Asda will become the first supermarket in the UK to offer NHS diabetic eye screening in its stores as part of a partnership with InHealth.
The service is now available in 16 stores and is open Monday to Friday with some also offering Saturday clinics. It is hoped the service will be available in 14 more stores in the coming months.
People diagnosed with diabetes have an increased risk of sight loss. During the appointment, digital images are taken of the back of the eyes (retina), which are then assessed for certain sight-threatening conditions.
