VisionCheck is a free application designed to provide education and awareness about eye health, particularly for users with diabetes, at home or on the go. Users answer questions and the educational information that appears is based on the choices they select. The application includes three vision tests: The Tumbling “E” Test, The Tumbling Shape Test, and The Amsler Grid Test. The causes, symptoms, and effects of three common diabetic eye diseases, such as Glaucoma, Cataracts and Diabetic Retinopathy, are also provided by VisionCheck. Users are encouraged to contact their eye care professional if they have questions or concerns. This application is not intended to provide a diagnosis and all users should visit their eye doctor for a full examina­tion.
