I. Always bend light toward the base
II. Always bend light toward the apex
III. Cause chromatic Dispersion
IV. Move the image toward the apex
V. Are sometimes prescribed for muscle problems
I. Always bend light toward base
III. Cause chromatic dispersion.
IV. Move the image toward the apex.
V. are sometimes prescribed for muscle problems
Plus lenses are:
I. are thicker in the center than at the edges
II. Are used to correct myopia
III. Are used by all presbyopes
IV. Must be surfaced individually in the laboratory
I. Are thicker in the center than at the edges.
Which of the following does not describe a minus lens
a, The image moves with motion
b. Thicker at the edge than in the center
c. Magnifies the image
d. Corrects for myopia
c. A minus lens minifies, not maginfies
The parts of the eye that refract light are:
a. Cornea, Aqueous humor, lens and vitreous humor
b. Cornea, Iris, and lens
c.Retina, choriod, lens, and aqueous humor
d. cornea, lens, and pupil
A. Cornea, Aqueous humor, lens and vitreous humor.
Where the sclera and the cornea meet is called the
a. Iris
b. Limbus
c. Ora serrata
d. conjunctiva

, A cataract is:
a. A film over the eye
b. a cloudiness of the crystalline lens

a. Loss of accommodation.
b a shorter than normal eyeball
c. a longer than normal eyeball
d. astigmatism
C. a longer than normal eyeball
Myopia is a condition of distance vision. It is caused by the refracting system of the eye
having too much plus power for length, or the eye being too long for its power.
Eyeglasses can relieve or correct all of the following conditions except:
a. A scotoma

a. increase in accommodation
b. incipient cataract
c. ocular rejuvenation
d. surgery
b. Incipient cataract.
Some presbyopes find they no longer need glasses to read. This so called "Second
sight" is usually caused by an increase in myopia due to swelling of the crystalline lens
caused by a developing cataract.
A aphakic patient is more sensitive to light because
a. the filtering action of the crystalline lens is no longer present
b. cataract surgery often results in ptosis
