When on the road, the need for seeing properly can not be underestimated. If you think about it, driving safely depends on a combination of a number of different visual capabilities such as being able to see both far ahead as well as your immediate surroundings, side or peripheral vision, seeing in limited light and color vision, just to name some examples.
Being able to see well into the distance is very important because it lets you observe the road in front and see any danger that might appear. Most importantly, it gives you more time to react early and stop any accidents. And on the flip-side, if you struggle with distance vision then there's a chance you may not be able to see dangers in time to stop an accident.
Distance vision is also affected by the state of your glasses and windshield, so make sure both are kept clean and clear of both dust and scratches which can inhibit your ability to see clearly, mostly at night and on bright days.
You also need peripheral vision, which enables you to see the sides of your car, which is crucial to see pedestrians, animals and cross traffic without needing to even glance away from the road ahead. Strong peripheral vision is also crucial when switching lanes and making turns. Maximize use of your side and rearview mirrors. Ensure they're adjusted correctly, to enhance your view of the road to your sides and back.
Additionally, good depth perception is important for road safety. It helps you evaluate distances correctly in busy driving conditions, switch lanes and overtake other vehicles. Strong depth perception needs adequate functioning in both eyes. If you've lost visual acuity in one eye, it's advised to consult with an optometrist to determine whether it is safe for you to drive. It may be suggested that you stop driving until a solution is found to correct your vision.
Accommodation also comes into use while on the road. Accommodating is the ability to shift your focus from something ahead to something near, like from the distance ahead of you to the speedometer. If you've recently hit middle-age you may have increasing difficulty with near vision, and it's normal to require glasses or some other vision correction solution to make it easier to see objects up close. Speak to your eye doctor to discuss the best option.
Being able to see color is also pretty important in the car. Those driving need to be able to quickly recognize traffic lights, road signs and warning signals. For those with color blindness, your response time could be a little slower than that of others. If this is the case, avoid using medium or dark blue sunglasses, because these can seriously interfere with your ability to discern colors.
At the first sign of vision problems, think about how it affects your ability to drive. You can't afford to risk your own life or those of the others on the road! If you think your vision isn't perfect, visit your eye doctor, and get a proper eye exam right away.
