Normally clear lens of the eye. In the event of the cataract, the lens becomes opaque as milk glass. Cataracts occur slowly, so vision impaired in various ways according to the level of turbidity of the lens. Cataracts are not contagious from one another eye to eye, but can occur in both eyes simultaneously. Most cataracts occur because of chemical changes in lens proteins that cause the eye lens becomes cloudy. Chemical changes in the protein core of the lens resulting in progressive pigmentation, so that the color around the eyes become yellow or brown, decrease the concentration of glutathione and potassium, sodium and calcium concentrations increase, and the last is the increase in lens hydration. Changes in these conditions can occur due to increasing age or because the process of degeneration.
Cataract is a type of eye damage that causes webbed and myopic lens of the eye. Eye lens becomes cloudy and light can not penetrate. Cataract conditions vary according to level, from a little to the total opacity and prevent the passage of light. In the development of age-related cataract patients can lead to the strengthening of the lens, causing the patient to suffer miopi, yellowing gradually and opacity of the lens to reduce the perception of blue. Cataracts typically progress slowly causing vision loss and potentially blinding if untreated. This condition usually affects both eyes. Cataract is the turbidity that occurs in some or all parts of the eye lens. The cause of cataracts is due to aging, accident, disruption of metabolism due to prolonged illness, congenital diseases or even poisoning.
