What is Pink Eye?
Pink eye, also known as conjunctivitis, is an inflammation or infection of the conjunctiva, the thin clear tissue that covers the white part of the eye and the inside of the eyelid.
It is a common eye condition that can cause redness, itchiness, discharge, and irritation.
When irritated or infected, the tiny blood vessels in this tissue become more visible, causing the eye to appear pink or red. There are a few different types of conjunctivitis, and each can have different causes and treatments.
While it’s often mild and treatable, some types can spread easily, especially in classrooms, shared spaces, and during cold and flu season.
Not every red or irritated eye is pink eye. Some eye conditions can look very similar to conjunctivitis but may be vision-threatening and require urgent treatment.
If you're experiencing symptoms or aren't sure what's causing your red eye, it's important to contact your optometrist for a proper diagnosis.
Common symptoms of pink eye can include:
Red or pink eyes
Itching or irritation
Watery eyes
Sticky or gooey discharge
Crusting around the eyelids, especially in the morning
Swollen eyelids
Sensitivity to light
A gritty or burning sensation in the eye
Common causes of pink eye can include:
Touching or rubbing infected eyes
Sharing towels, pillowcases, or eye makeup
Contact with contaminated surfaces
Close contact with someone who has viral or bacterial conjunctivitis
What type of conjunctivitis do you have?
Viral
Often linked to colds or respiratory infections, viral pink eye spreads easily and is highly contagious.
Bacterial
This type is caused by bacteria and is usually associated with thick or sticky yellow-green discharge.
Allergic
Triggered by allergens like pollen, dust, or pet dander. Allergic pink eye is not contagious and often affects both eyes.

Preventing pink eye
Good hygiene habits can help reduce the risk of spreading conjunctivitis:
Wash your hands frequently
Avoid touching or rubbing your eyes
Don’t share towels, pillows, or eye products
Long-term corticosteroid use
Clean contact lenses properly and replace lens cases regularly
Stay home when symptoms are severe or highly contagious
Managing and treating pink eye
Treatment depends on the type of conjunctivitis you have. Some cases clear on their own, while others may require prescription eye drops or medication. Your optometrist can determine the cause and recommend the right treatment plan.
It’s best to book an appointment if:
Symptoms last more than a few days
Vision becomes blurry
You experience pain or light sensitivity
Discharge becomes severe
Symptoms continue returning
You’re unsure whether it’s pink eye or another eye condition
While waiting for an appointment, you may find temporary relief by:
Applying warm compresses
Using lubricating artificial tears
Avoiding rubbing your eyes
Pausing contact lens wear until symptoms improve
Early detection can help prevent complications and reduce the spread to others.

FAQs
What is the first sign of cataracts?
The earliest sign is usually mildly blurry or hazy vision, especially when reading or driving at night. You may also notice glare from headlights or sunlight and need brighter light for close-up tasks.
What is the main cause of cataracts?
The most common cause is age-related protein breakdown in the eye's natural lens. Diabetes, smoking, long-term steroid use, eye injury, and prolonged UV exposure can speed up cataract development.
Can cataracts be cured without surgery?
Cataracts cannot be reversed by drops, supplements or lifestyle changes. In early stages, updated glasses, anti-glare lenses and brighter lighting can manage symptoms. Cataract surgery is the only treatment that removes them.
At what stage should cataracts be removed?
Surgery is typically recommended when cataracts interfere with daily activities such as reading, driving, or working — not at a specific "ripeness." Your optometrist will help you decide based on your visual needs.
Can young people get cataracts?
Yes. While most cataracts are age-related, congenital cataracts, eye trauma, diabetes, certain medications and high myopia can cause cataracts in children and younger adults.
