Missouri Bioptic Laws
 

Bioptic telescopes are permitted, but not for the vision test. They can be used during the road test.

  • Visual Acuity: The vision standard is 20/40 acuity or better, with or without correction, with either eye or both eyes, and temporal horizontal peripheral vision in each eye of 55 degrees or better.
  • If the applicant does not have at least 20/40 acuity or has less than 55 degrees temporal horizontal peripheral vision in one eye and less than 85 degrees temporal horizontal peripheral vision in the other eye, he or she is referred to a vision specialist to have a complete vision exam conducted, and is required to bring the results back to the licensing office.
  • Applicants with acuity between 20/41 and 20/59 with either eye or both eyes are restricted to corrective lenses and daylight driving only.
  •  Applicants with acuity between 20/60 and 20/74 with either eye or both eyes with corrective lenses are subject to a corrective lens restriction as well as daylight driving only and maximum speed of 45 mi/h restrictions. Restrictions may also include points of operation, times of operation, or any other driving conditions deemed necessary.
  • For an applicant who has an acuity reading between 20/75 and 20/160, a Driver Condition Report will be completed by the Licensing Employee, and the applicant would be directly referred to the Highway Patrol Examiners to complete the required skills test.
  • Applicants with vision of 20/161 or less are denied a MO driver's license, as are applicants with a combined horizontal peripheral vision reading of less than 70. Unrestricted: 20/40 in the better eye, with or without corrective lenses. Restricted: up to 20/160 in the better eye.
  • Visual Field: 55 degrees or better in both eyes. 85 degrees in one eye: restrictions apply.
