Question

Which condition may cause farsightedness?

an eyeball that is too long
a cornea that is not curved enough
an iris that cannot expand
a pupil that is too wide

Answer 1

It would be that the cornea is not curved enough, thus not allowing the pupil to expand to perceive further distances clearly. :)

Answer 2

The correct answer is a cornea that is not curved sufficiently.

Step-by-step explanation:

Hyperopia or farsightedness refers to a condition or state of vision in which far off objects are generally seen evidently, however, the close objects do not come into focus properly. The condition takes place in case if the cornea has too little curvature or if the eyeball is too short, thus, the light getting inside the eye does not get focused accurately.
