E-YES is a game-based aid to correct amblyopia (reduced vision caused by abnormal development) through exploration and training. Various modular combinations encourage children with amblyopia to perform zoom, eye-muscle, and color-discrimination exercises. The lens on both sides of the telescope work with AR transparencies for children to imagine and explore. The lens in the eye and the ciliary muscle are exercised when the eye switches between near and far objects. E-YES is also a vision detector. Parents can use the vision test panel and guide children to rotate the module. Regular testing tracks changes in children’s vision and detects problems for early treatment.
