Presents the development of an interned lesson in biology, physics and mathematics on the topic: Eye and vision. The lesson was compiled using the resources of the «Mobile Electronic Education» company. At the beginning of the lesson, it was proposed to compare the human eye and the camera, then, as a result of group work, to analyze the causes of visual impairment. In the course of work in a group, students explain what myopia and hyperopia are, how an image is formed in this case. In what way (with which lens) this visual defect can be corrected. It is mathematically confirmed that the power of a lens depends on the focal length (image versus distance). At the end, they answer the key question of the lesson: Which camera is the eye more like: film or digital? Why?
