Night Driving Glare Worse After the Time Change? Here's Why (Nashville)

Once daylight saving time ends, most of the Nashville commute home happens in the dark. If headlights suddenly look like starbursts, streetlights have halos, or you're squinting at road signs on I-440, you're not imagining it. Night driving glare is one of the most common things we hear about this time of year, and in many cases it's very fixable.

Why glare gets worse at night

In the dark, your pupils open wide to let in more light. A bigger pupil uses more of the edges of your eye's optics, so small imperfections that don't bother you in daylight start to show up as halos, streaks, and blur. That's why someone can see "fine" all day and still struggle on the drive home.

Common causes of night driving glare

• A small, uncorrected prescription. Even a little nearsightedness or astigmatism can make lights look streaky at night. Astigmatism in particular causes that starburst look around headlights.
• An outdated prescription. Eyes change. If it's been more than a year or two since your last exam, your glasses may be a step behind.
• Glasses without a good anti-reflective coating. Uncoated lenses reflect light off the front and back surfaces, which adds extra glare and ghost images. Scratched or worn coatings make it worse.
• Dry eye. A dry, uneven tear film scatters light. If your vision gets better after you blink, dry eye may be part of the problem. Heaters and cold, dry winter air tend to make it worse.
• Early cataracts. Glare and halos at night are often one of the first signs of a cataract, especially after 50.
• Dirty windshields and lenses. Simple, but real. Clean the inside of your windshield too — the film that builds up there spreads light.

Do "night driving glasses" help?

Yellow-tinted "night driving" glasses are sold everywhere, but they don't improve how well you see at night. Any tint reduces the amount of light reaching your eyes, which is the opposite of what you need in the dark. The better fix is an up-to-date prescription with a quality anti-reflective coating.

What we do about it at Elite Eyecare Nashville

A comprehensive eye exam with Dr. Nathan Lipe checks for all of the causes above in one visit: your prescription (including small amounts of astigmatism), the health of your tear film, and early signs of cataracts. If new glasses are the answer, we have an in-office lens lab and about 600 lenses in stock, so many single vision prescriptions can be made the same day — with anti-reflective coating. If dry eye is part of the problem, we can talk through dry eye treatment options.
