Explanation:

In other to correct eyesight problems certain types of lenses are used depending on the condition.

Diverging lens: If the individual is suffering from nearsightedness (myopia); a condition that prevents a person from seeing distant objects clearly, but is able to see close objects clearly, then a divergent lens may be used to correct his eyesight.
