The National Board of Examiners in Optometry (NBEO) administers the national board exam required to become a licensed optometrist in the U.S. The exam is delivered in parts covering applied basic science, patient assessment and management, and clinical skills, testing both foundational science knowledge and applied clinical decision-making.
The NBEO exam tests applied clinical reasoning across ocular disease, optics, and systemic health, not just isolated facts. Practising realistic multiple-choice questions with full explanations builds the clinical judgment you need, especially for the disease-diagnosis and optics-calculation questions that carry the most weight on the real exam.

Study Guide
About the real test
NBEO board exams for optometry are split into three parts: Part I ABS (Applied Basic Science), Part II PAM/TMOD (Patient Assessment and Management, including a Treatment and Management of Ocular Disease component), and Part III PEPS (Patient Encounters and Performance Skills, a hands-on clinical exam). This practice test covers the multiple-choice content tested in Parts I and II, ocular anatomy and disease, optics and refraction, systemic disease, and binocular vision.
Ocular disease and pharmacology is consistently one of the largest content areas
Recognizing disease presentations and knowing appropriate pharmacological management carries significant weight across both parts of the exam.
Optics and refraction requires calculation fluency, not just concepts
Lens power, prism calculations, and refractive error problems appear throughout. Practice the math until it's fast and automatic, not just understood in theory.
Systemic disease questions test the whole-body connection to eye health
Diabetes, hypertension, and autoimmune conditions all have recognizable ocular manifestations. Know how systemic conditions present in the eye, not just eye-specific pathology in isolation.
Why TestReadyUSA works for the NBEO Exam
TestReadyUSA's NBEO practice covers ocular anatomy, disease, optics, refraction, and systemic disease in the same proportions as the official NBEO content outlines, with a full explanation after every question.
