WHO: 2,2 billion people worldwide with vision impairment or blindness

The World Health Organization in its latest report has said that at least 2.2 billion people worldwide have vision impairment or blindness, of which over 1 billion cases could have been prevented or have yet to be addressed. This is because they do not get the care they need for conditions like short and far-sightedness, glaucoma, and cataracts.
