Halos Around Lights —
What They Mean & What You Can Do
Halos or “glowing rings” around headlights, streetlights, or lamps are common — especially at night or while driving. Many causes are harmless, but halos may also indicate early cataracts, dry eye, or refractive changes that can be treated.
MiVision offers same-week appointments in our Saginaw Office for glare, halos, and night-driving problems.
Common Causes of Halos Around Lights
Cataracts
-
Early cataracts scatter light, creating glare, halos, and starbursts.
-
Symptoms often worsen at night or in low-contrast settings.
-

Dry Eye Syndrome
-
An unstable tear film can cause smearing, halos, and fluctuating clarity.
-
Symptoms often worsen with screen use or wind exposure.

Astigmatism or Outdated Prescription
-
Even small refractive errors can turn points of light into rings or streaks.
-
Halos may worsen when driving at night.
Presbyopia / Age-Related Vision Changes
-
After age 40, reduced contrast sensitivity can make nighttime glare more noticeable.
-
Halos may worsen in dim lighting.
Post-LASIK or PRK Healing
-
Halos are common during the healing process.
-
Most improve within weeks to months.
Contact Lens Issues
-
Dry, old, or poorly fitting lenses scatter light and cause haloing.
-
Switching to fresh lenses or better materials often helps.
Corneal Swelling or Edema
-
Rare, but can cause rainbow-colored halos—often needs evaluation.
Night Driving Challenges
-
Issues with glare, contrast, or early cataracts often worsen halos at night.

How MiVision Evaluates Haloes
Your exam may include:
-
Refraction (glasses/contact lens check)
-
Dry eye assessment
-
Cataract evaluation
-
Corneal topography or tomography
-
Night glare testing
-
Retinal exam if indicated
Our goal is to identify exactly what’s causing halos and recommend the right treatment.

Correcting astigmatism or small refractive errors often reduces halos dramatically.

A new prescription can sharpen night vision.
-
