Explanation:
The condition is usually caused by an elongation of the eyeball that occurs over time. Farsightedness (hyperopia) is the opposite of myopia, and is usually caused by shortening of the eyeball. Astigmatism is an imperfection of the cornea preventing part of it from focusing light onto the retina.
