Optical Equipment Training
Master the essential instruments every optician must know. These skills are critical for the ABO/NCLE exams and daily practice.
ABO Exam Alert
The ABO certification exam includes a practical component where you must demonstrate proficiency with optical equipment. The computerized exam simulates real equipment that you must operate correctly. Understanding how these instruments work is essential for passing.
- Lensometer: You'll neutralize lenses and identify prescription values
- Keratometer: You'll measure corneal curvature and identify K-readings
- Slit Lamp: NCLE exam includes biomicroscopy evaluation

Tips for Equipment Mastery
Learn the Theory First
Understand the optical principles behind each instrument before practicing. Know why you're doing each step.
Practice Systematically
Develop a consistent routine for each instrument. Same steps, same order, every time. This builds speed and accuracy.
Verify Your Work
Always double-check measurements. Re-neutralize lenses, re-read K-values. Accuracy is more important than speed.
