Question

A person with "near-sightedness" or myopia sees near objects clearly but sees blurry far objects. The lens and cornea do the refracting of the eye, with the cornea doing the majority of the refracting. Light needs to hit the back of the eyeball to be proposed correctly. a. For the near-sighted person, does light from far away focus on the back of the eyeball? b. The shape of the cornea and lens is often the problem for near-sighted people. Typically, their cornea and lens are "too curvey". Where would light from distant objects focus with this problem? What kind of lens would you use to correct this problem? c. Farsighted people can see far objects clearly, but not near objects. Their lens/cornea/shape of eyeball is not curvey enough. Where does light from near objects focus for people with this issue? What kind of lens would correct this problem?
