  • Exactly 4,582 Chinese American adults who were all 50 years and older underwent complete ophthalmologic examinations, including measurement of presenting and best-corrected visual acuity.

  • The prevalence of vision impairment and blindness was higher in older Chinese Americans compared with younger.

  • The primary causes of vision impairment were cataracts and myopic retinopathy; the primary cause of blindness was myopic retinopathy.
