Clearly: How a 700 Year Old Invention Can Change the World Forever

by James Chen

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 Chen asks why this should be and describes his quest to answer that question.

In the book, James Chen reveals the personal stories of some of those afflicted and identifies the barriers to universal access to vision correction.

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 our mission to help everyone in the world see clearly.


If we fail to act, those left behind will never catch up.

Gordon Brown, Former UK Prime Minister


“This book is just what we need to kickstart action and drive the change needed – to work together so no one is left behind for lack of a pair of glasses.”

Justin Forsyth, Former Deputy Executive Director, UNICEF

“This is the compelling story of how one man with a bold vision and an unwavering passion invested his resources to make his dreams a reality.”

Professor Agnes Binagwaho, Former Minister of Health, Rwanda

“Health and economic ministers everywhere no longer have an excuse for ignoring the problem of correctable poor vision.”

Andrew Mitchell, Former UK Secretary of State for International Development

“In a world where we have made unprecedented progress, it is unforgivable that so many still struggle to see clearly. The time for the whole world to see has come.”

Helle Thorning-Schmidt, CEO of Save the Children International, Former Prime Minister of Denmark
