Dyson Award winners: Glaucoma glove and bottle scanner

A kit that allows people to test for glaucoma at home and a scanner that helps recycle plastic bottles are among the winners of the international James Dyson Award.

Usually won by just one student innovator, this year's competition had three winners, after a record number of entries. Each receives £30,000 in prize money.

Sir James was pleased to see "the enthusiasm with which young people tackle the world's problems".

"Commercialising an idea is very hard and I hope that the awareness of the award drives, as well as the financial support it provides, will give these ideas a springboard to success," he said.

Eye pressure
The glaucoma glove, which won the international award, was inspired by the diagnosis of inventor Kelu You, and her father, with the condition.

Along with Si Li and David Lee, from the National University of Singapore, she came up with a less invasive and more accessible way to monitor eye pressure.

Glaucoma is the second leading cause of blindness worldwide and half a million people in the UK alone have it. There is no cure - but if diagnosed and treated early, blindness can be prevented. Monitoring for intraocular pressure is key to diagnosis but requires hospital visits.
