Pink eye is one of the most common reasons travelers walk into our Patong clinic, particularly after a few days of pool and beach use or a recent flight. Most cases look alike at first glance, but the cause matters: viral pink eye needs comfort care only, bacterial pink eye needs antibiotic drops, and allergic pink eye needs antihistamine drops. Getting the diagnosis right on day one usually means feeling much better within 48 hours.
Types and causes of pink eye
Viral conjunctivitis is by far the most common form, accounting for roughly 80 percent of cases we see. It is almost always caused by adenovirus, often follows a recent cold or sore throat, and typically starts in one eye and spreads to the other within a day or two. Discharge is watery rather than thick, and the eye feels gritty rather than glued shut. Bacterial conjunctivitis is less common in adults and is usually caused by Staphylococcus aureus, Streptococcus pneumoniae or Haemophilus influenzae. It produces sticky yellow or green discharge that mats the lashes together in the morning, often stays in one eye, and clears quickly on the right drop. Allergic conjunctivitis is the third pattern, affects both eyes from the start, and the dominant symptom is itch rather than discharge, often alongside a runny nose or sneezing.
Several Patong-specific triggers come up again and again in our consultations. Chlorinated pool water, salt water with sand contamination, air-conditioning that dries the tear film during a long flight, and intense ultraviolet reflection from white sand are common precipitants. Contact-lens wearers are a special group because the same red eye can mean a far more serious infection with Pseudomonas aeruginosa or, rarely, Acanthamoeba, both of which can damage the cornea permanently if missed. We tell every contact-lens wearer with a red eye to stop lens use immediately and come in the same day.
Treatment we prescribe for each type
For viral pink eye there is no antiviral drop that shortens the illness, and antibiotic drops are not helpful. The aim is comfort while the infection runs its 5 to 14 day course: artificial tears such as carboxymethylcellulose 0.5 percent four to six times a day, cool compresses for 5 to 10 minutes a few times a day, and strict hand hygiene to stop spread to the other eye and to family members. For bacterial pink eye we usually prescribe chloramphenicol 0.5 percent drops, one drop every 2 hours while awake for the first 2 to 3 days, then four times daily until symptoms have resolved for 48 hours, typically a 5 to 7 day course. Fusidic acid 1 percent gel twice daily is an alternative for patients who prefer fewer doses. For severe cases or suspected Pseudomonas in a contact-lens wearer we step up to a fluoroquinolone such as ciprofloxacin 0.3 percent drops alongside an urgent ophthalmology referral. For allergic conjunctivitis we prescribe a dual-action antihistamine and mast-cell stabiliser drop, usually olopatadine 0.1 percent twice daily, with oral cetirizine 10 mg once daily if there is an associated runny nose. Lubricant drops kept in the fridge make a big difference to itch within minutes.

How contagious is pink eye, and when to stay away
Viral and bacterial conjunctivitis are highly contagious, allergic conjunctivitis is not. Adenovirus survives on surfaces for days, which is why outbreaks sweep through hotels, dive boats and yoga studios. Spread is by direct hand to eye contact and by shared towels, pillows, makeup and eye drops. We ask patients to use a separate face cloth and pillowcase, wash hands before and after touching the eye, throw away any eye makeup used in the 48 hours before symptoms started, and avoid swimming pools until symptoms have fully resolved. School or work exclusion is 24 hours after the first dose of antibiotic for bacterial cases, or until watery discharge has stopped for viral cases, usually around 5 days.
When to see a doctor
Most pink eye is mild and resolves predictably, but a few presentations need urgent assessment because they can threaten sight. The classic red flags are severe pain, true light sensitivity, any change in vision, very heavy purulent discharge with marked swelling that has come on within 24 hours, and any red eye in a contact-lens wearer, a newborn or someone on chemotherapy or other immune-suppressing treatment.
Severe eye pain, true light sensitivity or any change in vision (possible herpes simplex keratitis, anterior uveitis or acute angle-closure glaucoma). Copious yellow-green discharge with marked lid swelling appearing within 12 to 24 hours (possible gonococcal conjunctivitis, sight-threatening, needs intramuscular ceftriaxone). A red painful eye in a contact-lens wearer (Pseudomonas or Acanthamoeba keratitis until proven otherwise, stop lens use now). Red eye in a newborn under 4 weeks old. Foreign-body sensation that does not settle, or any history of eye trauma, welding or strong UV exposure. Red eye in someone on chemotherapy, biologics or other immune-suppressing medication.
Symptoms have lasted more than 7 days without improvement, you cannot tell if your eye is sticky or itchy, you wear contact lenses, you are unsure whether what you have is pink eye at all, or you need a written diagnosis for travel insurance or a flight. A 10-minute exam, including fluorescein staining when needed, confirms the type and gets you on the right drop the same hour. WhatsApp +66 95 073 5550 for a same-day clinic or hotel-room visit.
Prevention and early self-care
Hand hygiene prevents more pink eye than any other measure. Wash hands before and after touching the face, do not rub the eyes, and keep a small bottle of alcohol gel for use after handling shared surfaces in hotels, gyms and boats. Contact-lens wearers should never sleep in lenses, never rinse lenses or cases with tap water, replace cases every 3 months, and remove lenses immediately at the first sign of redness. During an active outbreak, do not share towels, pillows, makeup or eye drops, and throw away any eye cosmetics used in the days before symptoms started, since the bottle is now contaminated. Swimmers prone to pool conjunctivitis benefit from well-fitted goggles. For allergic sufferers, the simplest preventive step is to identify and avoid the trigger, often dust mites in hotel pillows or pollen in the cool season, and to keep antihistamine drops in the fridge ready for the first itch.
Summary
Pink eye is common, usually mild, and almost always one of three patterns: viral, bacterial or allergic. Getting the type right on day one means viral cases get comfort care without unnecessary antibiotics, bacterial cases get the right drop and clear in days, and allergic cases get fast relief from itch. The cases that need urgent review are red eye in a contact-lens wearer, any change in vision or severe pain, very rapid heavy purulent discharge, and red eye in a newborn or immune-compromised patient.
“The mistake we see most often is a tourist starting antibiotic drops from a pharmacy for what is actually viral or allergic pink eye. A 10-minute exam tells us which of the three it is, and the right drop usually settles things within a day or two.”

Frequently asked questions
How long does pink eye take to clear?
Viral pink eye is self-limiting and takes 5 to 14 days to resolve fully, with the worst usually past by day 5. Bacterial pink eye starts to improve within 24 to 48 hours of starting the right antibiotic drop and is usually clear in 5 to 7 days. Allergic pink eye often settles within hours of the first antihistamine drop but returns if the trigger is not avoided.
Do I need antibiotic drops for pink eye?
Only if it is bacterial. Most adult pink eye is viral or allergic, where antibiotic drops do nothing and may cause stinging or allergy. A short exam, looking at the discharge type, eye distribution and history of recent cold or itch, tells us which type you have. We prescribe an antibiotic only when the pattern fits bacterial infection.
Is pink eye contagious, and when can I go back to work or the pool?
Viral and bacterial pink eye are highly contagious through hand contact and shared surfaces. Allergic pink eye is not. For bacterial cases we advise returning to work or school 24 hours after the first dose of antibiotic and the discharge has stopped. For viral cases, stay away from the pool and shared gym equipment until watery discharge has settled, usually around 5 days.
I wear contact lenses and my eye is red, what should I do?
Take the lenses out immediately and do not put them back in until a doctor has examined the eye. Contact-lens wearers can develop Pseudomonas or, rarely, Acanthamoeba keratitis, both of which can damage the cornea permanently. WhatsApp +66 95 073 5550 for a same-day review. Bring the lens case and solution with you.
Can the clinic come to my hotel for pink eye?
Yes. A doctor can visit your hotel anywhere in Patong, Kalim, Kamala, Karon and Surin to examine the eye, confirm the type and dispense drops on the spot, day or night. This is often easier than walking to the clinic with a sticky, light-sensitive eye.
When is pink eye an emergency?
Severe eye pain, light sensitivity or any change in vision, copious yellow-green discharge with marked lid swelling within 24 hours, red eye in a contact-lens wearer, red eye in a newborn, or any red eye in someone on immune-suppressing treatment should be seen the same day. These can mean herpes keratitis, gonococcal conjunctivitis or a corneal ulcer, all of which need urgent treatment to protect sight.
