Poor vision is the largest unaddressed disability in the world today. An estimated 2.5 billion people, a third of the global population, suffer from poor vision because they don’t have access to a simple pair of glasses – a solution that has been around for centuries.

It’s an issue the world has ignored, even though tackling it would transform countless lives – helping children to learn, improving gender equality, increasing productivity, and ultimately reducing poverty.

The world is on the cusp of a new technological revolution but those without good sight cannot participate in this progress and will fall further behind. Insufficient funds are available to tackle the issue yet helping the whole world see would save trillions of dollars in health costs and lost productivity. In Clearly, James asks why this should be and describes his quest to answer that question.

He delivers a passionate call to governments and international institutions to act, and appeals to the worlds of business, technology, and medicine to come together and find a solution to this global problem.

All proceeds go towards the Clearly campaign and its mission to help everyone in the world see clearly.



The release of James' book was followed by a supplementary report focusing on the impact of poor vision in rural China.
