Question

Complete the passage with the options that explain why converging lenses are used to correct farsightedness (hyperopia), whereas diverging lenses are used to correct nearsightedness (myopia).

In order to see an object, the cornea and lens of the eye form an image directly on the retina. The eyes of a nearsighted person cause the light rays of a ________ object to converge too __________ and therefore focus the image _________ the retina. A diverging lens placed in front of a nearsighted eye compensates for the ___________ convergence so that an image forms properly on the retina. The eyes of a farsighted person cause the light rays of a __________ object to converge too _________ and therefore focus the image _________ the retina. A " converging lens placed in front of a farsighted eye compensates for the __________ convergence so that an image forms properly on the retina.

Answer 1

Step-by-step explanation:

In order to see an object, the cornea and lens of the eye form an image directly on the retina. The eyes of a nearsighted person cause the light rays of a distant________ object to converge too much________ and therefore focus the image __before_______ the retina. A diverging lens placed in front of a nearsighted eye compensates for the _greater__________ convergence so that an image forms properly on the retina. The eyes of a farsighted person cause the light rays of a _nearby_________ object to converge too _less________ and therefore focus the image __behind_______ the retina. A " converging lens placed in front of a farsighted eye compensates for the __lesser________ convergence so that an image forms properly on the retina.

In case of person suffering from near nearsightedness , convergence of light is too much so light gets focused right before retina . It is corrected by diverging lens . Opposite is the case with person suffering from far farsightedness.
