Prescriptions or over-the-counter eye drops can be used to treat red eyes. It is essential to find the reason behind the disease, as there are some infections that can also cause red eyes.


When to see a doctor

Eye redness is most commonly a mild eye problem and you won’t have to visit an eye specialist. However, you should take the assistance of an eye doctor, if the problem persists and you start experiencing the following symptoms:

  • Redness along with blurry vision
  • Redness along with itching and pain
  • A feeling of pressure in the eyes
  • Extreme pressure in eyes
  • A seasonal eye redness caused by an allergy
  • Discharge from the eyes (green or yellow)
  • Obscured vision or difficulty in seeing
  • Chronic itch or dryness


Usually, red eyes are a cosmetic problem. Eye drops can be used to treat slight irritation, exhaustion and occasional dry eyes with eye drops. If the eye redness is caused because of an underlying eye disorder, drops won’t be enough to treat the illness.

While over-the-counter eye drops are the most common solution for red eye treatment, you can also use prescription remedies to get rid of the eye disorder.
