WebThe human eye forms the image of an object at its retina. The lens system of the human eye forms an image on a light-sensitive screen called the retina. Light enters the eye … WebIn the eye, the image is formed on the retina by successive refractions at the cornea, the aqueous humor, the lens and the vitreous humor. Electrical signals then travel along the optic nerve to the brain to be interpreted. In good light, the yellow spot is most sensitive to detail and the image is automatically formed there.
Web7 apr. 2024 · The human eye is more or less like a photographic camera. The eye's lens system forms an image of an object on a light-sensitive screen. The eyeball is almost spherical, having a diameter of about 23 cm. Two photoreceptor cells, viz., the rods and cones are present in the retina.
