Glare and Halos

Glare and halos are both eye symptoms that some people experience around bright lights. Halos show up as bright circles around a light source. Glare is light that interferes with your vision, making it difficult to see or sometimes making your eyes water.

These symptoms can show up at any time of the day. Halos often appear at night when the area around the lights is dim or dark, such as while driving at night.

Several conditions can cause glare and halos, such as aging or certain types of eye surgery. Treatment may involve taking care of the underlying cause. Other times, you may need to avoid driving at night if the glare and halos interfere with your driving.

Causes of Glare and Halos

Several things can cause glare and halos, including:

  • Cataracts
  • Refractive surgery, such as LASIK
  • Aging
  • Common eye problems such as nearsightedness, farsightedness or astigmatism
  • Pupil dilation during an eye exam
  • Artificial lens implants used to treat cataracts (intraocular lenses, or IOLs)

When your eyes are heavily dilated during an eye exam, the light passes through the outer edge of the lens. This allows the light to bend (refract) differently as it passes through. This can cause glare.

If you have had LASIK or another kind of refractive surgery, you may experience glare or halos around light for several months after the procedure.

Treatment for Glare and Halos

Before deciding on a treatment, your eye doctor will perform an eye exam to determine what’s causing the glare and halos. Possible treatments include:

  • Watching and waiting to see if the glare and halos clear up on their own, such as after LASIK surgery
  • Medicated eye drops
  • Treatment for cataracts
  • Wearing sunglasses during the day to reduce glare
  • Using the visor on your car to keep direct sunlight out of your eyes
  • Correcting your vision with glasses or contact lenses

Reviews From Our Satisfied Patients

  • "I thoroughly enjoyed my visit! I see an optometrist every year and I received care at her office that I've never received anywhere! I had my eyes dilated for the 1st time to make sure everything was ok. It was offered to me & covered by my insurance. I realize the importance of my vision and was very pleased with the care I received!"

  • "First of all, the atmosphere was welcoming....(very important to me). The receptionist worked with us and was very patient due to the fact we haven't seen an optometrist in a while....and Dr. Norwood took extra time out to explain things that was unclear to me (for myself and my child). I expect the type of care she provided.
    My last experience (elsewhere) was rough, which is why it took me so long to see another eye Dr.
    Dr. Norwood is a great example for all optometrists and her staff as well. Thanks again..."
