In order to ensure the driving safety of everyone on the road, it is important to evaluate four visual factors that are critical to driving safely. The first is visual acuity, which is the ability to clearly see what lies ahead. The second is peripheral vision, the ability to see what is happening on both sides while looking straight ahead. Next is accommodation, which refers to the speed with which the eyes adjust to changes in light and dark and near and far images. Finally, there is depth perception, the ability to judge how fast cars are coming. A comprehensive eye exam checks all these crucial areas of vision, and others, to keep the roads safe for everyone. Fading night vision becomes more of a problem while driving as we get older. If you’re like most people, you rely on your car to get to work, go shopping, and bring kids where they need to go. Your ability to drive depends on your vision. Protect your vision and independence by having routine eye health examinations that include testing of visual acuity, peripheral vision, and depth perception.
