The holiday season can present distinct challenges for individuals with astigmatism.
Experiencing a variety of lights and decorations can truly enhance your holiday mood. However, one aspect that can dampen your festive spirit is driving after dark if you have astigmatism.
Astigmatism is characterized by an irregular curvature of the eye, which leads to blurred vision. This condition is classified as a type of refractive error—around 150 million Americans are affected by refractive errors.
“Holiday lights can have a negative effect on individuals with astigmatism due to the unique way light bends in their eyes,” stated James Kelly, MD, an ophthalmologist practicing in NYC and Long Island.
He described astigmatism as a prevalent eye issue where the cornea or lens is shaped irregularly, causing light rays to bend unevenly, resulting in blurred or distorted vision.
Patients with astigmatism may see holiday lights as blurry or exhibit an elongated starburst effect, according to Jennifer L. Stone, OD, an optometrist based in Baltimore, who spoke to Health.
“This glare can disrupt the sharp details of their vision, affecting their ability to see objects both at a distance and up close,” she explained.
It’s essential to recognize that there are varying degrees of astigmatism, and since it is a common health issue, many individuals may experience few to no symptoms.
“Not correcting astigmatism can lead to more glare from any light sources, and holiday lights are no exception,” noted Timothy McCulley, MD, a professor and chair of ophthalmology at UTHealth Houston. “Generally, this isn’t to a degree that is significantly impactful.”
There are several ways in which the abundance of holiday lights might heighten risks for those with astigmatism, along with suggestions for safe driving this holiday season.
Due to the increased number of lights during this season, individuals with astigmatism might encounter additional health issues.
Kelly noted that heightened glare is the primary concern.
With so many bright and flashy holiday lights, experiencing increased glare is common. For someone suffering from astigmatism, this glare may be more intense and distracting, potentially hindering their ability to view the road clearly.
Kelly elaborated that astigmatism can already lead to “dizzying” or “shaky” vision in more severe cases. When holiday lights include moving or flashing elements, they can be even more disorienting for the eyes and could result in accidents or distractions while driving.
Furthermore, halos and starburst effects surrounding lights can complicate the ability to distinguish between various lights, including traffic signals, streetlights, and decorative displays.
The contrast between different light colors (like vibrant holiday hues) can also obscure the visibility of crucial traffic signs. This effect may intensify on wet roads that reflect lights—these reflections can blur vision and enhance glare.
“To mitigate these risks, individuals with astigmatism should ensure they have an accurate prescription for their glasses or contact lenses, consider anti-reflective coatings for their eyewear, and exercise extra caution when driving at night through areas adorned with heavy holiday decorations,” Kelly advised.
The added visual challenges from holiday lights can lead to faster onset of eye strain and fatigue for drivers with astigmatism, potentially affecting their focus and response times while driving.
“If the visual disturbances are pronounced, it may be wiser to avoid driving at night under these circumstances or to choose alternate routes that steer clear of decorations,” Kelly recommended.
Tips for Driving Safely in Darkness When You Have Astigmatism
Individuals with vision impairments or concerns, particularly regarding night driving coupled with numerous lights, should keep certain safety recommendations in mind.
Kelly suggests that patients with astigmatism should emphasize the following:
Recognize Your Vision Limitations
Individuals dealing with vision issues should understand how their specific conditions influence their night driving abilities. Issues such as astigmatism, myopia (nearsightedness), presbyopia (age-related farsightedness), and cataracts can all impact clear vision in low-light settings.
Schedule Routine Eye Exams
Kelly stressed the importance of regular check-ups with an eye care professional. This ensures updated prescriptions are obtained and provides tailored advice for safe nighttime driving.
Emphasize Proper Eyewear
It’s vital to ensure your eyewear is current for safety, regardless of whether you have astigmatism.
“If glasses are prescribed, ensure they are in good condition and wear them in high-glare situations,” Stone advised.
In addition to glasses, if you are using contact lenses, it’s important to check that they’re not causing dry eyes, or that you manage any dryness with appropriate drops. Using improper treatments can further degrade your eyesight.
Adjust Your Driving Behaviors
Recognizing that holiday lights can make driving conditions worse, it’s crucial to stay mindful of diminished visibility and focus on enhancing reaction times. Maintain a greater distance from the vehicle ahead to ensure you have sufficient time to respond.
Minimize Driving Distractions
In addition to changing your driving behaviors, it’s essential to limit internal distractions within your vehicle, such as bright dashboard lights, screens, and loud music. Stone suggests that people降低车载控制台亮度以及额外的设备和内部灯光。
This allows you to concentrate more on the road and the surroundings.
Regularly Clean Your Windshield and Headlights
Keeping your windshield, windows, and headlights clear can significantly contribute to safe driving. Dirt or smudges can intensify glare and hinder visibility.
“Make sure your windshield is spotless, both inside and out, to minimize dirty reflections and eliminate additional glare sources within the vehicle,” Stone advised.
Take Breaks for Your Eyes
If you experience eye strain or fatigue, it’s vital to take a break. Driving while your eyes are tired or strained can severely compromise your ability to respond quickly.
Recognize When You Shouldn’t Drive
If you believe your vision seriously hampers your ability to drive safely at night, especially considering the added distraction of holiday lights, it may be wiser to refrain from driving under those circumstances.
Also, be aware that “the typical astigmatism is unlikely to cause significant glare. If glare is a concern, it’s more probable to be due to cataracts,” McCulley noted. “If you don’t feel secure driving, it’s better not to.”
Did you know that sending or reading a text while driving diverts your eyes from the road for 5 seconds? At a speed of 55 mph, that’s akin to driving the entire length of a football field with your eyes closed. Texting is one of the primary contributors to distracted driving, which is a prevalent cause of car accidents in the United States.
Recent data from the National Highway Traffic Safety Administration (NHTSA) indicates that distracted driving claimed 3,308 lives in 2022. With such a high number of fatalities due to distracted driving, it is essential to understand how we can maintain our focus on the road.
Acknowledging the Dangers of Distracted Driving
Distracted driving encompasses more than just phone use while driving; it includes any activity that diverts your attention from the wheel. It’s important to understand that actions such as eating, adjusting your GPS, or changing your music can also take your eyes off the road momentarily. While these tasks might seem minor, they can significantly impair your reaction times and often lead to accidents. To help keep your attention on the road, consider the following:
Utilize Technology Effectively
While technology can be a distraction when driving, it can also serve as a tool to help maintain our focus on the road:
Prepare Your GPS Before Driving: To reduce unnecessary screen use, program your destination before you start driving, or utilize hands-free features to set up your route. This way, you can avoid fiddling with your device while driving, minimizing instances where your eyes are off the road.
Employ Apps That Block Incoming Texts and Calls When Driving: Functions on your phone, like “Do Not Disturb” or specific driving applications, can prevent notifications from appearing on your phone while driving, allowing you to focus solely on driving.
Organize Your Space
Keeping your vehicle’s interior well-organized can greatly reduce the need to search for items while driving. Ensure that all essential items, such as sunglasses, toll money, or drinks, are within easy reach and stored in a secure place to prevent them from shifting while you drive.
Secure Children and Pets
If you are traveling with children or pets, always ensure that children are properly buckled in and that pets are situated in a designated area or secured in a pet carrier. Unsecured pets or children moving around the car can create a considerable distraction and divert your attention from the road for extended periods.
Maintain Focus on the Road
Although it may seem straightforward to keep your eyes on the road, sometimes it can be challenging to maintain your focus on what’s in front of you. If you find it difficult to stay focused, consider:
Practicing the 20-20-20 Rule: During road trips and extended drives, it’s easy to enter a state known as Highway Hypnosis. This can lead to a loss of focus on your destination and activities. In such situations, try employing the 20-20-20 rule. Every 20 minutes, look away from the road at an object 20 feet away for approximately 20 seconds. This can alleviate eye strain and help keep your mind engaged and vigilant.
Adjust Your Vehicle Settings Before You Leave: Make it a habit to configure all your vehicle settings prior to setting off. This includes adjusting your mirrors, seat, climate controls, and audio system before leaving.
Avoid Looking at Accident Scenes or Billboards: Observing car accidents and billboards can divert your attention from driving and are among the most frequent distractions encountered while traveling.
Educating Young Drivers: Young drivers, particularly teenagers, are more vulnerable to distractions while driving. Therefore, it’s essential to model good behavior and adhere to safe driving practices. Additionally, it’s crucial for young drivers to grasp the significance of safety while driving and to foster a secure environment for all road users.
By incorporating these suggestions, you as a driver can notably reduce the likelihood of causing or getting involved in an accident due to distracted driving. Always keep your attention on the road, as anything can occur in the brief moments you look away.

Visibility of hazards significantly contributes to road traffic collisions (RTCs). At night, visual performance declines; for instance, sensitivity to contrast is reduced, and the ability to perceive motion is affected. Road lighting is established to counteract this visual impairment and enhance a driver’s capability to spot and recognize potential hazards that vehicle headlights might not reveal.
Previous research has examined how variations in lighting conditions influence detection and identification abilities. Some studies conducted in labs involve abstract targets like Landolt rings or discs presented on screens. Typically, it is noted in peripheral detection studies that increased luminance and the scotopic/photopic (S/P) luminance ratio enhance detection rates and shorten reaction time to spotting the target.
Eventually, the advantages of these enhancements reach a limit, where further boosts in luminance or S/P ratio yield little to no improvement in visual performance, and this threshold helps estimate optimal lighting conditions.
In these studies, participants are required to concentrate on specific tasks as directed by the experimenter. For instance, they may be instructed to focus on a fixed point and press a button when they perceive a target in their peripheral vision. This setup does not accurately mimic real driving scenarios.
A driver’s visual focus is dynamic, as they must manage various tasks—such as steering, controlling speed, monitoring other vehicles, and paying attention to road signs and other information sources. Moreover, drivers often find themselves sidetracked from their main task of driving.
Despite the complexity and responsibilities associated with driving, where errors or risky choices can have deadly outcomes, drivers frequently partake in non-driving-related activities. There are various forms of distraction: manual distractions, like adjusting the radio; visual distractions, such as roadside advertisements; cognitive distractions, like daydreaming; and auditory distractions, like conversations with passengers.
Driver distraction is acknowledged as a contributing factor in up to 25% of all RTCs in EU nations, while 6% of all fatal RTCs in the USA are linked to distractions. Given the potential for under-reporting, these figures may underestimate the true impact of distraction. Consequently, driving distraction is an escalating concern for road safety on a global scale.
The ecological relevance of lighting research has been improved in some studies by having participants engage in a driving simulator or a driving video game while simultaneously recording target detection. In a few studies, the participants are actually behind the wheel. These investigations show that a higher S/P ratio in lighting decreases reaction times and boosts detection likelihood for peripheral targets.
However, they do not consider distractions from tasks unrelated to driving. For instance, driving on a closed road with an experimenter present means there are no other vehicles or pedestrians to navigate around, and the driver is less likely to engage in conversation with others or use their mobile phone.
Driving distractions refer to situations where drivers’ cognitive resources are inadequate for them to safely perform the driving task. An interaction between distraction and the beneficial effects of road lighting at night is anticipated. For instance, auditory distractions may lead to an increased focus on the road center, diverting attention away from peripheral hazards. Enhanced road lighting with higher luminance and S/P ratio might mitigate the negative impact of auditory distractions by improving peripheral detection.
The validity of recommendations for road lighting design, therefore, necessitates evidence regarding how these recommendations are affected by driving distractions. To achieve this, one must first understand the specific forms of distraction involved. The purpose of this review is to identify the types of distractions that occur while driving. Two data sources are utilized: interviews with drivers after collisions and observations of drivers on actual roads. The paper also assesses how the prevalence of distractions in the real world compares to drivers’ risk perceptions.
Driving a vehicle requires continuous attention. If not, accidents may occur. Unfortunately, even the most careful drivers can have crashes, often due to the actions of another driver.
In Arizona, distracted driving is one of the leading causes of motor vehicle accidents. There are four main categories of distracted driving: manual, visual, cognitive, and auditory.
1. Manual Types of Distracted Driving
Manual distractions involve anything that causes you to let go of the steering wheel. This includes reaching for, holding, or adjusting items.
Eating or Drinking
Eating and drinking can be both manual and visual distractions. You might take one hand off the wheel and divert your gaze from the road while reaching for food or a drink. Depending on your food, you may need to unwrap it or keep holding it. Your eyes can also leave the road when trying to finish your drink, and spills can lead to added distractions.
Smoking
Retrieving your cigarette from the pack and lighting it poses a manual and visual distraction. With one hand off the wheel to get your lighter and cigarettes, smoking further requires you to hold the cigarette. If hot ash falls, it can significantly increase distraction.
Applying Makeup or Grooming
How often have you seen someone doing their makeup or fixing their hair in Phoenix’s rush-hour traffic? Even if you are stopped at a light, these distractions can prevent you from noticing nearby hazards or recognizing when the light turns green. Please avoid plucking your eyebrows or shaving while driving!
Adjusting Vehicle Controls
Adjusting controls in your vehicle also counts as a manual distraction. This could involve changing the radio or temperature settings. Using your GPS while driving can be hazardous since it requires you to take a hand off the steering wheel and look away from the road.
2. Visual Types of Distracted Driving
You are visually distracted when your attention shifts away from the road ahead. This includes both internal and external distractions within or outside your vehicle. Besides the previously mentioned manual distractions, additional visual distractions can create unsafe driving conditions.
Looking at the Scenery
Given Arizona’s beautiful scenery, it’s understandable that people wish to gaze out the window while driving. Whether in heavy traffic or navigating the winding roads of South Mountain to watch the sunset from Dobbins Lookout, it’s critical to focus on the road ahead and check mirrors for vehicles behind you. On less busy streets, failing to watch the road might lead to an animal darting in front of you or your front wheels veering into the gravel.
Checking Out an Accident
When an accident occurs on the roadside, it’s natural for people to want to see what’s happening. This often leads to drivers turning their heads for a better view, which contributes to distracted driving but is easily avoidable.
Watching Pedestrians
While it’s important to be aware of pedestrians and their actions, getting too distracted by them could lead to an accident.
3. Cognitive Types of Distracted Driving
This category of distracted driving occurs when your focus is shifted away from driving. Numerous factors can draw your attention elsewhere.
Texting
Engaging in text messaging while driving is a major contributor to car accidents. Any form of electronic device use while driving can encompass manual, visual, and cognitive distractions.
Talking
When you converse on the phone or with a passenger, your focus may be diverted from the road. In 2021, Arizona enacted a law prohibiting drivers from holding their phones while talking, whether it’s propped on their shoulder or gripped in their hand. While using a hands-free device is not illegal, it remains unwise, as it can still distract you from driving.
Getting Lost in Thought
Whether you’re daydreaming or feeling upset, if your emotions are engaged in any way, your attention is not fully on driving. Operating a vehicle requires significant concentration, and if your thoughts are elsewhere, this qualifies as a form of distracted driving.
Interference in Vehicle
A passenger, a pet, children arguing, or a baby crying can all create distractions inside your vehicle. Instead of trying to manage a stressful situation while driving, it’s preferable to pull over and address the issue.
Being Under the Influence
Any factor that hampers your ability to concentrate on driving is dangerous, especially driving under the influence of drugs or alcohol. Consuming alcohol or drugs and then driving is a perilous mix. If you need to travel, find a sober driver to take you, or stay off the road. Fatigue can also lead to distraction; if you begin to feel drowsy, it’s best to pull over and rest.
4. Auditory Types of Distracted Driving
Any sound that diverts your attention from driving is classified as an auditory distraction. This includes phone calls, conversations with passengers, or the sounds of children laughing or crying. An additional common auditory distraction is listening to the radio, particularly at high volumes. If you find that you cannot hear a honking horn or an emergency vehicle siren, it’s advisable to turn down or, preferably, switch off the radio.
As the days grow shorter and we approach another winter in Kansas City, we find ourselves driving more at night. It’s unavoidable when the sun goes down by 5 PM! Unfortunately, nighttime is when driving poses the greatest risk – especially if you have any vision problems.
Did you know that depth perception, color differentiation, and even peripheral vision can be affected at night? Even worse, headlights from approaching vehicles can temporarily blind a driver. As we all understand, a traffic accident can occur in just a split second – quicker than a blink! Any vision impairment, even if fleeting, can be fatal. This is why it’s crucial to exercise extra caution when driving in the dark.
In low visibility, your reaction time decreases. Even with the brightest LED headlights, the road is only lit for 150-250 feet, which gives you less time to spot and respond to a potential hazard ahead. Mix that with high speeds and compromised vision, and it can lead to a disastrous situation.
What Causes Impaired Vision at Night?
For many, vision tends to worsen with age. Just because you might have 20/20 vision in your youth, doesn’t guarantee you’ll maintain perfect eyesight in your forties. Conditions like cataracts and various eye diseases, along with several other factors, contribute to declining eyesight as time passes. Regarding night driving, older adults generally require more light to see clearly – regardless of their overall vision quality. In simple terms, the dimmer the surroundings, the more difficult it is to see, plan, and react properly.
Additional Factors to Keep in Mind:
Despite our best efforts, we cannot always control every situation. Take rush hour, for instance. With a multitude of drivers on the road simultaneously, all eager to reach their destinations, driving can be particularly risky, especially during the winter months when it becomes dark so early.
Distracted and impaired drivers also add unpredictability. You can’t predict when another driver may unexpectedly veer into your lane or crash into the rear of your vehicle at a stoplight. Even with perfect vision, you can’t prevent others from causing chaos.
These factors contribute to the fact that 49% of traffic fatalities occur at night. Please exercise caution!
Are Night Driving Glasses Effective?
There is a widespread misconception that wearing yellow-tinted night driving glasses can enhance your visibility in the dark. The reality is that the tint seems to improve contrast, creating the illusion that the wearer can see more clearly. This is a misconception. ANY tint decreases the amount of light entering the eye, further diminishing visibility for the driver.
“Yellow ‘Night Driving’ lenses have been shown to provide no benefit in seeing ability at night. They are even dangerous because they can make a driver feel they see better, a phenomenon that is not yet explained. Research indicates that they can actually impair visual performance and delay glare recovery.” – Forensic Aspects of Vision and Highway Safety”, Merrill J. Allen, O.D., Ph.D., Et al.”
If you struggle with headlight glare or suffer from “night blindness,” it’s advisable to make an appointment with your ophthalmologist. The issue may not be the bright lights. Only through a thorough eye exam can your doctor pinpoint any medical issues or developing cataracts that may be hindering your vision.
Ways to Prevent Night Driving Accidents
Fortunately, there are several measures you can take to lessen the chances of a vision-related traffic accident.
1. Plan in advance. If possible, try to arrange your appointments and travel during daylight hours. While it’s not always feasible to adjust our schedules to fit into daylight, shifting a few tasks to daytime can significantly decrease your nighttime driving.
2. Have your eyes checked for more than just basic vision problems! A comprehensive eye exam will detect any eye diseases or conditions that may affect your night vision.
3. Ensure you’re well-rested. Fatigue can negatively impact your eyes, no matter the driving conditions.
4. Stay vigilant and limit distractions. If your attention is on your phone, it isn’t on the road ahead, which is a major concern.
5. NEVER DRIVE UNDER THE INFLUENCE OF ALCOHOL!
Regardless of your eye health or vision clarity, being cautious while driving at night is essential. Many factors beyond the condition of your eyesight influence your safety, and not all of them are within your control. Night driving is inherently hazardous, so please proceed with caution!
