What is the normal vision loss associated with aging called?

1. Presbyopia

2. Myopia

3. Glaucoma

4. Cataracts

The correct answer is: Presbyopia

The term used to describe the normal vision loss associated with aging is presbyopia. As individuals age, typically starting in their 40s, the lens of the eye becomes less flexible, making it more challenging to focus on close objects. This condition is particularly evident when reading or doing tasks that require near vision. Presbyopia is a common and natural part of the aging process, distinguishing itself from other conditions that can cause vision problems. Myopia, for instance, is nearsightedness, usually developing during childhood or adolescence, while glaucoma refers to increased intraocular pressure that can lead to optic nerve damage. Cataracts involve the clouding of the lens, which can affect vision but are not classified as a normal age-related change. Understanding presbyopia helps in recognizing how age affects optical function and is crucial for providing appropriate management strategies for those experiencing changes in their vision.
