How Vision Impacts Night Driving - Night Driving Tips and Tricks

If you’re like me, you’ve probably noticed that it’s more difficult to drive at night than during the day time. You might have a hard time seeing road signs and lights may appear really bright. Personally, I avoid driving at night because of these issues.

In this video, I’ll address why it’s more difficult to see while driving at night. Watch until the end where I review night driving tips and tricks on how to safely drive at night.

Eye diseases that cause poor night driving vision

Age-related cataracts, glaucoma, and macular degeneration are all eye diseases that can impact your vision while driving at night. Another less common reason for poor night driving vision is an inherited condition called retinal dystrophy.

Just remember that all of these conditions can only be adequately diagnosed with a comprehensive eye exam.

Dry eye disease and night driving

One of the most common reasons for not being able to see well at night time is dry eye disease. Unfortunately, dry eye disease affects upwards of 30 million Americans and is characterized by a decreased quality and quantity of the tear film.

Since light hits the tear film before it hits the cornea, dry eye disease can really affect your vision.

Vision correction and night driving

Do you wear glasses or contact lenses? Did you know that some people wear distance only night driving glasses to see better at night?

Uncorrected myopia (nearsightedness) or astigmatism can make driving a night a real challenge. In fact, your pupil gets bigger in low light situations to allow more light in so you can see. If your prescription is off, or vision is uncorrected, this can lead to an increase in halos and glare. Therefore, before you get behind that wheel, make sure that your glasses prescription is up to date.

My top tips and tricks for ensuring that you have good night driving vision

  1. Always use preservative-free artificial tears about 15 to 20 minutes before you get behind the wheel. Please make sure that you are not using any gels or ointments before you get behind the wheel because these can actually blur your vision for a short period of time.
  2. Please make sure that your headlight covers and your windshield are clean.
  3. Make sure that you update your glasses prescription with your eye doctor every year.
  4. Make sure that your eyes are dilated at every eye exam so that we can look for those conditions such as cataracts, glaucoma, macular degeneration, and other retinal diseases.


In the end, it’s clear that it’s more challenging to drive at night than during the day. While there are a number of factors that make night driving difficult, many of them you can control.
