Question

A person who can see near objects clearly but cannot see clearly the distant objects is called hyperopia.
A) True.
B) False.

Answer 1

Hint: The common diseases of eyes are either the human being cannot see far objects or the human eye cannot see near objects. Also in old ages human eye muscles get so weak that the human eye cannot see near as well as far objects clearly.

Complete step by step answer:
The eye disease in which people can see near objects clearly and cannot see far objects clearly is known as Myopia and the diseases in which people can see far objects clearly and cannot see near objects clearly is known as hyperopia. In the disease myopia the human eyeball becomes bigger than the normal size so the eyeball therefore cannot focus on the retina of the eye instead it focuses in front of the retina the lens which can correct this disease is a double focal concave lens. Whereas in the disease hyperopia the eyeball size decreases from the normal size and therefore the power of the eye lens decreases and therefore image is formed behind the retina so the lens required to correct is a double focal convex lens.

Therefore, the given statement is false. Hence, option B is correct.

Note:
There are many diseases related to the eyes but the most common eye disease is myopia and hyperopia. In myopia the eye lens gets bigger and therefore the power of the lens is more and therefore a diverging lens is required to focus rightly on the retina. In hyperopia the eye lens shrinks due to which the power of the eye becomes very less and therefore a converging lens is required to rightly focus the image on the retina.
