Question

If the lens of a person’s eye is removed because of cataracts (as has been done since ancient times), why would you expect an eyeglass lens of about 16 D to be prescribed?

a. The eye becomes farsighted after cataract removal; a converging lens compensates.
b. The eye becomes nearsighted after cataract removal; a diverging lens compensates.
c. The eye loses its ability to accommodate after cataract removal; a converging lens helps with close vision.
d. The eye's focal length increases after cataract removal; a diverging lens increases magnification.

Answer 1

After cataract removal, a converging lens of about 16 D is prescribed because the eye becomes farsighted and a converging lens helps compensate for this.

Step-by-step explanation:

After the removal of the lens due to cataracts, the eye may become farsighted. To compensate for this, a converging lens of about 16 D (diopters) is prescribed. The converging lens helps to bring close objects into focus for clear vision

For example, a person who has had cataract surgery may find it difficult to see objects up close without the help of eyeglasses. The prescribed eyeglass lens helps to correct this issue by converging the light rays to bring the close objects into focus.
