Peek is a portable eye examination kit that clips onto a smartphone to allow healthcare workers to easily perform eye exams and screenings. It functions as both an ophthalmoscope and retinal camera to diagnose conditions like cataracts and glaucoma. By making eye exams affordable and accessible anywhere via smartphone, Peek aims to help eliminate the 39 million cases of avoidable blindness worldwide, especially in underserved regions without traditional eye care equipment. The system was created by a team that includes ophthalmologists, engineers, and designers, and has been recognized with awards for its innovative approach to healthcare technology.
