An office assistant tells the nurse his job requires him to work at his computer for 7 to 8 hours each day. Which statement indicates that the nurse's teaching about preventing eyestrain has been successful?
a. "I will wear protective goggles while working."
b. "I will eat more carrots and cooked spi-nach."
c. "I will close my eyes every few hours."
d. "I will instill artificial tears each hour while working."
C
To prevent eyestrain, the patient should rest the eye muscles periodically when working at the computer or performing any activity that demands intensive visual effort. Resting the eye mus-cles every several hours helps prevent eye fatigue. Protective goggles do not help prevent eyes-train. Nutrients such as lutein and zeaxanthin are found in carrots and cooked spinach and are good for the eyes but do not reduce eyestrain. Overuse of artificial tears is not recommended, and proper usage works to combat dry eyes.
