Excellent vision is essential for road safety. As a matter of fact, driving safely relies on a number of visual capabilities such as being able to see both far ahead as well as your immediate surroundings, peripheral vision, seeing at night and color vision, plus many others.
Distance vision is very important because of how it helps you to evaluate the stretch of road ahead of you and become aware of any dangers that might be present. This gives you a chance to act fast and avoid any mishaps that could take place. Alternatively, if you lack strong distance vision then there's a chance you might not be able to see the dangers until it's too late.
Distance vision is also influenced by the maintenance of your windshield and glasses (including sunglasses), so make sure these are clean and free of both scratches and dust which can reduce your vision, especially when it's dark or sunny.
Just as important is peripheral vision, which allows you see to the sides of your car, which is crucial to spot pedestrians, animals and cross traffic without needing to look away from the road ahead. Being able to see peripherally is also crucial for switching lanes and turning. Maximize use of both your rearview and side mirrors. Ensure they're adjusted correctly, to enhance your side vision.
Road safety is also highly dependent on good depth perception. It lets you evaluate distances correctly in crowded traffic, switch lanes and overtake other vehicles. Strong depth perception needs adequate vision in both of your eyes. If one lacks proper vision in one eye, it's essential to check with an eye doctor to see whether it is safe for you to get behind the wheel. It may be suggested that you stop driving until your vision is corrected to achieve proper depth perception.
Near vision focusing or being able to accommodate instantly also comes into use when driving. If you're unfamiliar with the term accommodating, it is the ability to shift your focus from something far to something in front of you, like from the distance ahead of you to the dashboard. For those 45 or older you might have increasing difficulty with near vision, and it might be helpful for you to get reading glasses or some other corrective device to help you see your dashboard. Call your optometrist to discuss the best option.
Don't wait until you renew or get your driver's license to make sure your vision is in check. You don't want to risk your life or the lives of others on the road! If you think your eyesight isn't perfect, make an appointment with your eye doctor, and get a thorough eye exam right away.
