What’s behind the global rise in short-sightedness?

Chris Hammond and Katie Williams
Short-sightedness usually develops in childhood, and occurs when the eye grows excessively long
Short-sightedness usually develops in childhood, and occurs when the eye grows excessively long

Writing on The Conversation, Chris Hammond and Katie Williams of King’s College, London, consider the potential factors behind a global increase in myopia

Increasing rates of myopia will lead to more blindness in the future Over the last century, myopia (short-sightedness) has risen to epidemic prop
