WebIn refractive disorders, light rays entering the eye are not focused on the retina, causing blurred vision. The shape of the eye or cornea or age-related stiffness of the lens may decrease the focusing power of the eye. Objects may appear blurry when far away, near, or both. An ophthalmologist or optometrist determines how best to correct vision. http://www.scienceprimer.com/refraction-lenses

WebSep 12, 2024 · Because the index of refraction of the lens is greater than that of air, Snell’s law tells us that the ray is bent toward the perpendicular to the interface as it enters the lens. Likewise, when the ray exits the lens, it is bent away from the perpendicular. The same reasoning applies to the diverging lenses, as shown in Figure 2.5.1b.
