Conjunctivitis may result from infection (bacterial or viral), allergies, or irritation from contact lenses or environmental triggers. Symptoms appear when tiny blood vessels in the conjunctiva become distended, causing redness and discomfort. Identifying the underlying type guides suitable management.

Frequently Asked Questions
We understand that vision correction is a significant decision. Here are honest, transparent answers to the questions we hear most often from our patients.
Conjunctivitis is inflammation of the conjunctiva, the thin membrane covering the white part of the eye and inner eyelids. It can be caused by infection, allergies, or irritation.
Symptoms may include redness, irritation, tearing, discharge, eyelid swelling, or itchiness. Vision is usually unaffected, though temporary blurring can occur due to discharge.
Viral and bacterial conjunctivitis can be contagious. Allergic conjunctivitis is not contagious.
Bacterial conjunctivitis often produces thicker discharge. Viral conjunctivitis may be associated with a recent cold. Allergic conjunctivitis commonly causes itching in both eyes and may occur seasonally. A proper eye examination is needed for accurate diagnosis.
No. Antibiotics are only effective for bacterial infections. Viral conjunctivitis typically resolves with supportive care, while allergic conjunctivitis requires anti-allergy treatment.
Yes. Contact lenses should be discontinued until the condition has fully resolved and your ophthalmologist advises it is safe to resume use.
You should seek medical review if symptoms are severe, painful, associated with light sensitivity or reduced vision, or if they do not improve within a few days.
