Proper vision is required for safe driving. If you think about it, staying safe on the road requires several different visual capabilities like being able to see both far ahead as well as your immediate surroundings, peripheral vision, seeing at night and color vision, just to name a few.
Strong distance vision is highly necessary because it allows you to evaluate the road in front and become aware of any dangerous things that might come up. Most importantly, it allows you to act fast and stop any mishaps that could take place. And on the flip-side, if you struggle with distance vision then there's a chance you might not be aware of hazards until it's too late.
Distance vision is also influenced by the maintenance of your glasses and windshield, so make sure they are clean and scratch-free which can inhibit your sight, especially when it's dark or sunny.
You also need peripheral or side vision, which enables you see both sides of your car, which is needed to be aware of pedestrians, animals and cross traffic without needing to look away from the road ahead. Strong peripheral vision is also crucial for changing lanes and turning. Use your side and rearview mirrors. Check they're angled properly, to help your side vision.
Additionally, good depth perception is important for road safety. It lets you measure distances properly in busy traffic, change lanes and pass other cars on the road. Accurate depth perception calls for proper vision in both of your eyes. If you've lost visual acuity in one eye, it's essential to consult with an eye doctor to determine whether it is okay for you to get behind the wheel. You may have to stop driving until a solution is found to correct your vision.
Near vision focusing or being able to accommodate effectively also plays an important role while on the road. Accommodating is the ability to shift your focus from something ahead to something in front of you, like from the road to the dashboard. For those 45 or older it's common for you to have trouble with near vision, and you might need glasses or another corrective device to make it easier to see objects up close. Make an appointment with your optometrist to talk about the best option.
Try not to hold off until you renew or get your driver's license to get your eyes checked. You don't want to endanger your life or those of other people on the road! If you feel your vision isn't perfect, see your eye doctor, and have a proper eye exam sooner rather than later.
