Question

Mrs. Taylor has always had perfect vision until recently. She noticed around her 60th birthday that she was having difficulty threading her needles. This form of farsightedness, known as presbyopia, is the result of:

a) Lens becoming brittle and inflexible
b) An elongated eyeball
c) Irregular corneal shape
d) Retinal damage

Answer 1

Presbyopia is a vision problem associated with aging in which the eye gradually loses its ability to focus on close objects. The cause of presbyopia may be due to the lens becoming less elastic with age and the muscles controlling the lens losing power. This form of farsightedness is not caused by retinal damage, an irregular corneal shape, or an elongated eyeball.

Step-by-step explanation:

Presbyopia is a vision problem associated with aging in which the eye gradually loses its ability to focus on close objects. The precise cause of presbyopia is not known for certain, but evidence suggests that the lens may become less elastic with age, and the muscles that control the lens may lose power as people grow older. This form of farsightedness is not caused by retinal damage, an irregular corneal shape, or an elongated eyeball. Instead, it is primarily the result of the lens becoming brittle and inflexible.
