1. Which part of the eye is primarily responsible for focusing light
onto the retina?
A. Cornea
B. Lens
C. Iris
D. Retina
B. Lens
The lens adjusts its shape to focus light onto the retina, allowing
for clear vision at different distances.
2. A patient presents with blurred vision and difficulty seeing objects
up close. This condition is most consistent with:
A. Myopia
B. Hyperopia
C. Astigmatism
D. Presbyopia
B. Hyperopia
Hyperopia is farsightedness, where close objects appear blurry
because the focal point is behind the retina.
3. Which instrument is used to measure the curvature of the cornea?
A. Phoropter
B. Keratometer
C. Retinoscope
D. Slit lamp
, B. Keratometer
A keratometer measures the corneal curvature to help fit contact
lenses or assess corneal abnormalities.
4. The unit of measurement for lens power is:
A. Diopter
B. Millimeter
C. Centimeter
D. Micron
A. Diopter
Lens power is expressed in diopters, indicating the lens’s ability to
converge or diverge light.
5. Which of the following is a contraindication for contact lens wear?
A. Myopia
B. Keratoconjunctivitis sicca (dry eye)
C. Astigmatism
D. Hyperopia
B. Keratoconjunctivitis sicca (dry eye)
Severe dry eye can prevent proper lens fitting and may cause
discomfort or corneal damage.
6. In which part of the eye are rods and cones located?
A. Cornea
B. Retina
C. Lens
D. Iris
B. Retina
The retina contains photoreceptor cells—rods for low-light vision
and cones for color and detail.
,7. Which lens type is used to correct myopia?
A. Convex (plus) lens
B. Concave (minus) lens
C. Cylindrical lens
D. Bifocal lens
B. Concave (minus) lens
Concave lenses diverge light, moving the focal point backward to
correct nearsightedness.
8. What is the main function of the iris?
A. Focus light
B. Control the size of the pupil
C. Protect the retina from UV light
D. Produce aqueous humor
B. Control the size of the pupil
The iris adjusts pupil size, regulating the amount of light entering
the eye.
9. The visual acuity 20/40 means:
A. The patient sees at 20 feet what a normal person sees at 40
feet
B. The patient sees at 40 feet what a normal person sees at 20
feet
C. The patient has normal vision
D. The patient has legal blindness
A. The patient sees at 20 feet what a normal person sees at 40
feet
20/40 vision indicates reduced acuity; the patient must be closer
to see what a normal eye sees farther away.
, 10. What is the main purpose of an anti-reflective coating on
lenses?
A. Increase magnification
B. Reduce glare
C. Change lens color
D. Correct astigmatism
B. Reduce glare
Anti-reflective coatings reduce reflections from light sources,
improving vision comfort and clarity.
11. A patient with astigmatism requires which type of lens
correction?
A. Spherical
B. Cylindrical
C. Bifocal
D. Progressive
B. Cylindrical
Cylindrical lenses correct the uneven curvature of the cornea
causing astigmatism.
12. Which type of lens is used for presbyopia?
A. Single-vision
B. Bifocal
C. Concave
D. Cylindrical
B. Bifocal
Bifocals provide multiple focal points, aiding near vision in patients
with age-related lens stiffness.
