![]() ![]() ![]() If visual field is less than 140º but better than 110º using both eyes or better than 100º using 1 eye, then outside mirrors are required on both sides of vehicle. If BCVA is between 20/70 and 20/40 using both eyes, then the driver passes with daylight driving restriction. Outside mirrors and daylight driving only if BCVA is 20/50 in one eye and less than 20/70 in the other eye or if BCVA is at least 20/70 in each eye. Outside mirrors are required if BCVA in one eye is at least 20/40 and BCVA in the other eye is less than 20/50. Night driving can be requested after 1 year of accident-free driving with telescopes. īioptic telescopes are allowed if BCVA with telescopes is 20/40-telescopic licenses allow daylight driving only for the first year. Outside mirrors required on both sides of vehicle if BCVA is 20/40 in only one eye, daylight driving only if BCVA is 20/41 to 20/70 in both eyes, Outside mirrors required on both sides of vehicle AND daylight driving only if BCVA is 20/41 to 20/70 in only one eye. ![]() ġ40º using both eyes, outside mirrors required on both sides of the vehicle if one eye has 70º temporally and 35º nasally Īn ability to differentiate traffic colors and signals is required. ġ30º of uninterrupted horizontal field using both eyes ĭriver may pass with restrictions if BCVA is 20/70 in one eye only if the other eye is at least 20/200.

Non-Commercial Driving Requirements per StateĪbsolute Low Vision BCVA Cut Off (Snellen) Consequently, there will be a greater need for low vision information and services in the U.S. affected by low vision is expected to rise over the next 30 years for all ethnicities. Black and Hispanic populations have a higher prevalence of low vision than White populations, and this difference becomes more pronounced after the age of 80. Prevalence of low vision increases with age, according to 2010 U.S. EpidemiologyĬourtesy: National Eye Institute, National Institutes of Health (NEI/NIH) However, there is greater variation with visual field requirements, and some states do not require any visual field testing for licensure. ![]() Each state requires visual acuity measurements for licensure, and almost all set the minimum BCVA requirement to 20/40. Diagnosis of low vision is established by visual acuity examinations using the LogMAR chart, which is preferred over the Snellen chart due to improved accuracy. There are many causes of low vision, including macular degeneration, glaucoma, diabetic retinopathy, retinitis pigmentosa, eye trauma, and brain injury. In contrast, the World Health Organization defines low vision as BCVA of 20/60 to 20/200 or visual field <20 degrees in the better seeing eye.
