For the last two weeks, we’ve been introducing you to real stories of those who are using Xperia Z3 to do great things with their smartphone. Last but not least, we’re delighted to reveal ‘Peek’ – the final film in the three-part Demand Great series. The films were created to showcase how three every-day heroes turn situations from good to great using the Xperia Z3, and ‘Peek’ tells the story of a truly exceptional collaboration.

The video is centered on Stewart Jordan, the cofounder of Peek – a portable eye examination kit which consists of apps loaded on to smartphones, including Xperia Z3, and a clip-on adapter allowing ophthalmologists to diagnose eye conditions anywhere in the world.

Without treatment and contact lenses, Stewart himself would be diagnosed as blind. Stewart now wants to help people who are in the same position as him, but without access to healthcare when they desperately need it.

Peek’s technology, combined with the phone’s 20.7megapixel camera and low-light capabilities, ensures that the highest quality images of patients’ eyes can be used to accurately diagnose their condition. Stewart has introduced Peek to local healthcare workers in Guatemala, which will help to ensure that more patients in rural areas are diagnosed than would have previously ever been found.

Along with its innovative camera technology, the phone’s durable design, including dust-tight and waterproof capabilities* makes it the best tool to ensure it functions in the extremes of the Guatemalan weather – which varies from dry and dusty to monsoons. Its extensive battery life means that it can work for long periods of time out in the country, making it the perfect partner for the work that Peek has set out to accomplish.

“It is difficult for the bulky equipment that you find in a hospital to be transported out there,” says Stewart. “But with Peek and a smartphone we can send just one person almost anywhere and they can perform some high quality eye examinations.”

With 39 million people worldwide suffering from blindness, Peek bridges the gap and takes healthcare where it’s most needed. Stewart’s story shows how his desire to go above and beyond, using his pioneering app and Xperia Z3’s exceptional technology, have combined to achieve something great.

The ongoing collaboration between Peek and Sony Mobile will see over 150 smartphones donated to areas including Kenya, Mali, Tanzania, India and Guatemala to support Peek’s initiative in making eye examinations more accessible for those in even the remotest of settings.
