Natural Vision
Normal cornea (Black of the eye) of a young person’s eye has positive spherical aberration (inability to focus light originating from a single point to a single point on the retina, which is like a film in a camera). This positive spherical aberration of cornea is because of high refractive power necessary in a compact design. However the ingenuity in nature has provided a lens inside the human eye which has a negative spherical aberration, effectively neutralizing the positive spherical aberration of the cornea and bringing light to a fine focus. This is all true in young person aged about 20 years. As the person ages the natural lens in his eye slowly looses its negative spherical aberration and becomes totally ineffective in neutralizing the natural positive spherical aberration of cornea resulting in degradation of visual quality like contrast sensitivity (ability to differentiate myriad shades in dim light) by the time a person reaches 50 years of age. So there is degradation of quality of vision long before cataract sets in due to age. Off course once cataract sets in even quantity of vision is affected, that is the time a patient seeks medical help, which is cataract surgery (removal of diseased natural lens) and implantation of an artificial lens called Intra Ocular Lens (IOL).
