A contact lens should not make your eye stay red, painful or unusually watery. Sometimes the cause is simple dryness, an allergy or a small piece of debris. Other times, redness and tearing can be early signs of a scratched cornea, inflammation or a contact lens-related infection.
The difficult part is that these problems can look similar at home. A watery eye does not automatically mean an infection, but contact lens wear lowers the threshold for getting checked—especially when pain, light sensitivity or blurry vision is present.
At See Well Eyecare in Hyde Park, Dr. Rawzi Baik evaluates contact lens concerns for patients from Cincinnati, Oakley, Mariemont and nearby communities. Here is what to do when a contact lens eye becomes red or watery, what not to do, and when the symptoms need prompt attention.
If an eye becomes red, painful, irritated or unusually watery while you are wearing a contact lens:
Wash your hands with soap and dry them completely.
Remove the contact lens if it comes out easily.
Do not put that lens—or a fresh lens—back into the irritated eye.
Switch to glasses until an eye doctor says it is safe to resume contact lens wear.
Contact an eye doctor promptly if symptoms are significant, worsening or not settling after lens removal.
Do not force out a lens that seems stuck. If removal causes significant pain or you cannot remove it safely, call an eye doctor for guidance.
If possible, keep the lens, case and solution you were using in a clean bag and bring them to your visit. Also bring the names or photos of any eye drops and contact lens products you recently used. That information may help identify a care problem, product reaction or infection risk.
Contact See Well Eyecare or another eye-care professional promptly—often the same day—if a contact lens wearer develops:
Eye pain or pain that continues after removing the lens
New sensitivity to light
Sudden or increasing blurry vision
Marked redness, especially in one eye
Unusual tearing or discharge
A white or gray spot on the clear front surface of the eye
A strong foreign-body feeling that does not go away
Swelling, difficulty opening the eye or rapidly worsening symptoms
Symptoms after sleeping, showering or swimming in contact lenses
Symptoms after an eye injury or chemical exposure
The Centers for Disease Control and Prevention lists red eyes, worsening pain, light sensitivity, sudden blurry vision, unusual watering and discharge among the warning symptoms of microbial keratitis, a serious corneal infection. The CDC advises contact lens wearers with these symptoms to remove their lenses and call an eye doctor immediately.
Do not wait for a routine annual appointment when pain, light sensitivity or a change in vision is present. Corneal problems can change quickly, and an in-person examination is the safest way to tell irritation from something more serious.
Seek emergency care without waiting for an office response if there is sudden severe vision loss, a serious eye injury, a chemical splash, an object embedded in the eye, severe pain with nausea, or vision changes with weakness, numbness, confusion, trouble speaking or another neurologic symptom.
For a chemical splash, begin rinsing the eye immediately with clean lukewarm water and continue while arranging emergency help. Do not delay rinsing to remove a contact lens first; it may wash out during irrigation.
If you have a choice of Cincinnati emergency departments, the University of Cincinnati Medical Center has access to ophthalmology services. Call 911 for a life-threatening emergency or when it is not safe to drive.
It sounds backward, but a dry or unstable tear film can trigger reflex tearing. The eye senses irritation and produces a burst of watery tears. Those tears may spill down the cheek without providing the balanced oil, water and mucus layers needed for lasting comfort.
Contact lenses interact with the tear film all day. Screen use, air conditioning, fans, seasonal allergies, certain medicines and meibomian gland dysfunction can make a lens feel dry or cause vision to fluctuate. A contact lens may also fit well in the morning but become uncomfortable later in the day.
If watering happens repeatedly, do not simply keep changing lubricating drops or contact lens brands on your own. A contact lens evaluation can assess the tear film, eyelids, cornea and lens fit so treatment is based on the cause.
Dryness may cause burning, fluctuating vision, a tired feeling or watery eyes. Symptoms often become more noticeable late in the day or during long periods of screen work.
Allergies often cause itching, watering and redness in both eyes. Rubbing can make the irritation worse. Some patients also develop inflammation under the upper eyelid that makes contacts feel less comfortable.
A lens that is too tight, too loose, damaged, inside out or worn beyond its replacement schedule can irritate the eye. Deposits can build on reusable lenses even when they still look clear.
Reusable lens solutions contain ingredients that may bother some eyes. Topping off old solution, using an expired product or changing products without guidance can also create problems.
A torn lens, fingernail, trapped particle or difficult lens removal can scratch the cornea. Abrasions may cause sharp pain, tearing, redness and light sensitivity.
Inflammation of the cornea can cause redness, discomfort and blurry vision. Microbial keratitis, sometimes called a corneal ulcer, can threaten sight if treatment is delayed. An eye doctor uses magnification, dyes and other tests to determine whether the cornea is involved.
Viral, bacterial and allergic conjunctivitis can all make eyes red and watery, but their treatment and contagiousness differ. A contact lens wearer with a red eye should not assume it is routine “pink eye” or use someone else’s drops.
Do not put the contact lens back in to “see if it feels better.”
Do not sleep in the lens unless your eye doctor specifically prescribed overnight wear—and never sleep in it while the eye is red or irritated.
Do not rinse or store contacts in tap, bottled or distilled water.
Do not shower, swim or use a hot tub while wearing lenses.
Do not use saliva to wet a lens.
Do not top off yesterday’s solution with fresh solution.
Do not borrow another person’s drops or contact lenses.
Do not use leftover antibiotic or steroid eye drops. Steroids can worsen some infections and should be used only under professional supervision.
Do not rely on “get the red out” drops to hide the symptom.
Preservative-free lubricating drops may be appropriate for mild dryness, but they should not be used to postpone an examination when pain, light sensitivity, discharge or reduced vision is present.
The visit begins with questions about when the symptoms started, which eye is involved and whether you slept, showered or swam in your lenses. We may also ask about your lens brand, replacement schedule, cleaning routine, recent illness, allergies and any drops you used.
Dr. Baik may then check:
Vision in each eye
The eyelids and tear film
Contact lens fit, if it is safe and helpful to assess
The conjunctiva, cornea and front of the eye under a slit lamp
Corneal staining with a diagnostic dye
The inside of the eyelids when allergy or lens-related inflammation is suspected
Eye pressure or the back of the eye when symptoms make those tests relevant
Testing is tailored to the findings. The goal is to identify whether the problem is dryness, allergy, abrasion, inflammation, infection or another condition—and then create a safe plan for treatment and return to contact lens wear.
That answer depends on the diagnosis. Some mild irritation settles after a short break and a change in lens care. An abrasion, significant inflammation or infection may require treatment and follow-up before contacts are safe again.
Do not restart on your own simply because the eye looks whiter. Pain and redness can improve before the cornea has fully recovered. When contact lens wear resumes, your doctor may recommend a fresh lens, new case, different solution, revised wearing schedule or a different lens design.
A glasses prescription measures the lens power needed in front of the eye. A contact lens rests directly on the tear film and cornea, so its material, shape, movement, oxygen performance and replacement schedule also matter.
If your contacts often become dry, red or uncomfortable, a dedicated contact lens evaluation may be more useful than repeatedly buying the same lens. Dr. Baik can review daily disposable, reusable, toric, multifocal and specialty contact lens options based on your eyes and routine.
Established patients with an after-hours or weekend eye concern may call or text our office at (513) 268-8748. We will call or text back to connect. If you have not heard from us within four hours, go to the closest emergency department. If you have a choice, University of Cincinnati Medical Center is often preferable for an eye emergency because ophthalmology services are available.
Do not wait four hours when symptoms are severe, rapidly worsening or potentially sight-threatening. Go directly to emergency care for the warning signs described above.
If you are new to See Well Eyecare and want to establish care, contact us and our team will respond when the office opens to gather information and schedule an evaluation. New patients with urgent or severe symptoms should not wait for the office to open; seek appropriate urgent or emergency care.

Wash and completely dry your hands before touching lenses.
Follow the wearing and replacement schedule prescribed for your lens.
Use fresh recommended solution every time; never top off old solution.
Clean and replace the case as directed.
Keep lenses away from water.
Do not sleep in lenses unless specifically prescribed.
Keep a current pair of glasses with you.
Stop lens wear and contact an eye doctor when symptoms begin.
Keep regular eye and contact lens examinations even when the lenses feel fine.
Good habits lower risk, but even careful contact lens wearers can develop irritation or infection. Early action matters more than blame.
See Well Eyecare is located in Hyde Park (45208), close to the shops and everyday routines around Hyde Park Square. We are also convenient for professionals and families in Oakley (45209) and Mariemont (45227) who need personalized contact lens care or an evaluation for a red, watery or uncomfortable eye.
Keep a backup pair of glasses in your work bag, school bag or car so you never feel pressured to keep wearing an uncomfortable lens while traveling around Cincinnati.
Cincinnati has several busy community weekends ahead. If you wear contacts for long outdoor days, pack your glasses, preservative-free lubricating drops recommended for you, and a clean way to remove your lenses if discomfort begins.
Hamilton County Days at the Cincinnati Zoo, August 21–23: The Cincinnati Zoo lists special Hamilton County admission days from 10 a.m. to 5 p.m. Heat, pollen and long outdoor hours can make contacts feel dry, so bring backup glasses.
Oktoberfest Zinzinnati, September 17–20: The official festival site lists four days at Sawyer Point and Yeatman’s Cove. Never rinse a dropped lens with bottled or tap water while away from home.
BLINK, October 8–11: The official BLINK site lists the light and art festival across Cincinnati and Northern Kentucky. If redness, pain or light sensitivity starts during a long evening downtown, remove the lens and do not push through the symptoms.
Event details may change. Check each organizer’s official website before leaving home.
Dryness, allergies, debris, a damaged lens, poor fit, inflammation, an abrasion or infection can all cause watering. Because these causes can feel similar, repeated or significant symptoms should be examined rather than guessed at home.
Yes. Wash and dry your hands, remove the lens if it comes out easily, switch to glasses and do not reinsert a lens until the eye is comfortable and, when symptoms are significant, an eye doctor has said it is safe.
No. Dryness and allergies can also cause redness and reflex tearing. However, pain, light sensitivity, sudden blur, discharge or worsening redness can signal a corneal problem and needs prompt attention.
Do not use a drop unless it is compatible with your lenses and appropriate for the cause. Drops that temporarily whiten the eye can mask a symptom. Remove the lenses and ask an eye-care professional which product is safe for you.
Remove the lenses, do not reinsert them and call an eye doctor promptly—especially if there is pain, light sensitivity, blurry vision, discharge or persistent redness.
No. Water is not sterile and can expose a lens to organisms that cause serious corneal infection. Use only the contact lens system recommended for you.
Not necessarily. If it can be done safely, place the lens, case and solution in a clean bag and bring them to the visit. Do not put the lens back in or continue handling it.
Mild irritation that resolves completely after lens removal may not be an emergency. Call promptly if the symptoms continue, recur or worsen. Pain, light sensitivity, reduced vision, discharge, a white spot or significant one-sided redness should not wait for a routine appointment.
