Question

I don't know how to use that term in this explanation, can someone help me? I'd deeply appreciate it! :)

Explain how lenses in glasses or contacts need to change the light waves that enter the eye for a person who is

Nearsighted
Farsighted

Use the terms convex and concave in your answer.

Answer 1

Glasses or contact lenses correct vision because they allow the eye to focus light in the right spot on the retina the spot that produces the clearest image. Because everyone's eyes are different, a pair of glasses that makes one person see wonderfully may look terribly blurry to someone else.

Nearsighted- unable to see things clearly unless they are relatively close to the eyes, owing to the focusing of rays of light by the eye at a point in front of the retina; myopic.

Farsighted- a common vision condition in which you can see distant objects clearly, but objects nearby may be blurry. The degree of your farsightedness influences your focusing ability.
