Clouding of the lens which is present inside the eyes will decrease the vision and this is called as Cataract. This is one of the causes of the Blindness and this can be treated through the surgery. Loss of vision is mainly due to the opacification of the lens does not allow the light to pass through and this is being focused on the back of the eye. This disease is mainly caused due to the biological aging but there are also other reasons. Over time, yellow brown pigment which is found within the lens and this also the causes the trouble in the normal architecture of the lens fiber. This may lead to the reduction of the transmission of light and may also cause the vision problems. People those who are having the problem of cataract will have problems in differentiating the colors and changes in contrast. It will also create problems in reading, driving, recognizing the faces. The major problem is coping with the glare from the bright light.
Depending on the types of cataract the symptoms will vary. Sometimes they will overlap also. People those who are suffering from the nuclear Sclerotic often suffer from the reduction of vision. Some people will be suffering from the Posterior Supcapsular cataract then they will be facing the problems with the glare vision. If there is no any other disease with the person but they are suffering from the severe cataract then Visual acuity test is taken. The surgery mainly depends on the patient's particular functional and also the visual needs and also contains the other risk factors. They may also vary.
There are many causes by which this disease will occur. They are Age, Trauma, Radiation, and Genetics and there are other also causes.
Age: Most common cause of this cataract is Age. Due to diabetes and hypertension lens proteins are denature and they also reduced over the period of time.Even the environmental factors such as toxins, radiation, UV with more effect will also one of the causes. They are mainly caused due to the worse effect of loss of the protective and restorative mechanisms which is mainly due to the difference in the gene expression and chemical process which is taking place within the eye.
Trauma: Blunt Trauma mainly causes the swelling, thickening and whitening of the lens fibers. Swelling normally resolves in time and the white color may remain. In case of the severe Blunt Trauma with penetrate the eye and the eye capsule may be changed. Thus this allows the all the other parts of the eye and they enter into the lens which may leads to the swelling and also whitening.
Radiation: Ultraviolent light which causes this problem of Cataract. So some issues have shown that the wearing of Sunglasses in the early stage will prevent this in problem. Most of the UV rays from are filtered by the atmosphere but with the Airline Pilots are the people those who are suffering from this problem.
Genetics: Strong Genetics component which is the development of cataract is obtained through the proper maintenance and protection of the eye.
