Two thirds of the world's blind are women
Almost two thirds of the world's blind are women, finds an analysis of published research on global blindness in the British Journal of Ophthalmology. In 2000, Africa had over 10 times the rate of blindness of the rest of the world. (2001-11-28)

Night blindness may explain fear of the dark
Fear of the dark is a common complaint in children and is often attributed to attention seeking behaviour. Yet, researchers in this week's BMJ suggest that it may be due to night blindness - a diagnosis which can be easily missed. (2003-01-23)

Blindness from smoking terrifies teens, but few realize the two are linked
Teenagers fear blindness more than lung cancer or stroke, but nine out of 10 don't know that smoking can rob them of their sight in later life, reveals research published ahead of print in the British Journal of Ophthalmology.

Rare cases of restored vision reveal how the brain learns to see
By testing formerly blind patients within weeks of sight restoration, Sinha and his colleagues found that subjects had very limited ability to distinguish an object from its background, identify overlapping objects, or even piece together the different parts of an object. The patients gradually improved over time, and the new study suggests that dynamic information -- that is, input from moving objects -- is critical to the brain's ability to learn to segregate objects from their backgrounds (a task known as visual integration). (2009-09-17)

'Color blind' policies could make diversity harder to achieve
Whether it be growing concerns about bias or recognition of the value of diversity, many organizations and institutions have elected to de-emphasize race or remove it entirely from their decision-making processes.
