Excellent eyesight is essential for road safety. Actually, safe driving relies on a combination of a number of different visual abilities - for example, the ability to see both near and far ahead, side or peripheral vision, seeing in limited light and color vision, to name a few.
Being able to see well into the distance is very important because it helps you to scan the road ahead and see any dangers that might appear. This gives you the opportunity to respond quickly and prevent any mishaps that could take place. Alternatively, if you struggle with distance vision you might not be able to see the dangers soon enough.
Distance vision is also influenced by the maintenance of your glasses and windshield, so check that they are kept really clean and scratch-free which can inhibit your ability to see clearly, mostly at night and on bright days.
Just as important is peripheral vision, which allows you see to the sides of your vehicle, which is important to spot other cars, animals and pedestrians without needing to even glance away from the road lying ahead. Being able to see peripherally is also crucial when you're changing lanes and making turns. Maximize use of both your rearview and side mirrors. Make sure they're adjusted correctly, to assist your view of the road to your sides and back.
Additionally, good depth perception is important for road safety. This lets you evaluate distances correctly in busy traffic, change lanes and pass other vehicles. Strong depth perception calls for adequate sight in both eyes. If you've lost visual acuity in one eye, it's advised to check with your eye doctor to determine if it is okay for you to get behind the wheel. You may need to refrain from driving until your vision is corrected to achieve proper depth perception.
Accommodation also comes into use while on the road. This is the capability to move your focus from a view far to something in front of you, like from the road to the dashboard. If you're over the age of 45 you might have increasing difficulty with near vision, and you might need glasses or another corrective device to help you see objects up close. Call your eye doctor to talk about the options.
Try not to hold off until you renew or apply for your driver's license to get your eyes checked. You don't want to risk your own life or the lives of other people on the road! If you feel your eyesight isn't adequate, visit your eye doctor, and get a proper eye exam right away.
