When driving, the need for seeing properly can not be underestimated. Actually, safety on the road relies on a number of visual capabilities such as being able to see both far ahead as well as your immediate surroundings, side or peripheral vision, seeing at night and color vision, just to name some examples.
Distance vision is vital because it lets you evaluate the road in front of you and become aware of any danger that might appear. This gives you more time to react early and avoid any accidents that might have otherwise taken place. On the other hand, if you struggle with distance vision you might not be aware of the dangers until it's too late.
Equally as important is peripheral or side vision, which allows you to see either side of your vehicle, which is needed to be aware of other cars, animals and pedestrians without needing to look away from the road ahead. Strong peripheral vision is also important for changing lanes and making turns. Make sure you know how to use both your rearview and side mirrors. Ensure they're well-positioned, to assist your view of the road to your sides and back.
Additionally, good depth perception is important for road safety. It allows you to evaluate distances properly in busy traffic, change lanes and overtake other vehicles. Accurate depth perception needs adequate sight in both eyes. In cases of people that have lost vision in one eye, it's advised to check with an optometrist to determine if it is safe for you to get behind the wheel. You may need to stop driving until a solution is found to correct your vision.
Near vision focusing or the ability to accommodate properly also comes into use on the road. This is the ability to shift your focus from a view far to something in front of you, for example, from the road to the speedometer. For those 45 or older you might have increasing difficulty with near vision, and you might need reading glasses or some other vision correction solution to help you see objects up close. Speak to your optometrist to discuss the best option.
Try not to hold off until you renew or get your driver's license to make sure your vision is in check. You don't want to endanger your own life or the lives of others on the road! If you think your eyesight isn't perfect, make an appointment with your optometrist, and get a proper eye exam sooner rather than later.
