ABO (AMERICAN BOARD OF OPTICIANRY) EXAM
Exam Coverage
Exam coverage for the ABO (American Board of Opticianry) Exam
includes the core optical dispensing knowledge and practical
principles required for optician certification. It focuses on ophthalmic
lens types, prescription interpretation, frame and lens selection,
measurements, lens materials, multifocal designs, and optical theory.
The exam also evaluates understanding of spectacle fabrication,
fitting, adjustments, repairs, eye anatomy relevant to dispensing,
patient communication, and professional standards. Emphasis is
placed on applying optical calculations accurately, ensuring proper
eyewear performance and fit, and delivering safe, effective optical
care in professional practice.
,The extra-ocular muscles are inserted into the sclera and serve to
rotate the eye in all possible directions. There are _______of these
muscles.
Six
The fibrous tunic is comprised of the:
Sclera and cornea
Fusion occurs:
In the brain
,The aqueous fluid is continually being manufactured by:
The ciliary body
The ability of the eye to bring objects of varying distances to focus on
the retina is known as:
Accommodation
When accommodation is at rest, rays of light from a distant source
come to focus behind the retina. This condition is known as:
Hyperopia
, Impulses are carried from the retina to the brain along the:
Optic nerve
That area of the retina capable of perceiving the greatest amount of
detail is:
Fovea centralis
The average cornea has a refractive power of approximately:
43 diopters
