Why Do I See Halos Around Headlights?

Answer first

Halos around headlights are perceived rings or blooms caused by light scattering before it forms a crisp retinal image. Drivers notice them most on dark roads with high-contrast oncoming lights.

Cause categories

Tear-film irregularity, uncorrected astigmatism or residual refractive error, corneal swelling/issues, early cataract themes, certain postsurgical optical discussions, and less commonly other media or retinal problems. Migraine visual phenomena are usually a different time-limited pattern.

Urgency nuance

Chronic mild halos: schedule an exam and update refraction. Sudden painful red eye with rainbow halos and nausea is a classic urgent ophthalmic pattern that should not wait. Flashes/floaters/curtain remain vitreoretinal urgency cues even if halos are your main complaint.
