As we grow older, we begin to experience a decline in certain functions, including hearing vision and reaction time, and these things can begin to affect our ability to drive. Certain health conditions, including glaucoma, can speed up the process and make it unsafe for us to operate vehicles. Glaucoma affects peripheral vision and may eventually lead to blindness. While glaucoma patients retain their central vision, the peripheral field is essential to safe driving, and researchers from the Tohoku University Graduate School of Medicine in Sendai, Japan, recently examined just how much of an affect the illness can have on an individual's driving ability.

For the study, the researchers had two groups of 36 people use driving simulators. The individuals in one group had normal vision, while those in the other were diagnosed with advanced glaucoma. Glaucoma drivers were found to be twice as likely to get into collisions as the other group.

"To help ensure everyone's safety on our roadways, we would like to create mandatory vision testing guidelines for glaucoma patients," said Dr. Shiho Kunimatsu-Sanuki, lead author of the study. "We now know that integrating the visual field test into the requirements for a driver's license could save lives."

It is important for people to take their health seriously, especially when it comes to how a certain condition may affect their ability to drive. Those who do not have to give up driving and are in need of a vehicle to get around can head over to New Jersey State Auto Auction. The dealer carries a wide selection of used makes and models at affordable pricing. Plus, every car on the lot is CARFAX certified, so older drivers won't have to use all of their retirement savings to get behind the wheel of a safe and reliable vehicle.
