Driving with Good Vision

When on the road, the need for good vision can not be overemphasized. Actually, safety on the road requires a number of visual capabilities like distance and near vision, peripheral vision, seeing at night and color vision, plus many others.

Being able to see well into the distance is very important because it lets you scan the stretch of road ahead and become aware of any danger that might come up. Being able to see ahead gives you a chance to react early and avoid any accidents. Alternatively, if you lack strong distance vision then there's a chance you may not be aware of the hazards in time to stop an accident.

You also need peripheral vision, which allows you to see either side of your vehicle, which is crucial to see other cars, animals and pedestrians without having to look away from the road ahead. Strong peripheral vision is also crucial for switching lanes and turning. Maximize use of your side and rearview mirrors. Make sure they're well-positioned, to help your view of the road to your sides and back.

Additionally, good depth perception is important for road safety. It lets you evaluate distances accurately in dense traffic, change lanes and overtake other cars. Strong depth perception requires adequate functioning in both eyes. In cases of people that have lost vision in one eye, it's important to check with an optometrist to see whether it is okay for you to get behind the wheel. It may be suggested that you stop driving until your vision is corrected to achieve proper depth perception.

Accommodation also plays an important role when driving. This is the capability to shift your focus from a view far to something close, such as from the distance ahead of you to the speedometer. For those 45 or older you may have increasing difficulty with near vision, and you might need glasses or another corrective device to help you see objects up close. Make an appointment with your optometrist to discuss the best option.

Being able to see color is also pretty important on the road. Drivers must be able to immediately identify traffic lights, indicator signs and warning signals. If you've got a color vision defect, response time may be slower than normal. If this is the case, it's best not to wear medium or dark colored sunglasses, because these can seriously interfere with your ability to identify colors.

At the first sign of vision problems, think about how it affects your ability to drive. You don't want to risk your life or those of other people on the road! If you feel your vision isn't perfect, visit your optometrist, and have a proper eye exam sooner rather than later.
