Most of us blink without thinking about it – we do it more than 20 times every minute.

But for people suffering from the eye disease trachoma, each blink can be agony. With advanced trachoma, every blink brings them closer to blindness, until eventually they lose their sight completely.

Our BLINK interactive photography exhibition took place in London in October 2019 to raise awareness of Sightsavers’ work to eliminate blinding trachoma.

As visitors viewed the digital photos in the exhibition, every blink they made caused the images to change, leaving the photos permanently altered. The results were unpredictable and unknown: an artistic interpretation of the vision loss that trachoma can cause.

Try our photo simulator below for an idea of how the images looked as they degraded during the exhibition.
