If your eyes have been red for 3 days despite using Exocin eye drops (Ofloxacin), the cause may not be bacterial and could be viral or allergic. You should stop self-medicating and get your eyes examined by an eye doctor to identify the exact cause and receive appropriate treatment. Avoid rubbing your eyes and do not use contact lenses or eye makeup until the redness settles. Seek medical care promptly if you develop pain, blurred vision, or sensitivity to light.
