In this study, researchers will review the current visual requirements for CMV drivers, concentrating on the requirements for visual acuity and visual fields, and consider the limitations. Additionally, researchers will assess the proportion of people, particularly the population of aging CMV drivers, who fail to meet the current visual requirements. The current standard requires drivers to have:
� A distant visual acuity of at least 20/40 (Snellen) in each eye without corrective lenses or visual acuity separately corrected to 20/40 (Snellen) or better with corrective lenses;
� A distant binocular acuity of at least 20/40 (Snellen) in both eyes with or without corrective lenses;
� A field of vision of at least 70 degrees in the horizontal Meridian in each eye;
� The ability to recognize the colors of traffic signals and devices showing standard red, green, and amber. |
