Conditions

Interventions

BEHAVIORAL

Enhanced Intervention Using Patient Navigators

Enhanced support by patient navigators assisted with follow-up eye exam appointment scheduling and arranging transportation over a 1-year period.

OTHER

Usual Care

Usual Care subjects who failed the screening and needed vision correction were given an eyeglasses prescription and a list of optical shops within 1 mile from their home. These subjects did not receive enhanced support. Scheduling this initial appointment will allow tracking of adherence.
