(3) If an applicant has less than fifty-five degree (55°) temporal horizontal peripheral vision in one (1) eye and at least eighty-five degree (85°) temporal horizontal peripheral vision in the other eye, they shall receive a license with the following restriction:

(B) Restricted to forty-five miles per hour (45 mph).

1. At the discretion of the department, either of the two (2) restrictions listed in subsections (4)(A) and (B) may be removed or waived from the driver license if an eye doctor or physician recommends removal.
