If you are a driver over the age of 50, you have an obligation to make sure that your vision is equal to the task of driving. To get a driver’s license, every state requires an eye test, most of which require a visual acuity of 20/40 or better in at least one eye and a lateral visual field width of 140-160 degrees. While this standard is reasonable, it may not go far enough. To ensure that they will drive safely, drivers should display sufficient ability to see contrasts, compensate for darkness and bright lights, see colors, and perceive depths. To assess these visual abilities, drivers are urged to undergo annual thorough eye examinations. Traffic, bad weather, and distractions can make driving challenging. Poor vision can compound these challenges and put people at risk. Older drivers should update their lens prescriptions and ask about tints and anti-reflective coatings that can improve their nighttime vision.
