Vision in life should not be taken for granted. Vision is only one of our five senses, but we use and need it more than all the other senses put together. We must take care of it. Get the proper amount of rest and sleep. This will help build the eyes' resistance to irritation and fatigue.
Proper nutrition is essential.
A well-balanced diet promotes good physical health, and it is good physical health that we depend on for our eyes. Good lighting will help to increase your visual efficiency. Make sure you have good light for reading and avoid glare and shadows. Do not read by ceiling light only. Your reading light should be no farther than three feet from your reading material.
