    Incomplete question. However, I provided some information about when a converging or diverging lens is used. The common ones are:

    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.

    Covergent lens: In a case where the person has a condition that prevents him from seeing close objects clearly while distant objects may be clear is called Farsightedness (hyperopia).
