Linear graphs showing age distribution of cataract.

<p>(A) Age distribution of nuclear cataract and cortical cataract in Korean population. Both types of cataract show a highest incidence at the age of 60–69. (B) Age distribution of posterior subcapsular cataract (PSC) and anterior polar cataract (APC). PSC shows a gradual increase according to age, and APC present a highest peak at the age of 50–59. * PSC = posterior subcapsular opacity; APC = anterior polar cataract.
