Most patients with red eye disease have a course of illness lasting about 7 to 10 days, primarily treated with anti-inflammatory and anti-swelling medications. Some young and middle-aged patients may develop concurrent keratoconjunctivitis, which results in a slower recovery that could last one to two months. However, the majority of patients can recover within about seven days through medication, rest, and increased fluid intake. It is important to maintain good eye hygiene and follow a light diet, avoiding spicy or irritating foods.
