When caring for an elderly client it is important to keep in mind the changes in color vision that may occur. What colors are apt to be most difficult for the elderly to distinguish?
a. Red and blue.
b. Blue and gold.
c. Red and green.
d. Blue and green.
Answer D.
The elderly are better able to distinguish between red and blue because of the difference in wavelengths. Red and green color blindness is an inherited disorder that is unrelated to age. The elderly have poor blue-green discrimination. The effects of age are greatest on short wavelengths. These changes are related to the yellowing of the lens with age.
