Few eye conditions are as common, as uncomfortable, or as misunderstood as conjunctivitis. Known colloquially as "pink eye," this inflammation of the conjunctiva, the thin transparent membrane that covers the white of the eye and lines the inner eyelids, affects millions of Canadians every year. While it is usually not serious, knowing what type you are dealing with, how to treat it, and when to seek professional help can save you days of discomfort and prevent it from spreading to others.
At Fantastic Glasses in Okotoks, we regularly hear questions from customers about pink eye, especially parents dealing with school outbreaks. Here is a comprehensive guide to understanding and managing conjunctivitis.
The Three Types of Conjunctivitis
Viral Conjunctivitis
This is the most common form and the one most people think of as classic "pink eye." It is caused by the same viruses responsible for colds and upper respiratory infections, particularly adenoviruses. Viral conjunctivitis typically starts in one eye and often spreads to the other within a few days.
Symptoms: Watery, clear discharge; redness; burning or gritty sensation; light sensitivity; swollen eyelids. Often accompanied by cold symptoms like a sore throat or runny nose.
Contagion: Highly contagious. Spreads through direct contact with infected secretions, contaminated hands, towels, pillowcases, and shared personal items. Can remain contagious for up to two weeks.
Treatment: No antibiotic treats viral conjunctivitis. Like a cold, it must run its course, typically resolving in 7 to 14 days. Cool compresses, artificial tears, and good hygiene help manage symptoms.
Bacterial Conjunctivitis
Caused by bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae. Bacterial conjunctivitis can occur at any age but is especially common in children.
Symptoms: Thick, yellow-green discharge that may cause the eyelids to stick together upon waking; significant redness; swelling; a crusty buildup along the lash line.
Contagion: Contagious through direct contact. Children should stay home from school or daycare until 24 hours after starting antibiotic treatment.
Treatment: Antibiotic eye drops or ointment prescribed by a healthcare provider. Most cases improve within 2 to 5 days with treatment, though it is important to complete the full course of antibiotics.
Allergic Conjunctivitis
Triggered by allergens including pollen, pet dander, dust mites, and mould. This type is not contagious and often affects both eyes simultaneously. It is particularly common in Alberta during spring and summer when pollen counts are high.
Symptoms: Intense itching (the hallmark symptom), redness, watery eyes, swollen eyelids, and sometimes a stringy, white discharge. Often accompanied by sneezing, runny nose, and other allergy symptoms.
Treatment: Avoiding the allergen when possible, cold compresses, antihistamine eye drops (available over the counter), and in persistent cases, prescription allergy medications. Wearing sunglasses outdoors can help reduce pollen exposure to the eyes.
When to See a Professional
While many cases of conjunctivitis resolve on their own or with basic home care, certain symptoms warrant prompt professional attention:
- Significant eye pain (beyond mild discomfort or grittiness)
- Sensitivity to light that makes it difficult to keep the eye open
- Blurred vision that does not clear when you blink away discharge
- Symptoms that worsen after 3 to 4 days instead of improving
- Thick discharge suggesting bacterial infection that needs antibiotics
- A weakened immune system from medication or health conditions
- Newborns with any eye redness or discharge (this is a medical urgency)
- Contact lens wearers with red eyes (risk of corneal infection)
Important for contact lens wearers: Stop wearing your contacts immediately if you suspect conjunctivitis. Dispose of the current pair and use a fresh pair only after the infection has fully resolved and your eye care provider confirms it is safe. Contaminated lenses can reintroduce the infection or cause more serious complications.
Preventing the Spread
Good hygiene is the most effective defence against spreading conjunctivitis:
- Wash your hands frequently with soap and water, especially after touching your eyes or face.
- Do not share towels, washcloths, pillowcases, eye drops, or makeup.
- Avoid touching or rubbing your eyes. If you must touch your eye area, wash your hands before and after.
- Replace eye makeup used during the infection. Mascara, eyeliner, and eyeshadow can harbour bacteria and viruses.
- Clean your glasses daily with proper lens cleaner and a microfibre cloth. Frames and nose pads can carry infectious material.
- Launder bedding and towels in hot water and change pillowcases daily during an active infection.
- Disinfect commonly touched surfaces like doorknobs, phones, keyboards, and light switches.
Conjunctivitis and Your Eyeglasses
If you wear glasses and develop conjunctivitis, your frames become a potential vehicle for reinfection. Clean your entire frame, including the nose pads, temple tips, and hinges, with warm soapy water or isopropyl alcohol wipes at least twice daily during an active infection. After the infection clears, give your glasses a thorough deep clean before resuming normal wear.
Glasses wearers actually have a small advantage over contact lens wearers during pink eye season. Glasses create a partial barrier that reduces the chance of touching your eyes and can block some airborne irritants. If you are prone to allergic conjunctivitis, sunglasses with close-fitting or wraparound frames provide additional protection against pollen and other allergens.
Supporting Your Eye Health Year-Round
The best strategy against conjunctivitis and other eye conditions is proactive care. A diet rich in eye-supporting nutrients keeps the conjunctival tissue healthy and supports your immune system. Regular comprehensive eye exams catch problems early and ensure your vision correction is current.
