Core Domains:
1. Advanced Preliminary Testing and Diagnostic Procedures (25 questions)
2. Instruments and Advanced Equipment Maintenance (25 questions)
3. Patient History, Communication, and Clinical Workflow (25 questions)
4. Ocular Anatomy, Physiology, and Common Pathologies (25 questions)
Introduction
This comprehensive examination is designed to assess the knowledge and
clinical competency required for the National Vision Optometric Technician
Level 2 certification. It evaluates the candidate's understanding of advanced
preliminary testing and diagnostic procedures, instrument operation and
maintenance, patient communication and clinical workflow, and ocular
anatomy, physiology, and common pathologies. The exam utilizes a multiple-
choice format with scenario-based questions that reflect real-world clinical
situations encountered by optometric technicians. Emphasis is placed on the
application of clinical reasoning, proper use of diagnostic equipment, patient
interaction skills, and the ability to identify and manage common ocular
conditions. This assessment serves as a predictor of success on the official
National Vision Level 2 certification examination and helps identify areas for
,focused review. The content is organized into four balanced domains aligned
with the National Vision Optometric Technician Level 2 blueprint.
SECTION ONE: QUESTIONS 1 - 100
DOMAIN 1: ADVANCED PRELIMINARY TESTING AND DIAGNOSTIC
PROCEDURES (Questions 1–25)
1. The Jackson cross cylinder is used during subjective refraction to:
A. Refine the axis and power of the cylinder correction
B. Measure intraocular pressure
C. Assess the macula
D. Evaluate tear production
A. Refine the axis and power of the cylinder correction
RATIONALE: The Jackson cross cylinder compares the visual clarity of
two optical prescriptions to judge the axis and power of cylinder correction. It
is a critical tool during subjective refraction for fine-tuning astigmatic
correction.
2. The duochrome (red-green) balance procedure is used to:
A. Verify the spherical endpoint using chromatic aberration
B. Assess for color vision deficiency
C. Measure corneal curvature
D. Evaluate the peripheral field
A. Verify the spherical endpoint using chromatic aberration
RATIONALE: The duochrome procedure uses the eye's chromatic
aberration, focusing slightly in front of and behind the retina, helping
confirm the spherical endpoint. Red focuses behind the retina, green in front,
requiring the patient to choose the clearer target.
3. The Worth 4-dot procedure evaluates:
A. Visual acuity
,B. Intraocular pressure
C. Binocular fusion and suppression
D. Contrast sensitivity
C. Binocular fusion and suppression
RATIONALE: The Worth 4-dot display, viewed with red-green lenses,
reveals whether both eyes are fusing, suppressing, or experiencing diplopia. It
is essential for assessing binocular vision status.
4. The Maddox rod is used to measure:
A. Intraocular pressure
B. Corneal thickness
C. Central visual acuity
D. Heterophoria, or a latent eye deviation
D. Heterophoria, or a latent eye deviation
RATIONALE: The Maddox rod dissociates the two eyes by turning a point
of light into a streak, allowing measurement of latent misalignment (phoria).
It is used with a light source to quantify horizontal and vertical deviations.
5. An alternating prism cover procedure quantifies:
A. Refractive error in diopters
B. Corneal power
C. The magnitude of a strabismus deviation in prism diopters
D. Pupil diameter
C. The magnitude of a strabismus deviation in prism diopters
RATIONALE: The alternating prism cover test is used to measure the total
deviation in strabismus by neutralizing the eye movement with prisms,
quantifying the magnitude in prism diopters.
6. Confrontation visual field testing is primarily used to:
A. Measure central visual acuity
B. Detect peripheral field defects
, C. Evaluate color vision
D. Measure intraocular pressure
B. Detect peripheral field defects
RATIONALE: Confrontation visual field testing is a quick screening
method to detect peripheral field defects, comparing the patient's field to the
examiner's. It is useful for detecting gross defects.
7. What additional procedure should be recommended in the pre-test
room if a patient informs you that they have a family history of
glaucoma?
A. Visual Fields Test
B. Ishihara test
C. LASIK
D. Cataract surgery
A. Visual Fields Test
RATIONALE: Visual field testing is essential for glaucoma screening, as it
detects peripheral vision loss characteristic of the disease. Family history of
glaucoma is a significant risk factor requiring this diagnostic procedure.
8. The Amsler grid is used to evaluate which area of vision?
A. Peripheral vision
B. Central vision (macula)
C. Color vision
D. Depth perception
B. Central vision (macula)
RATIONALE: The Amsler grid is a screening tool for macular function,
detecting central visual field defects associated with macular degeneration
and other retinal conditions.
9. Which retinal cells are responsible for color vision, daytime vision,
and the central portion of the visual field?
