These are therapists who are certified by the Academy for Certification of Vision Rehabilitation and Education Professionals (ACVREP). A vision rehabilitation therapist, an O&M, a teacher of the visually impaired, an occupational therapist, a physical therapist, and a nurse are all qualified to take the national certification examination administered by ACVREP to become a certified low vision therapist (CLVT). An occupational therapist who are certified in low vision is the only profession that is eligible to practice independently and be reimbursed by Medicare.
