The image formed by a magnifying lens was ray diagrammed and shown to be a virtual, upright larger image when the object distance is less than the focal length of the lens. The anatomy of the eye was shown from diagrams, stressing the parts involved in the refraction of the light, those parts being the cornea and the lens. The area of the eye containing the light receptors , the retina, also being where the refracted rays of light converge to in a normal vision eye. The image seen is inverted (minus), real and smaller than the object. Farsightedness and nearsightedness were explained in relation to where the refracted light rays converge, and why near vision or far vision is blurry. The correction using a convex lens or concave lens was drawn to indicate the refraction correction done to allow convergence to the focal point on the retina.
