The program page states: "A free annual eye exam is available to all enrolled Comanche members... Exams must be 365+ days apart." For eyewear: "Enrolled Comanche members with a valid prescription receive a $250 annual allowance to purchase eyeglasses or contact lenses from our office or Modern Eyes in Lawton, OK. Assistance is limited to once per fiscal year (Oct - Sept)." The program also visits the Anadarko, Oklahoma City and Dallas outreach centers. Contact lens orders require a valid prescription and full payment at the time of order; the office notes it accepts money orders only for contact lens orders.
