Firstly, cataracts are the clouding of the lens inside our eyes, known as cataracts. Cataracts are not contagious. Based on the cause, cataracts can be classified into age-related cataracts (previously referred to as senile cataracts), metabolic cataracts, secondary cataracts, traumatic cataracts, and radiation cataracts. The most common type in clinical settings is age-related cataracts, which are commonly seen in middle-aged and elderly individuals over fifty years old. Its clinical presentation is a painless, gradual decline in vision. Currently, the only effective treatment is surgical intervention.
