Living with visual impairment and methods to support healthy behaviors in people with visual impairment

摘要

The article by An and co-authors in this issue of Ophthalmic Epidemiology, highlights a couple of issues: (1) the concept of temporality, a regular concern in cross-sectional epidemiologic studies, and (2) secondary public health concerns related to visual impairment, which usually vary little within and between developed and developing nations. Little has been written about the issue of secondary public health needs related to visual impairment, so the paper by An and colleagues also highlights the need for more research in this area and for other causes of visual impairment.
