Conjunctivitis Treatment Online

Can an online doctor treat conjunctivitis?

Pink eye is a genuinely telehealth-suitable problem: the pattern of discharge, itch and spread tells the doctor most of what they need, and the priority is often reassurance plus hygiene rather than a prescription. Mobi Doctor, an online healthcare service with licensed doctors, can make that assessment, prescribe where it is truly warranted, and, just as importantly, recognise the red eyes that must be seen in person.

How an online consultation helps with conjunctivitis

? Photograph both eyes in daylight even if only one is affected, plus a close-up of the discharge and of the inner lower lid, pulled down gently. Take the pictures before wiping the eye clean. On the video call the doctor will also watch how you blink, how the eye moves and how you react to normal room light.

What the doctor checks in an online conjunctivitis consultation

The assessment is structured around type and safety. In a conjunctivitis consultation, the doctor will typically assess:

• Discharge type: watery points to viral or allergic causes; sticky yellow-green discharge that glues the lashes shut overnight points to bacterial infection.
• One eye or both: viral conjunctivitis often starts in one eye and spreads to the other within days; allergic conjunctivitis affects both together.
• Itch and allergy signals: intense itching with sneezing, an itchy nose or a pollen-season pattern points to allergy rather than infection.
• The red-flag screen, actively: true eye pain rather than grittiness, light sensitivity, blurred or reduced vision that blinking does not clear, halos around lights, unequal pupils, and any recent injury or chemical splash.^[1]
• Contact-lens use, always asked: a painful red eye in a lens wearer is treated as possible microbial keratitis until proven otherwise and goes to same-day in-person care.
• Context: a recent cold or sore throat, affected household members or colleagues, and whether there is a newborn baby in the house.
• On camera: how you tolerate normal room light, how clearly you can see across the room, and how the eye moves; your photos should show both eyes in daylight before wiping, plus a close-up of the discharge and the inner lower lid gently pulled down.

Viral, bacterial or allergic conjunctivitis?

The three main types of conjunctivitis are told apart by the discharge and the itch. Viral conjunctivitis is watery and often follows a cold; bacterial is sticky with yellow-green pus that glues the lashes; allergic conjunctivitis is intensely itchy, affects both eyes and comes with sneezing. Most conjunctivitis is viral and clears on its own.^[1]

Viral: the common one

Viral conjunctivitis produces a watery discharge and a burning, gritty feeling, typically starting in one eye and reaching the other within days, often alongside a cold or sore throat. It is highly contagious and simply runs its course over one to two weeks.^[1] Antibiotic drops do not work on viruses, which is why an honest assessment saves you a pointless prescription.

Bacterial: sticky and crusted

Bacterial conjunctivitis leans sticky: yellow-green discharge that glues the lashes together overnight.^[4] Even here, restraint pays. Many bacterial cases clear within about a week on their own, and drops are reserved for severe or persistent infections and for higher-risk people such as contact-lens wearers or the immunocompromised.^[3] Recurrent crusty, irritated lid margins without much discharge are more often blepharitis than conjunctivitis, and need a different approach.

Allergic: itchy, and in both eyes

When itching dominates and both eyes water together, usually with sneezing or an itchy nose in pollen season, or year-round with dust mites and pets, think allergic conjunctivitis. It is not contagious. Antihistamine or mast-cell stabiliser drops settle it, and treating the underlying allergy prevents the next round.^[2]

Stopping the spread, and the contact-lens rule

Hygiene that actually works

Wash your hands after any contact with your eyes; use your own towel, flannel and pillowcase and wash them hot; clean away discharge with cooled boiled water and a fresh cotton pad for each eye, wiping from the inner corner outwards.^[5] Bin eye make-up used while infected and pause make-up until the eye is clear. You are infectious while the eye is red and discharging; adults can generally keep working, while rules for childcare and schools vary from country to country, so check locally.

If you wear contact lenses

Stop wearing lenses at the first sign of redness and do not restart until the eye has been fully normal for a day or two after any treatment finishes. Discard the lenses you were wearing and the storage case: both harbour microbes. Never put drops in with a lens in unless the doctor confirms the drop is lens-compatible. And treat pain or light sensitivity in a lens wearer as an emergency needing same-day in-person care: microbial keratitis, the complication being ruled out, threatens sight.^[1]

Conjunctivitis in children, pregnancy and while travelling

Conjunctivitis is common in children and usually viral, so most cases need comfort measures and scrupulous hand-washing rather than drops; school and nursery exclusion rules differ across Europe, so check locally. A red or discharging eye in a newborn baby is different: it needs same-day in-person assessment, not online care, because the causes and risks in the first weeks of life are more serious.^[1]

In pregnancy most eye-drop treatments used for conjunctivitis are considered low risk, but tell the doctor you are pregnant or breastfeeding so the choice is made with that in mind. For travellers, pink eye is easy to pick up from pool water, shared towels and long flights in dry cabin air, and it spreads fast in shared accommodation. A photo and video consultation lets you have it assessed and, if drops are genuinely needed, have them sent to a pharmacy near you rather than searching for a clinic abroad. Contact-lens travellers should be especially strict with hygiene and carry glasses as a backup.

How long does conjunctivitis last?

Viral conjunctivitis usually lasts one to two weeks and can briefly worsen in the first few days before it improves. Bacterial conjunctivitis often settles within about a week, with or without drops.^[1] Allergic conjunctivitis persists as long as you are exposed to the allergen. See a doctor if symptoms last beyond two weeks or worsen.

A red eye dragging on well past two weeks is worth reassessing rather than waiting out, because a persistent red eye can point to something other than simple conjunctivitis: blepharitis, dry eye, or an allergy that needs different treatment. Any change in the picture, such as new pain, light sensitivity or blurred vision, is always a reason to be seen in person promptly.

How to use eye drops correctly

Getting drops in is half the battle. Wash your hands, tilt your head back, pull the lower lid down to make a small pocket, and let one drop fall into it without touching the dropper to your eye or lashes. Close the eye gently for a minute. If you use more than one type of drop, leave about five minutes between them, and finish a prescribed antibiotic course even once the eye looks better. Ointments blur vision briefly, so they are often kept for bedtime, and for a wriggling child it can be easier to lay them down, ask them to close the eye, place a drop in the inner corner, and let it run in as they open it.

Which conjunctivitis treatment might the doctor recommend?

Treatment follows the type and the risk: supportive care for most viral cases, restraint with antibiotic drops unless infection is severe, prolonged or higher-risk, antihistamine drops for allergy, and same-day redirection for anything that is not simple conjunctivitis. This is the framework our doctors use, aligned with the cited guidance:^[3]

Treatment options for conjunctivitis

What you can do yourself

Lubricating drops (artificial tears) from any pharmacy soothe all three types and are a reasonable first step. Cool compresses relieve allergic itch; a warm, damp cloth loosens sticky crusting in the morning. Avoid rubbing, which inflames the eye further and spreads infection between eyes. Rest your eyes from make-up and lenses, and take an oral antihistamine if allergy is the likely driver.

Prescription treatment

A prescription is never issued without a consultation. The doctor assesses your eyes first, and for genuinely bacterial cases antibiotic drops or ointment can then be prescribed; which antibiotic depends on what pharmacies stock in your country, and the doctor prescribes accordingly.^[3] For allergic conjunctivitis, prescription antihistamine and mast-cell stabiliser drops step in when pharmacy options fail. What a responsible online doctor will not do is prescribe steroid eye drops: they can accelerate an unrecognised herpes infection of the cornea and raise eye pressure, so they belong with eye specialists after a slit-lamp examination. If your presentation does not fit simple conjunctivitis, you will be told plainly and pointed to in-person care.

When we treat conjunctivitis online, and when we refer you

We treat online: typical viral conjunctivitis needing a firm diagnosis, comfort measures and a stop-the-spread plan; bacterial conjunctivitis, including antibiotic drops when infection is severe, prolonged or higher-risk; allergic conjunctivitis, treated alongside the hay fever or allergy driving it; and reviews when an eye is not settling on the expected timeline.

We refer or redirect you: any red eye with true pain, light sensitivity, vision change, halos or unequal pupils; a painful red eye in a contact-lens wearer, always the same day, because microbial keratitis threatens sight; a red or discharging eye in a newborn baby; eye injuries and chemical splashes; and recurring or atypical red eyes that need slit-lamp examination. In those cases the consultation buys you a clear, safe next step rather than a bottle of drops.
