What is the biggest risk factor for the development of cataracts?

Hypertension
Diabetes
Advancing age
Excessive exposure to sunlight

The correct answer is: Advancing age

Advancing age is recognized as the biggest risk factor for the development of cataracts due to the natural aging process of the eye. As individuals grow older, changes occur in the proteins within the lens, leading to clouding and the formation of cataracts. This process is gradual and typically becomes more pronounced in people over the age of 60, which is why age is a primary risk factor. While conditions such as hypertension and diabetes can influence eye health and potentially contribute to cataract formation, their impact is not as significant as that of aging. Similarly, excessive exposure to sunlight can increase the risk of cataracts by causing damage to the lens through UV radiation, but this risk is often more manageable compared to the inevitable effects of aging. Therefore, advancing age remains a prominent factor in cataract development, making it the key focus within this context.
