The first time you notice it, you think your windscreen’s just dirty.
Headlights blur into glowing starbursts, streetlamps grow hazy rings, and you lean forward, squinting, like that’ll make the light behave.
Some people shrug it off. Others start rearranging their lives, avoiding certain roads, driving less after dark, sticking to the well-lit main streets.
The tricky part? Sometimes it’s just how eyes react to light. Other times, it’s a signal you shouldn’t ignore.
Halos vs Glare, Not the Same Thing
Halos are the circles you see around lights at night, like every headlamp has grown a faint rainbow crown. They stand out more when your pupils are wide, which is exactly what happens in dim light.
Glare’s a different beast. It’s light that bulldozes the detail you need to see, high beams that make the whole lane disappear, or a low sunset that forces you to look away until the angle changes.
Both can mess with night driving. Neither should be written off without at least a closer look.
Common Reasons They Show Up
Some causes are temporary. Others stick around until you fix the root of the problem.
Cataracts: A cloudy lens scatters light before it even reaches the back of your eye. Colours can fade, headlights bloom, and signs take longer for you to read. This is one of the most common reasons people tell us they “just don’t drive at night anymore.”
Refractive errors: Astigmatism symptoms, including short-sightedness and long-sightedness, can bend and scatter light, creating halos and flare. Out-of-date glasses or contact prescriptions make it worse.
Dry eyes: An uneven tear film bends light in ways it’s not supposed to, especially in low-light settings. People often come in for sore eyes or irritation, but mention glare as an “oh, and…” in the last minute of the appointment.
Corneal changes: Conditions like keratoconus or scarring change the way light focuses. Regular lenses can’t always correct it, but specialty ones often can.
Post-surgery recovery: LASIK, PRK, or cataract surgery can cause temporary halos and glare while your eyes settle. For most, it fades. For some, it needs a tweak.
When to Treat It Like an Emergency
Not every halo is a red flag. But some are.
- Sudden halos plus eye pain or nausea? Possible angle-closure glaucoma, don’t wait.
- Flashes of light or a shadow across your vision? It could be a retinal tear.
If you’re not sure, you’re better off getting checked now, not later.
Why Night Driving Makes It Worse
It’s not just that it’s dark. It’s the constant switch between black road and bright lights. Your pupils open wide to drink in more light, and all the imperfections in how that light’s handled get magnified. Add in a dirty windscreen, wet bitumen, or scratched glasses and every light source blooms larger than it should.
Things You Can Do Tonight
Clear the view: Wipe the inside of your windscreen, the outside, and your headlights while you’re at it. Give your glasses a proper clean too. Even the thinnest film of dust or smudge can turn a pinpoint light into a fuzzy glow.
Pick the right lenses: Glasses with an anti-reflective coating take a lot of the sting out of glare from streetlamps and high beams. Some drivers like the extra contrast from yellow-tinted lenses. They help in certain conditions, but they’re no cure-all.
Fixing the Root Cause
Sometimes the answer’s simple. Other times, it’s a bit more involved.
An out-of-date glasses or contact lens prescription? That’s an easy win. One tweak, and the light starts landing where it’s supposed to instead of scattering across your vision.
Dry eyes are trickier. A good lubricating drop might do the job, but if the problem’s been hanging around, you might need an in-practice treatment to smooth out the tear film. That’s what stops every headlight from blooming into a halo.
Cataracts are different again. They creep in slowly, so it’s tempting to wait. But the people who deal with them early are the ones who usually get sharper, safer night vision back.
And then you’ve got specialty contact lenses, built for certain corneal conditions. They don’t shout about it, but they quietly change how light enters your eyes, cutting down glare before you even notice it was there.
The Confidence Factor
Losing night vision confidence doesn’t just affect how you see; it changes how you live. You start leaving places early to get home before dark. You stick to familiar streets. You pass on events because the idea of the drive is exhausting before it’s even happened.
It doesn’t have to stay that way. Most causes of glare and halos can be treated, reduced, or managed, often with far less effort than people expect.
Bottom Line
Halos and glare don’t always mean something’s seriously wrong. But if they’ve started showing up more often, or if you’ve quietly adjusted your driving just to work around them, it’s worth paying attention.
At EyeSelect, we’ve spent decades helping people get their night vision back on track. Sometimes that’s removing a cataract before it steals more clarity. Sometimes it’s smoothing out a rough tear film so headlights stop blooming into hazy rings. And sometimes, it’s as simple as getting the right lenses in front of your eyes.
