Make Vision Count – WSD 17

Where there is no vision, people perish.  As the world celebrates this year’s World Sight Day, there is a global call for Individuals, Nations, Stakeholders to make vision count. Our world depends on it. The burden of visual impairment and blindness is devastating; it impoverishes people and affects the economic progress of Nations.

Visual Impairment has become a Global Health Challenge.


 Before we go right over to see the figures one nation at a time, let’s get some basic understanding of certain visual terms.

Visual impairment or low vision is a severe reduction in vision that cannot be corrected with standard glasses or contact lenses and reduces a person’s ability to function at certain or all tasks. it could be Mild impairment or Moderate to Severe Visual impairment (MSVI)

Blindness is a lack of vision. It may also refer to a loss of vision that cannot be corrected with glasses or contact lenses. Partial blindness means very limited vision. Complete blindness means light cannot be perceived. Legal Blindness means the level of vision loss that has been legally defined as blindness, varies from Country to Country
