What is the primary risk factor for cataracts?

• A. Genetic predisposition
• B. Aging
• C. Excessive ultraviolet light exposure
• D. High blood pressure

Answer: (B)

Aging is recognized as the primary risk factor for cataracts due to the natural process of lens changes that occur over time. As people age, the proteins in the lens of the eye begin to break down and clump together, resulting in cloudiness and impacting vision. This process typically progresses gradually, and the likelihood of developing cataracts increases significantly with advancing age, making it the most prominent factor. While genetic predisposition, excessive ultraviolet light exposure, and high blood pressure can contribute to the development of cataracts, they are not considered the primary risk factor. Genetic factors might increase susceptibility, and UV exposure can accelerate lens damage, but the overall age-related changes in the eye are the most critical influence on cataract formation. High blood pressure may have some association with overall eye health, but it does not have the same direct correlation with cataract development as aging does.
