Daylight only driving – Best eye corrected visual acuity of 20/50 to 20/100. Correctable diplopia may also require a license restriction. A vision test is required prior to taking your driver's license examination.

The numbers in your visual acuity measurement have to do with distance. It might be easiest to explain if you imagine the Snellen chart: When you have a Snellen test score of 20/40, that means you'd see the chart as clearly at 20 feet away as someone with “normal” vision would see it from 40 feet away.

Based on visual acuity testing, a person is considered legally blind when their best corrected vision is 20/200, which means they need to be at least 20 feet away to see something that a person with normal vision can see from 200 feet away.

The applicant shall have a visual acuity of at least 20/200 in both eyes with the best conventional non- telescopic corrective lens(es), and a full visual field. The central field vision loss shall not exceed five (5) degrees. The applicant's visual acuity with the bioptic telescope shall be at least 20/60.

A Snellen eye chart is a common component of vision exams for the DMV.

To obtain or to renew a permit or license, applicants must take and pass a vision screening test. Drivers who cannot meet the 20/40 acuity standard are referred to an eye-care specialist. Drivers whose vision is correctable to 20/50 or better are restricted to wearing corrective lenses when driving.

If your vision is 20/60, this means that from 20 feet away you can only see letters that would normally be visible at 60 feet.

The simple eye test given by the SCDMV determines if you have 20/40 vision or better. If you are unable to pass the SCDMV vision screening at a branch office, you must have your eyes examined by a licensed eye care professional to determine if your eyes meet South Carolina's vision requirements.
