In this Class 10 Science topic from “The Human Eye and the Colourful World,” students learn how the human eye is organised and how it enables vision. The topic explains the roles of the cornea, iris, pupil, eye lens, ciliary muscles, retina and optic nerve. It also describes how light is focused to form an image on the retina and how the lens changes its shape for viewing objects at different distances, introducing the idea of accommodation.
