The 42-year-old client with presbyopia asks her nurse how corrective lenses will help her problem. What is the nurse's best response?
A. "This type of problem cannot be helped with corrective lenses."
B. "The correct lenses will be needed for both near and distance vision."
C. "The corrective lenses will need to be used for reading and close work only."
D. "The corrective lenses will not change your near vision and will be needed for distance only."
C
Presbyopia is caused by stiffening of the lens as a result of water loss as the lens ages. Conse-quently, the lens does not refract as well and light waves converge behind the retina, a condition similar to "farsightedness""(hyperopia). The condition makes near vision blurry. People who are naturally nearsighted may have an improvement in distance vision. People who had normal vision before presbyopia do not experience a change in distance vision. Corrective lenses for presbyopia increase light wave refraction and are used for reading or close work.
