Visual error in old age is known as

The correct answer is Presbyopia

Explanation:

• Presbyopia is a common visual condition that occurs as a natural part of aging, typically beginning around the age of 40 or older.
• The condition is characterized by a gradual loss of the eye's ability to focus on nearby objects, making activities such as reading or using a smartphone more challenging.
• This is due to the hardening of the lens in the eye and weakening of the ciliary muscles, which reduces the lens's flexibility to adjust its shape for near vision.
• It is a normal physiological change and not considered a disease.
• Presbyopia can be corrected using reading glasses, bifocals, progressive lenses, or contact lenses. Surgical options like LASIK or lens implants are also available in some cases.

Other Options:

• Myopia: This is also known as nearsightedness. It is a refractive error where distant objects appear blurry because light focuses in front of the retina. Myopia typically develops in childhood or adolescence and is unrelated to aging.
• Hypermetropia: Known as farsightedness, it is a refractive error where nearby objects appear blurry because light focuses behind the retina. It is not directly related to aging but is a congenital or developmental condition.
• Astigmatism: This is a refractive error caused by an irregularly shaped cornea or lens, leading to distorted or blurred vision at all distances. It is not specifically related to aging and can occur at any age.
