To screen your vision, a DMV staff member will ask you to look into a machine and read a series of letters or numbers. The vision screening is not a medical exam. The screening shows whether your vision meets Virginia’s standards to safely drive. If you fail the vision screening, you may be asked to visit an eye care professional. If you need to wear glasses or contact lenses to pass the visions screening, you must wear them when you drive. Your license will display a C for this restriction. To have this restriction removed after having laser surgery to correct your vision, you must visit a DMV customer service center and pass the vision screening without wearing glasses or contact lenses or submit a Vision Screening Report (MED 4).
