This condition is also known as nearsightedness:
Contact [7]

Answer:

The correct answer is B. Myopia is also known as nearsightedness.

Explanation:

Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.

A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.
