Opticrom Eye Drops contain an active ingredient called sodium cromoglicate 2%. This is part of a group of medicines called anti-allergics. They treat allergic conjunctivitis, a condition triggered by hay fever, house mites and other allergies. The allergens can irritate eyes, making them red, watery, itchy, and puffy.
Opticrom eye drops should be used by applying one or two drops into each eye four times a day.
