You are required to pass a vision test when you apply for your drivers license. It is important to have your eyes checked every year or two. You may not know that you have poor peripheral vision or poor distance judgment unless your eyes are checked. Wear your glasses or corrective contact lenses if you are required to do so.
Good vision is essential for driving. Most of what you do behind the wheel is based on what you see. You need to be able to see "out of the corner of your eye." This lets you spot cars approaching on either side of you while watching the road ahead.
It is important to know that many who are able to see clearly during the day have trouble seeing clearly at night; some see poorly in dim light and others may have trouble seeing around the glare of headlights.
