WORLD SIGHT DAY 2022 | EYE-QUIZ!

World Sight Day is an International Day of Awareness, held annually on the second Thursday of October. This year, World Sight Day is Thursday, 13 October 2022. World Sight Day is coordinated by the International Agency for the Prevention of the Blindness (IAPB).

World Sight Day is a reminder to you, to love your eyes. It is an invitation to think about the importance of your eye health and how you can protect it and keep it healthy now and long into the future.

Eye health impacts education, employment, quality of life, poverty and so many other Sustainable Development Goals. This World Sight Day, organisations and the public should come together to encourage governments, corporations, institutions and individuals to actively call for universal access to eye health.
