Visual acuity must be measured with both eyes open while wearing any corrective lenses usually worn for driving.
Eye sight requirements:
Not less than 20/40 with both eyes open and examined together. |
The minimum field of vision for safe driving is defined as a field of at least 120degrees on the horizontal plane.
Note: Visual field assessment using the automated vision testers typical at Department of Motor Vehicles may be insensitive to some visual field defects. |
Typically should not drive, however, should be assessed by the driver licensing authority on an individual basis. An ophthalmologist’s report should be submitted to the driver licensing authority, which may then consider a conditional license. |
No restrictions for monocular drivers if standards for visual acuity and field of vision are met. |
May drive if meets the acuity criteria. Specialist opinion recommended. |
With contact lens or intraocular lens following cataract removal: May, after full recovery, qualify for a license if able to wear contact lenses or have had an intraocular lens transplant. The surgeon should advise the patient when it is safe to resume driving. |
May drive if an optometrist’s or ophthalmologist’s report is obtained stating that the visual acuity and visual field criteria are met. Must be subject to annual evaluation of vision and visual fields by an eye care specialist, with the report forwarded to the licensing agency. |
No restrictions for deficits in color vision if standards for visual acuity and field of vision are met. |
Should not drive at night or under other low light daytime conditions. |
Physician should advise re: driving if condition is severe enough to interfere with eye comfort or vision. |
Should not drive in the early stages of diplopia. If the diplopia can be completely corrected with a patch or prisms to meet the standards for visual acuity and visual field, the driver may be eligible to drive on specialist recommendation. |
No restrictions if standards for visual acuity and field of vision are met. |
Individuals with fixed ptosis can drive provided lids do not obscure the pupil of both eyes and the applicants are able to meet the standards for visual acuity and field without having to hold their head in an extreme position. |
The ability to drive safely using bioptic lenses should be demonstrated by a road test. |
