The photo, pictured, shows what people with the condition, which is the leading cause of preventable sight loss in working age adults, have to live with and how it can obscure vision.
Over 291,000 people in Scotland have diabetes and attending regular retinopathy screening is an essential part of their care.
But 42,000 people who are eligible for screening have not taken it up in the last 15 months and are being targeted by the How Do You See Scotland? campaign by Diabetes Scotland and RNIB Scotland.
Campbell Chalmers, director of RNIB Scotland, said: “Retinopathy is the single biggest cause of preventable sight loss among working-age people. That’s why it’s so important that everyone with diabetes attends the eye check-ups that will be part of their care.”
And Jane-Claire Judson, National Director of Diabetes Scotland, said: “Screening is vital to pick up early warning signs of damage to the eye so that people can get the treatment needed to prevent permanent damage.
“We need to understand why people are not attending their screening appointments and what can be done to remove these barriers.”
