Night driving presents unique challenges for everyone, but for those with astigmatism, it can feel particularly challenging. The added complexity of reduced visibility and glare from lights often amplifies the effects of astigmatism, making nighttime journeys less comfortable even if you’re wearing glasses or contact lenses.
Astigmatism affects night driving by distorting lights and reducing clarity, all of which can compromise safety. But you don’t have to resign yourself to staying in after the sun goes down just because you have astigmatism. With an eye exam, we can help you drive confidently—even at night.
What Is Astigmatism?
Astigmatism is a common vision condition caused by an irregularly shaped cornea or lens. Instead of being round like a basketball, the cornea takes on an uneven curve, similar to a football. This irregular shape alters how light enters the eye, causing it to focus unevenly on the retina.
While myopia (nearsightedness) causes blurry distance vision and hyperopia (farsightedness) causes blurry near vision, astigmatism can affect clarity at all distances.
Some signs of astigmatism include:
- Blurry or distorted vision
- Eye strain or discomfort, especially after prolonged visual tasks
- Squinting to see clearly
- Difficulty seeing fine details
Astigmatism can pose additional challenges when it comes to night vision. When dim lighting causes your pupils to dilate (become larger), more of the irregular curvature in the eye becomes exposed. In many cases, this exacerbates the irregularities caused by astigmatism, making objects appear more blurry or creating visual effects like streaks and halos around lights.
How Optometrists Address Astigmatism:
Many people struggle with astigmatism. It’s a particularly complex condition because it can happen alongside other conditions, such as nearsightedness or farsightedness. Much like these other conditions, we can help you manage them effectively with:
- Prescription glasses or contact lenses: Corrective lenses compensate for the eye’s uneven curvature, improving clarity. Modern techniques even allow people with irregular corneas due to astigmatism to enjoy the benefits of contact lenses.
- Refractive surgery: Procedures like LASIK can reshape the cornea to correct the irregularity.
Astigmatism & Night Driving
Driving in the dark can be challenging at the best of times. But, it can be particularly complicated for those with astigmatism. The visual distortions you experience during the day often stand out more because of the strong contrast between bright lights and the dark areas around them.
Here are some common issues people with astigmatism face at night:
- Distorted lights: Headlights, traffic lights, and streetlamps may appear distorted with halos or streaks. These distortions can make it harder to judge distances or identify objects on the road.
- Increased sensitivity to glare: Bright lights from oncoming traffic or reflective surfaces overwhelm your vision, causing discomfort or momentary blindness.
- Reduced depth perception: Astigmatism can prevent you from accurately gauging distances in low-light conditions. This makes merging onto highways or navigating intersections more difficult.
- Blurry peripheral vision: The cornea’s uneven curvature may blur or distort your peripheral vision, reducing your ability to spot hazards like pedestrians or cyclists at night.
Tips for Safer Night Driving with Astigmatism
Night driving with astigmatism doesn’t have to be overwhelming. With the right adjustments and tools, you can hit the road with confidence. Here’s how:
Wear the Right Eyewear
Invest in high-quality prescription glasses or contact lenses specifically designed for astigmatism. Consider lenses with an anti-glare coating to minimize reflections and improve clarity at night.
Keep Your Lenses Clean
Just like splatters on your windshield, smudges or dirt on your lenses can worsen visual distortions. Regularly clean your glasses with a microfiber cloth and the appropriate lens cleaner to avoid scratching the lenses.
Reduce Glare Inside the Car
Much of nighttime driving comes down to safe driving techniques. These can benefit everybody, not just those with astigmatism. Combat glare with these steps:
- Turn down the brightness on your internal displays to make them less distracting
- Most cars have a night-driving mode for their rearview mirror to reduce glare from other car’s headlights. Consult your owner’s manual if you’re unsure how to use this function
- Avoid looking directly into oncoming headlights—focus slightly to the side instead
Don’t Drive When Tired
Fatigue worsens eye strain and delays reaction times. If you feel tired or notice your vision blurring after driving for a while, pull over and take a short break to rest your eyes.
Get Regular Eye Checkups
Schedule yearly eye exams to keep your prescription up-to-date. When you visit us, we can also recommend lens options or coatings specifically tailored to your night driving needs.
