Which of the following is NOT a risk factor for cataracts?

Regular exercise is not considered a risk factor for cataracts; instead, it can be associated with protective health benefits. Engaging in regular physical activity can improve overall health and may contribute to a lower risk of developing various health conditions, including certain types of eye diseases. In contrast, diabetes, sun exposure, and smoking are all established risk factors for cataracts.

Diabetes can lead to changes in the lens of the eye, increasing the risk of cataract formation. Excessive exposure to ultraviolet (UV) light from the sun is known to damage the lens, making it more prone to developing cataracts. Smoking introduces harmful chemicals into the body that can accelerate the formation of cataracts, as well as increase the likelihood of other eye diseases. Hence, while maintaining a healthy lifestyle, including regular exercise, is beneficial, it is not linked to an increased risk of cataracts.
