Which statement is true regarding cataracts?

• A. It is an excess of fluid in the eye
• B. It primarily affects the iris muscle
• C. It leads to a clouding of the lens
• D. It is the absence of the retina

Answer: (C)

Cataracts refer to the condition characterized by the clouding of the lens of the eye. The lens is crucial for focusing light onto the retina, and when it becomes cloudy due to cataracts, it can significantly impair vision. This condition often develops slowly and can lead to symptoms such as blurred vision, glare from lights, and difficulty seeing at night. The clouding occurs primarily because of changes in the proteins that make up the lens, leading to a reduction in clarity. As cataracts progress, they can affect a person's quality of life significantly, as clear vision is essential for daily activities. Cataracts can be caused by a variety of factors, including aging, exposure to UV light, smoking, and certain medical conditions. Ultimately, the surgical removal of the cloudy lens and replacement with an artificial lens is a common and effective treatment.
