A driver’s eyesight is critical in preventing car crashes, because nearly all the sensory input you need to drive a car comes from visual cues. If your eyesight is diminished, so is your ability to drive safely. This is especially important to senior drivers.
That’s why most states require motorists to undergo vision tests as part of the driver’s license renewal process. Depending on where you live, you may have a vision test in person at a state licensing office or submit results of a vision test performed by an eye doctor.
