Redness, discharge, irritation and stickiness in the eyes may occur because of conjunctivitis, which may develop from a viral or bacterial infection, an allergy or exposure to dust and pollution. Bacterial conjunctivitis often causes yellow or thick discharge, while viral infection may cause watery eyes and irritation. The eye can also feel itchy, burning or uncomfortable when blinking. Keeping the eye clean with sterile cotton and clean water may help remove discharge and reduce irritation. Avoid rubbing the eyes, sharing towels, or touching the eyes repeatedly because the infection can spread easily. Doctors may advise antibiotic eye drops if bacterial infection is suspected, while lubricating drops or anti-allergy medicines may help in other types of conjunctivitis. Proper handwashing and taking breaks from screens for a while may also improve comfort. Contact lens use should be avoided until the eye has completely healed. Seek medical care if vision becomes blurred, swelling increases, severe pain develops, or the redness spreads rapidly.

Redness and yellow discharge from the eye in a 36-day-old baby can be caused by blocked tear ducts, a bacterial eye infection, irritation, or newborn conjunctivitis. In small babies, sticky yellow discharge may collect repeatedly because tears do not drain properly, and the eye can appear red or watery. Eye infections in newborns should be assessed carefully because babies at this age are very sensitive to infections. Cleaning the eye gently with sterile cotton or clean gauze dipped in lukewarm boiled water may help remove discharge safely. Always wipe from the inner side of the eye outward using a fresh, clean cotton each time. Avoid using over-the-counter eye drops without pediatric advice because some medicines may not be safe for newborns. A paediatrician or eye specialist may prescribe antibiotic eye drops or ointment if infection is confirmed. Gentle tear duct massage may also help if blockage is contributing to the discharge. Seek urgent medical care if swelling increases, fever develops, the baby feeds poorly, or redness spreads rapidly.
