NAO Exam Review Book Questions And Answers
1. 1 m = 10 dm = 100 cm = 1000 mm: Formula of Metric System:
2. There are one billion nanometers in a meter: How many
nanometers are there in a meter?
Longer than visible red light waves: The wavelengths of the infrared
3.
waves in the electromagnetic spectrum are:
4. 1.530: The geneva lens measure is calibrated for a refractive index of:
5. Has against motion: A lens made from 2 convex surfaces:
6. +8.25D: Using the corrected curve theory, a lens reads +4.25D in the vertometer. If
the ocular curve is -4.00D, what is the front base curve?
7. +3.00: Which of these front base curves would be suitable for a -3.00D meniscus
lens?
8.Appropriate chemicals added during manufacturing and its
density: A tinted lens will absorb visible light, infrared and ultraviolet because
of:
9. Superior Rectus: Moves the eye up
10. Superior oblique: Rotates the eye so that the top of the eye moves toward the
nose
11. Medial Rectus: Moves eye toward the nose

, 12. Lateral Rectus: Moves eye away from the nose
13. Inferior Rectus: Moves the eye down
14. Inferior Oblique: Rotates the eye so that the top of the eye moves away from
the nose
15. The Annulus of Zinn: The four rectus muscles arise from a fibrous ring at the
back of the orbit called
16. Abduction: The ability of the eye to turn out is called:
17. Adduction: The ability of the eye to turn in is called:
18.Phoria, tropia: A refers to the potential (or tendency) for an eye to turn
or deviate. If the eye actually deviates, it is called a
19. Esophoria: If the occluded eye turns in
20. Exophoria: If the occluded eye turns out
21. Hypophoria: If the occluded eye turns downward
22. Orthophoria (eyes that are correctly carried): If the occluded eye
does not turn or deviate
23.Amblyopia: Also called "lazy eye" is decreased vision in the deviating eye due
either to strabismus or an uncorrected refractive error.
