Visual Acuity Research Paper

Visual acuity: For private drivers, corrected vision less than 20/50 (6/15) with both eyes open and examined together; for commercial drivers, refer to visual acuity standards.
Visual field: For private drivers, field less than 120°† along the horizontal meridian and 15° continuous above and below fixation, with both eyes open and examined together; for commercial drivers, refer to visual field standards.
Diplopia within the central 40° of the visual field (i.e., 20° to the left, right, above and below fixation).
Recent functional change from binocular to monocular vision, including temporary patching of an eye. (Page 48 CMA 8)

In these circumstances, functional assessments are indicated. (Page 48 CMA
