DESCRIPTION
In , of adults with diabetes aged 40 years or older, 4.2million (28.5%) people had diabetic retinopathy, damage to the small blood vessels in the retina that may result in loss of vision. Current insulin pumps on the market don’t offer solution to visually impaired users. Asante solution and the Research Center for Persons with Disabilities have join forces to work towards finding a solution to the lack of accesible insulin pumps on the market
