In which age group is the incidence of cataracts most commonly observed?

The incidence of cataracts is most commonly observed in adults over 65 years of age. This is primarily due to the natural aging process, which affects the lens of the eye over time. As people age, the proteins within the lens can break down and clump together, leading to clouding that impairs vision—a condition known as a cataract. Although cataracts can develop at younger ages due to factors like trauma, certain medications, or underlying health conditions, the majority of cataract cases are related to aging, making the age group of over 65 significantly more affected.

In contrast, the other age groups listed, such as infants and teenagers, typically do not experience cataracts at the same frequency. While congenital cataracts can occur in infants, they are relatively rare. Similarly, cataracts in teenagers are quite uncommon and tend to be associated with specific health issues rather than age. Adults aged 40-60 may start to notice changes in vision, but the onset of cataracts generally becomes much more prevalent in those older than 65. Thus, adults over 65 represent the age group where cataracts are most frequently diagnosed.
