Do cataracts appear when people are old?

Cataracts are a common eye disease and are usually age-related,

as

the lens in the eye becomes clouded with age, leading to decreased vision. However, the occurrence of cataracts is also affected by many other factors, such as genetics, eye diseases, eye injuries, and systemic diseases. Therefore, although older people are at higher risk of developing cataracts, not all older people develop cataracts.
