Question 4

Cataracts are an eye condition characterized by the clouding of the lens, which prevents light from clearly reaching the retina. The development of cataracts is highly correlated with age.

A clinical study monitored a cohort of patients to investigate this relationship. The findings are summarized in the table below:

Age category (years)Prevalence of cataracts in the study population (%)
< 450.8
45–544.3
55–6416.1
65–7438.6
≥ \ge\,≥ 7568.2

Explain one conclusion that can be made about the occurrence of cataracts, using data from the table.
