How are images formed in the eye

WebRefractive indices are crucial to image formation using lenses. Table 26.1 shows refractive indices relevant to the eye. The biggest change in the refractive index, and bending of rays, occurs at the cornea rather than the lens. The ray diagram in Figure 26.3 shows image formation by the cornea and lens of the eye. WebImages are formed at locations where any observer is sighting as they view the image of the object through the lens. So if the path of several light rays through a lens is traced, each of these light rays will intersect at a point upon refraction through the lens.
