Major constraints to program implementationare lack of manpower and monetary resources. In particular, 4 countries (Nigeria, Democratic Republic of Congo,South Africa, and Ethiopia), representing half of the regional population,have received special attention. Several regional planning workshops have taken place, and severalcountries are at various stages of development of national plans for blindnessprevention. A West Africa Advocacy Forum took place in Abidjan, Cote d'Ivoire,in June 2002. The Africa region comprises all the countries of sub-Saharan Africa.VISION 2020 was launched in 2000 in Bamako, Mali, and Pretoria, South Africa.The Africa regional plan was reviewed and adopted in Durban, South Africa,in April 2002. This article summarizes the statusof VISION 2020 at this time and provides a description of what lies ahead. In areas of the world where these focal diseases have been controlled,glaucoma and diabetic retinopathy are included among the targeted conditions.To achieve its goals, VISION 2020 requires the training of adequate numbersof eye care providers at all levels and the establishment of critical infrastructureand appropriate technology ( Table 1).Just as importantly, VISION 2020 has provided the advocacy that is essentialto raise sufficient resources and commitment to attain the goals of the initiative.VISION 2020 is now 4 years into the process. 3 - 5 VISION2020 aims to eliminate avoidable blindness in the world by 2020 and targetsthe world's leading causes of avoidable visual impairment: cataract, trachoma,onchocerciasis, childhood blindness (including vitamin A deficiency), andrefractive error and low vision ( Figure 1). In response to this global need, the World Health Organization (WHO),Geneva, Switzerland, with the International Agency for the Prevention of Blindness(IAPB), London, England, a partnership of eye care organizations, launchedthe VISION 2020: The Right to Sight initiative in 1999. 2 Sinceeye disease is seen largely in older people, the projected doubling of theworld's population older than 50 years to 2 billion by 2020 has profound effectson the number of those with blindness and low vision. Without intervention, the number of individuals with blindness mightreach 76 million by 2020 because of a number of factors, primarily the rapidaging of populations in most countries.
1 Mostof them have lost their sight to diseases that are treatable or preventable.Eighty percent of them live in the lesser-developed world in countries wherechronic economic deprivation is exacerbated by the added challenge of failingvision.

Glaucoma, a progressive eye disease caused by increased pressure in the eye, demonstrates that you can have all the signs of good vision while unknowingly living with an eye disease that is one of the leading causes of blindness in Canada. It should be noted that the quality of your eyesight and eye health are not mutually exclusive. A few of those factors include eye focusing, coordination, movement, teaming, as well as visual perceptual skills and color vision. Optometrists take multiple factors into consideration when determining the quality of your vision. … if the change in vision is to 20/200 or worse, the person will still keep some vision but will be classified as “blind”. If you have 20/60 vision, this means you can see at 20 feet what a person with good vision can see at 60 feet. This simply means that the eye being tested is able to see an object at 20 feet as well as any eye with very good vision. 20/20 vision only represents the clarity of your vision when viewing objects 20 feet in the distance, CNIB explains: In fact, it’s highly probable that many people don’t even know what those numbers means. “I have 20/20 vision” are words you may have uttered while bragging about having tip-top eyesight, however, it’s not that simple.
If you’ve been postponing regular visits to a doctor of optometry because they once told you that you had 20/20 vision, then you should keep reading.
