COA Certified Ophthalmic Assistant Certification Exam

Certified Ophthalmic Assistant (COA) Ophthalmic practices expect assistants to grasp basic anatomy—the path light travels through cornea, lens, and retina—before stepping onto the clinic floor. The COA exam builds on that foundation, assuming you already understand intraocular pressure measurement fundamentals and can distinguish between refractive errors. Candidates lacking prior exposure to eye care terminology or optical principles face steeper learning curves during preparation.
