For the accommodation quality, thanks to some special fibers, it is the one that completes the most important paper because it is the one that decides the focus of the proximate objects.

The lawsuits that can give place to the cataract are multiple. Among them hereditary factors that would determine in the mature or senile age their formation fit. On the other hand, genetic and embryological factors exist, and already in the maternal cloister he/she can the petty one to lose temper, with the following appearance of a congenital cataract that will show in the youth in occasions.

But, there are also general illnesses that can end up manifesting this illness: the diabetes, the intoxications (be due to the naphthalene, to the thallium or the rye ergot), and certain medicinal preparations that are used to cure the obesity and that they contain dinitrofenoles.

At the beginning, it still fits some change in the corrective glasses, but as the cataract, this measure evolves it is useless, the patient loses vision and the best thing is an intervention for the expert.
