Prepare for NCLE Exam
The National Contact Lens Examiners (NCLE) exam proves your competency in fitting and dispensing contact lenses.
Why Take the NCLE?
While some states only require the ABO, having both certifications makes you a "Dual-Certified" Optician. This significantly increases your employability and salary potential.
Salary Boost
Dual-certified opticians typically earn 15-25% more than those with only one certification.
NCLE Prep with Opterio
Don't walk in unprepared. Opterio's NCLE prep includes thousands of practice questions on contact lens parameters, material science, and patient education.

The Evolution of Contact Lens Tech
Contact lenses are one of the most technologically advanced areas of eye care. As a certified NCLE professional, you must stay current with the latest developments in material science—from the early days of PMMA to the highly breathable silicone hydrogels of today. Understanding the Dk/t (oxygen transmissibility) of different materials is crucial for ensuring the long-term corneal health of your patients.
The NCLE exam will test your ability to translate a spectacle prescription into a contact lens prescription, accounting for vertex distance changes and corneal curvature (base curve). This level of specialized knowledge makes you an invaluable asset to any optometric or ophthalmological practice.
Clinical Competency
Mastering these four areas is key to passing the NCLE and succeeding in practice:
Patient Instruction: Teaching a first-time wearer how to safely insert and remove their lenses.
Slit Lamp Basics: Evaluating the fit, movement, and centration of a lens on the eye.
Follow-Up Care: Identifying signs of overwear or material sensitivity before they become serious issues.
Keratometry: Using precise measurements of corneal curvature to select the ideal base curve.
Becoming a Dual-Certified Expert
Holding both ABO and NCLE certifications is the hallmark of a true optical professional. It shows your dedication to mastering all aspects of vision correction. In many states, this "Dual-Certified" status is required for higher-level management positions and can serve as a powerful bargaining chip during salary negotiations.
Key NCLE Topics
Fitting & Assessment
Slit lamp evaluation, keratometry, and assessing fit on the eye.
Ocular Anatomy
Deep dive into the cornea, tear film, and contact lens interactions.
Material Science
Dk values, water content, and material types (SCL, RGP, Scleral).
Patient Education
Insertion, removal, and proper lens care protocols.
