Crystalline Lens
 One of the most important structures of the human eye, called the crystalline lens, is situated in between the iris in front and vitreous humor behind. It focuses light onto the retina. A soft material called the cortex surrounds the nucleus, i.e., the innermost part of the lens. A capsular bag encases the lens in itself.  Tiny fibers called zonules in the ciliary body keep the crystalline lens suspended inside the eye. The ciliary body is a ring of tissue encircling the lens. It comprises of involuntary muscle fibers called ciliary muscles. The job of ciliary muscles is to control the shape of the crystalline lens. The ciliary body lies just behind the iris. When the ciliary body contracts, the zonules relax.  As a result, the crystalline lens goes thicker. This enables the eye to focus up at a closer distance. When the eye is looking far, the ciliary body relaxes. As a result, the zonules go contracted. As the zonules contract, the crystalline lens goes thinner. The eye gets focused to look far. Thus the crystalline lens changes its shape according to the distance the eye is trying to look at, and adjusts its focal length for close or distance vision. This is what is called the accommodation of the eye for distant or near vision.  With age comes presbyopia. What happens is that the ciliary body muscle and the crystalline lens gradually go on losing their elasticity; till by the age around 40, they lose enough of it so as not to be able to sufficiently thicken the crystalline lens for near reading. But there is another mechanism in the eye, which is in fact the more natural one and should have been used all through the life, that can replace focusing through the crystalline lens. It is changing the length of the eyeball with the help of voluntary muscles on its surface! And the eye starts focusing well again! Today, LASIK eye surgery is correcting vision by sculpting cornea with the help of a laser and thus distorting the natural eye anatomy for life, although not a single structure of all the parts of the eye has any role at all to play in spoiling the vision in the first place! Vision therapy does the needful without even touching the cornea or any of the parts of the eye in order to affect a change in the vision. Rather it is simply done through changing the physiology of the eye which, by going faulty, turns the real culprit as far as the errors of refraction, namely myopia, hyperopia, presbyopia, and astigmatism are concerned. I invite you to subscribe to my weekly E-zine titled Third Eye-zine. This weekly E-zine publishes rare, revolutionary articles which are of real use in the day-to-day life of a common man, covering topics concerning the effect of third eye opening on health, diseases, personality, performance, efficiency, relationship, sex, mind, creativity, passion, business, management, and energy level of a person; apart from its effect on vision correction. A not-to-be-missed opportunity! Subscribe to it here: I also invite you to subscribe to my Third Eye Blog - no need to provide your e-mail address here.
