You know that uncomfortable moment when an oncoming car’s headlights feel like they’re burning straight into your eyes? If this is happening more often, you’re not imagining it. Night-time glare is a real thing, and it’s worth paying attention to.

Let’s talk about what might be going on and when you should book an eye test.

Why Do Headlights Feel So Bright?

Your eyes work differently in low light. Your pupils dilate to let more light in, which is brilliant for seeing in the dark,but it also means any bright light source becomes more intense. Think of it like opening your curtains wide on a sunny day. More light floods in, but so does the glare.

When you’re young and your eyes are in good shape, your visual system usually handles this pretty well. But as we age, or if certain eye conditions develop, that balancing act becomes trickier. Night-time glare becomes more noticeable, and those halos around streetlights start to appear.

Common Causes of Night-Time Glare

Several things can make you more sensitive to bright lights after dark. Here are the usual suspects.

Cataracts

Cataracts are probably the most common culprit. When the lens inside your eye becomes cloudy, light scatters instead of passing through cleanly. That scattering creates glare and halos, especially around bright lights at night.

Cataracts develop gradually, so you might not notice them during the day at first. But cataract symptoms often show up more obviously when you’re driving after dark. If headlights suddenly seem blinding, it’s worth getting checked.

An Out-of-Date Prescription

Sometimes the answer is simpler than you think. Your prescription might just need updating. Even a small change in your vision can make lights blur and create halos, particularly when your pupils are wide open in the dark.

Regular eye tests catch these changes early. If you haven’t had one in the last two years, book an appointment and get your prescription checked.

Dry Eyes

Dry eyes don’t just feel gritty and uncomfortable. They can also affect how light enters your eye. When your tear film isn’t smooth, light scatters unevenly, causing glare and making night driving harder.

You might notice your eyes feel dry or irritated, especially in air-conditioned cars or after a long day staring at screens. Treating dry eyes can genuinely improve your night vision.

Astigmatism

Astigmatism means your cornea isn’t perfectly curved, so light focuses unevenly. This creates streaks and halos around lights, which become much more obvious at night. If you’ve always had astigmatism, you might be used to it. But if it develops or worsens, night-time glare can suddenly become a problem.

When Should You Worry About Night-Time Glare?

A bit of glare now and then is normal. But certain signs mean you should get your eyes checked sooner rather than later.

If glare is getting worse over weeks or months, that’s a red flag. Sudden changes are even more important. And if you’re struggling to drive safely at night,avoiding it altogether or feeling anxious behind the wheel,don’t ignore it.

You should also pay attention if glare comes with other symptoms. Blurred vision during the day, difficulty reading, or seeing halos around lights all the time (not just at night) could point to something that needs treatment.

What an Eye Test Can Tell You

An eye test does more than just check if you need glasses. Your optometrist will examine the health of your eyes, looking for early signs of conditions like cataracts or glaucoma. They’ll check your prescription, assess your tear film and look at how your eyes handle light.

If night-time glare is bothering you, mention it. Your optometrist can tailor the examination to investigate what’s causing it. They might also recommend specialist eye care if needed.

What You Can Do Right Now

While you’re waiting for your appointment, there are a few practical things that can help. Make sure your windscreen is clean inside and out,smears amplify glare. Consider anti-reflective coating on your glasses if you wear them; it makes a noticeable difference at night.

Avoid looking directly at oncoming headlights. Glance slightly to the left and use the road markings to guide you. And if you’re really struggling, it’s absolutely fine to avoid night driving until you’ve had your eyes checked. Your safety comes first.

According to the NHS, many vision problems develop gradually, so regular eye tests are essential for catching changes early. And the College of Optometrists recommends that everyone should have an eye examination at least every two years, or more often if advised.

Don’t Put It Off

Night-time glare isn’t something you just have to live with. In many cases, it’s fixable,whether that’s updating your glasses, treating dry eyes or discussing cataract surgery when the time is right.

Your eyes change over time, and that’s normal. What matters is catching those changes early so you can do something about them. If driving at night is becoming uncomfortable or unsafe, that’s your cue to get in touch and book an eye test.

You deserve to feel confident on the road, day or night.
