Optometry Questions with Correct Answers
Light is bent (refracted) primarily by the ______________ Correct
Answer-Cornea
Light is bent (refracted) secondarily by the _______ Correct Answer-
Lens
Light is focused onto the __________ which contains specialized neural
cells called photoreceptors to process light and change it into a chemical
signal which is transmitted through the visual pathway. Correct Answer-
Retina
Majority of the light is focused onto the ___________ -> clearest portion
of vision. Correct Answer-Macula
Chemical signal exits the eye via the ___________________. Correct
Answer-Optic Nerve (CN II)
Which lobe is involved in visual processing?? Correct Answer-The
Occipital Lobe
The ability to clearly see an image at near involves a process known as
____________________ which is controlled by CN III (Oculomotor
Nerve). Correct Answer-Accomodation
, Testing Visual Acuity: Distance _________ ft vs. Near ________ cm
Correct Answer-Distance - 20 ft
Near - 40 cm
Equipment used to cover the eye Correct Answer-Occluder
Snellen Fraction 20/20 Correct Answer-Test Distance/Letter Size:
document the smallest row of letters on the visual acuity chart where the
patient was able to correctly identify half or more of the letters
______________ condition in which the image is not clear Correct
Answer-Refractive Error
Hyperopia Correct Answer-Farsightedness (Distance can be seen
clearly, but close ones do not come into proper focus). Some people may
not notice any problems with their vision, especially when they are
young. With significant hyperopia - vision can be blurry for objects at
any distance, near or far.
Myopoia Correct Answer-Nearsightedness, Most Common refractive
error of the eye, cornea is too curved for the length of the eyeball (see
close objects clearly, but can not focus on objects further away). Light
comes to focus in front of the retina instead of on the retina.
Astigmatism Correct Answer-Irregularly shaped eyeball leading to
improper focus of objects. Does not focus light evenly onto the retina -
images appear blurry and stretched out.
