Night Driving Glare

Ever wonder why headlights turn into rings at night? Stick around for the single tip that can clear them up.

Why glare spikes at night

When it’s dark your pupils open wide, letting in more light. That larger opening uses the whole lens and cornea, so any tiny scratch or haze gets magnified, turning a point light into a glow or star.

Check your prescription

A small change in your glasses prescription that you don’t notice in daylight can show up at night, especially if you haven’t had an eye test in years. Night myopia can make you a bit more short-sighted after dark.

Clean your view

First, give your windshield a good clean inside and out with a glass cleaner and a microfiber cloth. Then wipe your glasses with a drop of mild soap and a soft cloth. Finally, dim your dashboard and phone screen so they don’t shrink your pupils.

Dry eyes & scratches

Don’t forget the inside of the windscreen, a greasy film from the dashboard, smoke or breath catches every oncoming light. Scratched lenses do the same, and dry eyes act like a smeared lens, especially when the AC blows or you blink less.

Anti-reflective coating

An anti-reflective coating can cut the ghost images you sometimes see on your lenses, making night driving a bit more comfortable. But it won’t fix a cataract, an outdated prescription, or dry eyes, and a scratched coating can be worse than none.

Yellow glasses myth

Yellow or amber night-vision glasses promise to cut glare, but they actually reduce the amount of light reaching your eyes, which is the last thing you need after dark. Most eye specialists advise against using them for driving.

The one tip tonight

The most effective thing you can do tonight is give your windshield a thorough clean, both inside and out, with a microfiber cloth. A clear glass removes the glare source before anything else.
