Question: 1 / 400

What is the common age for onset of cataracts?

After the age of 30

Typically after the age of 60

Cataracts commonly develop with aging, and the typical onset is after the age of 60. As people age, changes occur in the lens of the eye, leading to the gradual clouding characteristic of cataracts. This condition can result from various factors, including natural aging processes, prolonged UV exposure, certain medical conditions, and lifestyle choices, but age remains the most significant risk factor.

Other age ranges cited, such as before the age of 50 or in early childhood, are far less common for cataract development and may be associated with specific genetic conditions or factors rather than the general population's experience. The indication that cataracts typically arise after 60 aligns with epidemiological studies and clinical observations, underscoring the age-related nature of this condition.
