Eyeglasses and Hearing Aids Quiz
Questions: 16 · 10 minutes
1. A 48-year-old can still see distant objects clearly but increasingly holds reading material farther away. Which common age-related change best fits this pattern?
Myopia, which mainly makes distant objects appear blurred
Presbyopia, a gradual loss of the eye’s ability to focus up close
Astigmatism caused specifically by reading in dim light
Color-vision deficiency that begins in middle age
2. What is generally the best routine method for cleaning coated eyeglass lenses?
Rinse away particles, use lens-safe cleaner if needed, and dry with a clean microfiber cloth
Polish them with a dry shirt sleeve until fingerprints disappear
Use household glass cleaner and a paper towel
Soak them in very hot water to loosen oils
3. A hearing aid begins producing a repeated whistling sound when it is worn. What is a sensible first interpretation and response?
The user’s hearing has necessarily worsened overnight, so the volume should be maximized
Whistling proves that the device is working correctly and needs no attention
The battery is always overcharged and must be punctured before disposal
Feedback may result from fit, blockage, or settings, so check placement and seek professional help if it persists
4. Which habit is most likely to create fine scratches on eyeglass lenses over time?
Storing the glasses in a protective case when not in use
Frequently wiping dry, dusty lenses with paper tissues or clothing
Rinsing dust from the lenses before wiping them
Using a clean microfiber cloth after applying lens-safe cleaner
5. A person has worn a new eyeglass prescription as directed, but persistent headaches and blur continue beyond the expected adjustment period. What should they do?
Bend the frames repeatedly until the lenses seem better aligned
Wear an older pair over the new glasses to combine their correction
Contact the eye-care provider so the fit, measurements, prescription, and eye health can be reviewed
Assume that discomfort always proves the prescription is becoming stronger
6. What does astigmatism usually involve?
An irregular curvature of the cornea or lens that affects how light focuses
A temporary inability to see color after using a screen
A complete loss of near focusing caused only by aging
A condition in which the pupils are permanently different colors
7. A child may have swallowed a hearing-aid button battery. What should an adult do?
Contact emergency services or a poison center immediately and follow urgent instructions
Try to make the child vomit before asking for advice
Monitor the child at home because small batteries usually pass harmlessly
Offer food and wait to see whether stomach discomfort develops
8. A hearing aid sounds muffled after being exposed to moisture. What is the safest general response?
Dry it quickly in a microwave or conventional oven
Insert a pin into the microphone opening to clear it
Remove it from use, follow the manufacturer’s drying guidance, and check for blocked openings
Submerge it in cleaning solution while the battery remains installed
9. Which statement most accurately describes what modern hearing aids can do?
They restore hearing to exactly the same level as normal hearing in every setting
They process and amplify sound to improve access to it, but they do not recreate normal hearing
They make every sound equally louder so the brain does not need to adapt
They work mainly by eliminating all background noise
10. On a standard audiogram, what is commonly shown along the horizontal axis?
The age at which hearing changed
The physical size of the ear canal
Sound frequency, from lower to higher pitches
The number of words used during testing
11. Someone wears everyday prescription glasses while doing work that could send fragments toward the eyes. What should they know?
Any prescription lens provides the same impact protection as safety eyewear
Thick frames alone make ordinary glasses suitable for hazardous work
Closing one eye provides adequate protection if debris starts moving
They need appropriately rated protective eyewear; ordinary prescription glasses may not provide sufficient impact protection
12. Someone notices a sudden major loss of hearing in one ear over several hours. What is the most appropriate response?
Seek prompt medical assessment because sudden hearing loss can be time-sensitive
Increase headphone volume to test whether sound returns
Wait until the next routine hearing test, even if the change continues
Clean deep inside the ear canal with a cotton swab
13. On an eyeglass prescription, what does “OD” conventionally identify?
The left eye
The right eye
The distance between the pupils
The lens coating type
14. In a noisy restaurant, a hearing-aid user is struggling to understand a companion. Which strategy is most likely to help?
Ask the companion to shout from across the table
Turn away from the companion so both ears receive more background sound
Cover the hearing-aid microphones to reduce competing voices
Face the companion, move closer, improve lighting, and use an appropriate listening program if available
15. Earwax is visible on the outside of a hearing aid or removable earmold. What is the best general cleaning approach?
Push a cotton swab into the ear canal to remove the source
Scrape every opening with a needle or metal pin
Use the approved tools and manufacturer’s instructions, and ask a professional about persistent blockage
Wash the complete electronic device under running water
16. How do progressive eyeglass lenses differ from ordinary single-vision lenses?
They automatically darken indoors and become clear outdoors
They correct hearing and vision at the same time
They use the same corrective power throughout the entire lens
They provide a gradual range of viewing powers for different distances within one lens
