The Cause 

of blindness 

Blindness

Blindness, by definition, is the significant loss of useful sight. Imagine not being able to make out the face of a person 3 feet away from you, or having severe tunnel vision and lacking any peripheral vision. Being blind doesn't mean that you see total blackness, blindness is different for all those affected since there are multiple diseases that can lead to blindness. According to the World Health Organization (WHO) an individual can be functionally blind if it affects the activities of daily functioning (ADL). This can have a serious effect on those living in lower income countries since much of their livelihood depends on labour.

Cause 

Worldwide, 285 million people live with significant vision impairment, of which 39 million are blind. The vast majority of those effected live in low socioeconomic and impoverished areas, not having access to proper healthcare or even sanitation. Globally, uncorrected refractive errors (URE) and un-operated cataracts are the top two causes of visual impairment making up 80% of all visual impairment. All of which are easily preventable with proper medical attention. Blindness is highly prevalent in developing nations. Globally, 90% of those visually impaired individuals live in impoverished areas. They endure malnutrition, inadequate health care, inadequate education services, lack of clean water, and poor sanitary conditions. All these factors contribute to the increasing rate of eye disease in these regions. In the least-developed countries, in particular Sub-Saharan Africa, cataracts is responsible for half of all avoidable blindness. Other causes include glaucoma, corneal opacities, trachoma, childhood blindness and onchocerciasis. For cataracts, a simple, low cost, one time procedure can restore full sight to the patients and give them their life back. However in too many places this procedure is not available. GIVE intends to change that.

Cataracts

A cataract is a cloudy or opaque area in the normally transparent lens of the eye. A cataract occurs when clumping of cells or protein causes a cloudy or opaque area in the transparent lens. As the lens clouds over, vision is impaired.
