What Are Halos?

When looking at a light, a halo is a ring with a visible spectrum. The cause of halos are the fraction of light which goes through the lens, but does not clearly make it all the way to the back of the eye. Light entering the eye gets broken up, causing a kaleidoscope effect. Similar to the effect of a halo around the head of an angel as pictured in artwork, this is the halo one would see when there are issues with the lens of the eye.

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.

What Are Some Causes Of Halos?

Some of the simple causes of halos include:

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

Some deeper health issues that may be causing 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.
