Crystalline Lens Information
The Crystalline Lens is one of the most important structures in the eye that help refract light aside from the Cornea. It is located on top of the iris but behind the Vitreous humor. The transparent lens helps light enter into the Retina in a more even matter and helps give you a sense of depth. It changes into various shapes to help process different elements that are several distances apart. This movement is quite similar to that of a camera lens trying to focus. When the lens starts to change or adjust, this action is called an accommodation. The ciliary body is a circle of tissue fiber surrounding the lens. In the ciliary body there are small fibers called zonules that help keep the crystalline lens inside the eye. There are also muscle fibers labeled as ciliary muscles. These muscles help contain the shape of the lens and are typically located behind the iris. The ciliary body needs to contract from time to time and when this happens, the zonules are forced to relax. When this occurs, the lens becomes thicker which makes the eye focus on nearer objects. The opposite occurs when the ciliary body needs the eye to see farther objects. The ciliary body relaxes and the zonules are contracted whenever the eye is observing far objects. This forces the crystalline lens to become thinner. This entire action is simply referred to as the accommodation of the eye. When people get older, the flexibility and elasticity of these ciliary body and muscles start to weaken. When the lens can not safely thicken properly, this causes people to have extreme difficultly trying to see objects up close. The same applies to when the crystalline lens cannot become thinner. It is more common for people unable to thicken the crystalline lens than it is to thin. It is very hard to prevent these fibers from weakening as well as trying to strengthen them. You can sort of delay the process by trying to avoid straining these fibers. For example, staring at the computer screen for long periods of time can cause your eyes to weaken.
You want to look away from the screen every 30 minutes. Start to look someplace where you eyes can use its muscles to contract and focus on farther distances. Staring out a window will help achieve this goal or trying to read a message on a poster all the way across the room will greatly help Protect Your Eyesight. Diet can have a big affect on eyesight. Eating foods that are rich in vitamin A can also help delay the deterioration process. Nothing beats a healthy diet with the right balance of Vitamins and Minerals when it comes to preventing an Eyesight Problem. For those who have already lost the accommodation, then Laser Eye Surgery is a recommended option to help regain the eye's sight. The laser can sometimes cause complications so it is always necessary to talk to a Eye Care Professional or Eye Care Specialist about any post-operation side effects. However, Prescription Glasses or Contract Lenses are now capable of helping those who suffer from Myopia also known as Nearsightedness or short sightedness or Hyperopia also known as "farsightedness" or "long-sightedness" without causing any complications or permanent eye distortion.
