the most cost-effective interventions in health care Infectious causes
of blindness are decreasing as a result of public health interventions
and socio-economic development.
Blinding trachoma now affects fewer than 80 million people, compared to
360 million in 1985 Aging populations and lifestyle changes mean that
chronic blinding conditions such as diabetic retinopathy are projected
to rise exponentially Women face a significantly greater risk of vision
loss than men Without effective, major intervention, the number of
blind people worldwide has been projected to increase to 76 million by
2020 Dark & Light aims at the eradication of preventable and
treatable eye diseases. Early discovery and proper treatment can
