Department of Motor Vehicle laws in every state require that you pass a vision test to get or renew a driver’s license. While state laws may vary slightly, they typically call for visual acuity of at least 20/40 in either or both eyes, with or without corrective eyeglasses, and peripheral vision of 140 degrees.

Understand Vision Test Requirements

Driver’s license vision screening focuses on visual acuity, peripheral vision and in some states, the ability to see colors. Check the laws in your state, as colorblindness may result in an automatic failure in some states. Examiners use a [Snellen eye chart](http://www.visionsource.com/doctors/free-eye-chart-download/?it=patients/free-eye-chart-download/) to measure visual acuity — distance vision — and a computerized machine to test peripheral vision. If you normally wear corrective lenses, bring them with you, as you must wear them during the exam.
