Vision and Hearing Defects Quiz
Preview:
What is a common method to correct myopia?
A. Cochlear implants.
B. Prescription eyeglasses or contact lenses.
C. Regular ear cleaning.
D. Dietary supplements.
What is the mechanism by which myopia develops?
A. The lens becomes more convex, focusing light behind the retina.
B. The lens becomes less convex, focusing light in front of the retina.
C. The eyeball lengthens, causing light to focus in front of the retina.
D. The eyeball shortens, causing light to focus behind the retina.
What typically causes color blindness?
A. Frequent swimming without goggles.
B. Long-term exposure to loud sounds.
C. Genetic defects in the cones of the retina.
D. Reading in dim light.
Which statement about refractive errors is correct?
A. They are primarily caused by auditory issues.
B. They can be corrected by cognitive behavioral therapy.
C. They involve the improper bending of light by the eye.
D. They are unrelated to the eye’s anatomy.
What is a common effect of aging on hearing?
A. Improved clarity in hearing high-pitched sounds.
B. Decreased ability to distinguish colors.
C. Increased difficulty in hearing low-pitched sounds.
D. Reduced ability to hear high-pitched sounds.
Which is a factor that does NOT contribute to conductive hearing loss?
A. Aging of the auditory nerve.
B. Buildup of earwax.
C. Infections in the ear.
D. Allergies causing blockage in the ear.
What is an effective way to prevent vision defects related to UV exposure?
A. Wearing broad-brimmed hats.
B. Using earplugs in noisy environments.
C. Increasing intake of fatty acids.
D. Regularly changing contact lens solutions.
What is NOT a symptom of aging affecting hearing?
A. Difficulty understanding spoken words, especially against background noise.
B. A constant ringing sound in the ears.
C. Enhanced perception of high-frequency sounds.
D. Needing to increase the volume on the television.
Which of the following does NOT describe myopia?
A. Nearsightedness.
B. Farsightedness.
C. Light focusing in front of the retina.
D. Blurry vision for distant objects.
What is myopia and how does it affect vision?
A. A condition where distant objects appear blurry because the eyeball is too short.
B. A condition where distant objects appear blurry because the eyeball is too long.
C. A condition where near objects appear blurry because the eyeball is too long.
D. A condition where near objects appear blurry because the eyeball is too short.
What are refractive errors in vision primarily due to?
A. Changes in the auditory canal.
B. Alterations in the shape of the cornea or lens.
C. Damage to the optic nerve.
D. Fluctuations in ambient lighting.
Which of the following is NOT a cause of color blindness?
A. Long-term exposure to sunlight without eye protection.
B. Hereditary factors.
C. Chemical exposure.
D. Aging.
What is an effective prevention strategy for minimizing vision defects?
A. Regular exposure to loud noises.
B. Frequent eye examinations and proper eye care.
C. Avoiding outdoor activities.
D. Consuming less water.
How does the mechanism of myopia lead to blurry distant vision?
A. The cornea flattens, spreading the light too wide on the retina.
B. The lens loses its elasticity, failing to properly focus light.
C. The eyeball elongates, causing light rays to focus before reaching the retina.
D. The retina moves closer to the lens, distorting the light focus.
What is the primary cause of color blindness?
A. Frequent headaches.
B. Genetic predisposition.
C. Overuse of corrective lenses.
D. Lack of dietary vitamins.
