Improving eyesight for driving in the dark
Post on 10th September 2024
As the days get shorter, many of us find ourselves experiencing higher anxiety as we spend more time driving in the dark. Whether it’s the evening commute or a nighttime road trip, driving in the winter months can present some unique challenges – and risks – when it comes to our vision and safety.
While many drivers take precautions by equipping their vehicles with de-icer and an ice scraper, one important aspect often overlooked is the impact of winter weather on eyesight.
At Scrivens Opticians & Hearing Care, we have over 85 years of experience helping people care for their eye health, and we offer a range of drive safety lenses.
Maintaining good eyesight during winter driving is critical for your personal safety and the safety of others. Here we provide tips on how to protect and enhance your vision for safer winter driving.
How Vision Changes in the Dark
When we move from bright daylight to darkness, our eyes have to adjust. The pupils dilate to let in more light, and our retinas switch from relying primarily on cone cells (which detect colour) to rod cells (which are better at detecting contrast and movement in low light).
This adjustment period, known as dark adaptation, can take 30 minutes or more. During this time, our peripheral vision, depth perception, and ability to discern colours and details all diminish. Glare from oncoming headlights or streetlights can also be more problematic.
Tips for Safer Nighttime Driving
Fortunately, there are some steps you can take to help compensate for these vision challenges and stay safer on the road after dark:
- Get your eyes checked regularly. Schedule regular eye tests to ensure your eyesight is ‘winter’ ready and in good condition.
- Drive-safe Eyewear: If you require corrective lenses, make sure your glasses or contact lenses are up to date and provide clear vision. At Scrivens, we recommend anti-reflective coatings to reduce glare and have a range of drive-safe lenses for you to choose from.
- Optimise your headlights. Ensure your headlights are properly aimed and clean.
- Reduce dashboard glare. Use the dimmer switch on your dashboard to minimise reflections that can impair your vision.
- Avoid looking directly at oncoming headlights. If possible, glance slightly to the right of oncoming traffic to reduce glare.
- Give your eyes time to adjust. When entering a dark area, look slightly to the side rather than straight ahead to help your eyes adapt more quickly.
- Keep your windscreen clean. Streaks and smudges can scatter light and reduce visibility.
- Slow down. Driving at a slower, safer speed gives you more time to react to hazards you might not see as clearly.
Prioritising your eyesight can greatly improve your safety on the road during the shorter daylight months. If you have any concerns about your eye health, you will find help and advice on our website or alternatively visit your local Scrivens branch.
