The infection is usually mild and clears within a few days.
Synopsis: Across Tamil Nadu, doctors report a rise in conjunctivitis or Madras eye, a contagious eye infection causing redness and watering. It spreads through contaminated hands and surfaces, making hygiene and early care important.
A red, watery eye may seem like a small irritation. But across Tamil Nadu, ophthalmologists say clinics are seeing a steady stream of patients with conjunctivitis, commonly known as the Madras eye or pink eye.
The infection is usually mild and clears within a few days. But because it spreads easily through touch, doctors warn that poor hygiene or ignoring symptoms can quickly infect entire households.
Conjunctivitis is an infection of the conjunctiva, the thin membrane covering the white part of the eye and the inside of the eyelids. It can be caused by viruses, bacteria or other microorganisms.

Common symptoms include redness, irritation, watering, discharge and swollen eyelids. The infection usually begins in one eye and may spread to the other.
“It spreads easily when infected tears or secretions come into contact with hands or surfaces,” Dr S Laavanyaa, Consultant – Ophthalmology, SRM Prime Hospitals, Ramapuram, Chennai, told South First.
Crowded places such as schools, buses and offices can make transmission easier, especially when people touch shared surfaces.
Ophthalmologists say conjunctivitis is most commonly viral, and cases tend to increase during warmer months.
“Earlier we mostly saw seasonal surges during summer, though now we do see cases through the year as well,” said Dr Saraswathy K, Consultant Ophthalmologist, Dr Agarwals Eye Hospital.
Doctors also note that the infection spreads faster when people continue attending work or school despite symptoms, often sharing towels, pillows or personal items at home.
In many families, once one person develops conjunctivitis, others may follow within days.
“We often see the infection becoming more intense by the time it reaches the last person in the family,” said Dr Saraswathy.
What you should do
Doctors say most cases settle with proper care, but a medical check is important to rule out complications.
“Plain conjunctivitis usually doesn’t affect vision, but if the cornea is involved, treatment becomes more urgent,” Dr Laavanyaa said, urging patients to avoid self-medication and consult an ophthalmologist if symptoms worsen or persist.
