When driving, the need for seeing properly can not be underestimated. If you think about it, driving safely needs a combination of a number of different visual capabilities including the ability to see both near and far ahead, peripheral vision, seeing at night and color vision, plus many others.
Being able to see well into the distance is highly necessary because of how it lets you observe the road in front and become aware of any dangers that might be present. Being able to see ahead gives you more time to act fast and avoid any accidents that might have otherwise taken place. Alternatively, if you lack strong distance vision then there's a chance you may not be able to see dangers in time to stop an accident.
Just as important is peripheral or side vision, which enables you to see to the sides of your car, which is crucial to spot other cars, animals and pedestrians without having to look away from the road lying ahead. Being able to see peripherally is also crucial for changing lanes and making turns. Use your side and rearview mirrors. Ensure they're adjusted correctly, to help your view of the road to your sides and back.
Additionally, good depth perception is important for road safety. This allows you to measure distances correctly in crowded traffic, switch lanes and overtake other vehicles. Accurate depth perception calls for adequate sight in both eyes. If one lacks proper vision in one eye, it's advised to check with an eye doctor to determine if it is okay for you to get behind the wheel. You may have to refrain from driving until your vision is corrected to achieve proper depth perception.
Near vision focusing or the ability to accommodate instantly also comes into use when driving. If you're unfamiliar with the term accommodating, it is the capability to move your focus from something in the distance to something near, like from the road to the speedometer. For those 45 or older you might have a slight challenge with near vision, and you might need reading glasses or another corrective device to help you see objects up close. Make an appointment with your optometrist to discuss the options.
At the first sign of a vision problem, think about how it affects your ability to drive. You don't want to endanger your own life or the lives of other people on the road! If you feel your vision isn't adequate, make an appointment with your eye doctor, and get a proper eye exam sooner rather than later.
