Struggling to drive at night on the GT Road or Hazara Motorway? Learn the causes of night glare and halos, from uncorrected power to cataract, and the eye checks and lenses that help.
Many drivers in Haripur notice that driving after dark has become harder: oncoming headlights dazzle, road signs appear late and the edges of the road look blurry. Night driving vision problems are common, and most of them have a clear cause that can be checked and often corrected.
Common Symptoms
- Strong glare or starbursts from oncoming headlights
- Halos around streetlights
- Difficulty reading road signs at night
- Slow recovery after being dazzled
- Feeling tired or tense after night drives
Possible Causes
1. Uncorrected or outdated glasses power
At night the pupil gets bigger, and even small amounts of short-sightedness or astigmatism blur vision more than in daylight. This is called “night myopia”. An updated prescription often helps immediately.
2. Dirty or scratched lenses and windscreens
Scratches and dust scatter light into glare. Clean glasses and a clean windscreen, inside and out, make a big difference.
3. Cataract
A clouding of the natural lens of the eye scatters light and causes glare and halos, often one of the first signs. Learn the cataract warning signs.
4. Dry eyes
An uneven tear film blurs vision, especially with car AC blowing on your face. See our dry eye guide.
5. Retina and other eye conditions
Some retinal and nutritional conditions affect night vision. Diabetes can also affect vision; a diabetic eye check is important for drivers with diabetes.
Do “Night Driving Glasses” Work?
Yellow-tinted “night vision” glasses sold online reduce the total amount of light reaching your eyes. At night you need more light, not less, so they are generally not recommended. What does help:
- An accurate, up-to-date prescription
- An anti-reflective coating on clear lenses
- Treating dry eye or cataract when present
Keep sunglasses for daytime only; never wear tinted lenses for night driving.
Safe Night Driving Tips
- Look slightly to the left edge of your lane when a vehicle approaches, not straight into its lights
- Keep headlights clean and correctly aligned
- Dim your dashboard lights
- Take breaks on long journeys
- Get an eye exam every one to two years, and every year after 60
Frequently Asked Questions
Why is my night vision worse than my day vision?
Larger pupils at night magnify small focusing errors and lens irregularities. An eye test can find the cause.
Can glasses fix halos from cataract?
Glasses may help a little in early cataract, but when glare interferes with driving, surgery by an ophthalmologist is usually considered. We will advise and refer.
