World Sight Day
World Sight Day, observed annually on the second Thursday of October, is a global event meant to draw attention to blindness and vision impairment. It was originally initiated by the SightFirstCampaign of Lions Club International Foundation in 2000. It has since been integrated into VISION 2020 and is coordinated by the International Agency for the Prevention of Blindness (IAPB) in cooperation with the World Health Organization. The theme for World Sight Day 2014—held on October 9, 2014—was "No more Avoidable Blindness". It took place on the second Thursday in October 2014. World Sight Day, 2000–present
