Giving Compass' Take:

• According to Global Citizen, poor vision is leaving people in poverty and costing the global economy billions, demanding an intervention. Specifically in India, increased access to glasses could not only improve quality of life, but result in $19 billion in growth from productivity alone.

• How can we raise awareness and draw more attention to this issue of access to ocular health? How can donors help?

• Learn how vision is linked to the global goals.

You might not have heard of presbyopia — many of the 1.1 billion people around the world who are affected by it won’t have.

Nevertheless, it’s the most common cause of vision impairment globally, and more than 90% of people living with it who are unable to access treatment are in developing countries.

It’s essentially a decline in near-vision that’s connected to ageing and, as the Global Disability Summit got underway in London for the first time on Tuesday, new research was published about how presbyopia is costing the global economy billions.

A report, published in the Lancet Global Health on Tuesday, is the first time that presbyopia’s workplace effects have been assessed. And the results are pretty astonishing.

The research was funded by Clearly , a global campaign to bring clear vision as quickly as possible to the 2.5 billion people who are living with poor vision — including presbyopia — around the world. Global Citizen has partnered with Clearly in the effort to achieve this ambition.
