoms in more than one season.
Are eye allergies contagious? No. Allergic conjunctivitis is not contagious. Infectious causes of red eyes, such as viral or bacterial pink eye, can spread, which is one reason an accurate diagnosis matters.
How can I tell eye allergies from pink eye? Allergies usually cause intense itching and watery or stringy discharge in both eyes at once, while infectious pink eye is more likely to cause thick yellow or green discharge, crusting, or a gritty feeling and can be contagious. Only an exam can tell for sure.
What eye drops help with eye allergies? Antihistamine and mast cell stabilizer drops relieve itching and redness, and many are available over the counter or by prescription. They work best when used regularly during allergy season, and some take a few days to reach full effect.
What are barrier or lubricating eye drops? Lubricating, or barrier, drops coat the surface of the eye and help flush out and block allergens, and preservative-free artificial tears can be used as often as needed for comfort. They relieve symptoms but do not stop the allergic reaction by themselves.
Should I use redness-relief drops like Visine for allergies? Not regularly. Drops that whiten the eyes can cause rebound redness when used often and do not treat the allergy. Ask us about better options.
Is it okay to rub itchy eyes? No. Rubbing releases more of the chemicals that cause itching and can irritate and damage the eye surface, and long-term eye rubbing is linked to keratoconus, a condition that thins the cornea. Use cold compresses and drops instead.
Do I need steroid eye drops for allergies? Usually not. Steroid drops are sometimes used for a short time for severe flares, but they can raise eye pressure, increase the risk of cataracts, and make infections worse, so they should only be used under an eye doctor’s supervision with follow-up pressure checks.
Can allergy pills make my eyes dry? Yes. Oral antihistamines, especially older ones, can reduce tear production and worsen dry eye, so tell us about the allergy medicines you take.
Can I wear contact lenses with eye allergies? Allergens stick to contact lenses and can make symptoms worse. Daily disposable lenses, good lens hygiene, and taking a break from lenses during flares can help, and ask us before using any drops while wearing lenses.
How can I reduce eye allergy symptoms at home? Avoid known triggers, keep windows closed on high-pollen days, wash your face and hands after being outdoors, use cold compresses, wash bedding in hot water weekly, keep pets out of the bedroom, and wear sunglasses outside. Do not rub your eyes.
Are eye allergies related to dry eye? They often overlap. Dry eye can make allergy symptoms feel worse, and some allergy treatments can dry the eyes, so we check for both.
Can eye allergies damage my vision? Common seasonal and year-round allergies rarely damage vision. Severe forms, such as vernal and atopic keratoconjunctivitis, can affect the cornea and need specialist care, and eye rubbing and long-term steroid use can cause problems.
Do children get eye allergies? Yes. Eye allergies are common in children. Most are mild, but a severe form called vernal keratoconjunctivitis mainly affects children and teens and needs prompt care.
Should I see an allergist too? Often, yes. An allergist can identify your triggers with testing and discuss allergy shots or drops, and we coordinate with them to treat your eyes.
When should I see an eye doctor for allergies? See an eye doctor if your symptoms do not improve with drops and avoiding triggers, and right away if you have eye pain, vision changes, strong light sensitivity, thick discharge, or redness while wearing contact lenses.
Is eye allergy treatment covered by insurance? An eye exam for allergies is generally covered by medical insurance, while over-the-counter drops are paid out of pocket and prescription drops are covered according to your drug plan.
Who treats eye allergies at your practice? Both of our ophthalmologists evaluate and treat eye allergies. We monitor eye pressure carefully if steroid drops are ever needed.
