What Causes There To Be Halos Around Lights In One's Vision?

Dr. Jim Martin 12/04/2017

Vision issues can be a sign of larger health problems. One common issue we hear from patients is that of seeing a halo around lights, especially at night. This can be caused by tired eyes or could be a sign of a more serious problem.

What Are Halos?

Have you ever looked at a streetlight late at night and spotted a hazy ring around the lightbulb? This is a halo, or a ring with a visible spectrum that forms around bright lights. Many refer to the phenomenon as a halo because it resembles the head of an angel as pictured in artwork.

You will see halos when a fraction of light goes through the lens of your eye but does not make it all the way to the back of your eye.  Light entering the eye gets broken up, causing a kaleidoscope effect. While the presence of halos alone doesn't indicate serious health problems, it can be a symptom of underlying eye conditions.

What Is The Lens Of The Eye?

The lens is located at the front of the eye. This area is often clear. Change in the shape of the lens affects vision, allowing the patient to focus both near and far. Due to aging, the lens can become clouded, as in cataracts. Additionally, an astigmatism, or irregular shape to the eye or lens, can cause visible halo effects.

Some of the simple causes of halos include:

      • Excessive tearing
      • Corneal edema due to overuse of contact lenses
      • Night vision issues and dry eyes

Some more serious health issues that might cause halos include:

  • Glaucoma
  • Cataracts
  • Pigment dispersion syndrome
  • Drugs

It is important to work with your optometrist to determine the cause of the halos. Some serious conditions can be treated easily when detected early on.
