What are the main causes of cataracts?
Cataracts are one of the most commoneye diseases in old age. Studies show that about ½ of the world's population aged 40 or older suffers from blurred vision due to the development of this disease. The fact is that over time, the lens of the eye loses its transparency and elasticity, and therefore develops turbidity.
The causes of cataracts can be different. Experts conventionally divide them into two groups - external and internal. Internal factors include heredity, various chronic diseases (diabetes mellitus for example), improper metabolism in the eye tissues, age-related disorders, and so on. The causes of cataract external are trauma, radiation or radiation exposure.
With age-related cataracts everything is clear - the bodyaging, and changes occur, sometimes not the most pleasant. Much worse is the case with childhood disease. Cataract in children, the reasons for the development of which are studied to this day, are also due to many factors. As a rule, there are two of its types - hereditary or pathological. Most often the disease progresses in those children who suffer from one of these diseases - Low syndrome, homocystinuria, galactosemia, Sjögren's disease, hyperaminoaciduria and others. With heredity, everything is clear - if someone from the family has cataracts, then the risk of the disease is doubled.
The causes of cataracts may be different, butthe development of the disease in one or another confluence of circumstances is always the same. It is worth mentioning the first signs: the deterioration of the vision in the darkness and the blurred vision, sensitivity to bright light, the splitting of objects, the difficulty in reading books with small print or sewing. Perhaps the appearance of small strips or spots in the field of view, the difficulty in selecting glasses and the indistinguishability of the primary colors.If you find yourself showing signs of cataract,immediately consult an ophthalmologist. You will be given a comprehensive examination, based on the results of which the treatment will be carried out. Do not be afraid - all kinds of examinations are absolutely painless and will take at least your personal time, but you can save your eyesight!

There are medicinal preparations that can slow down its development for a while. The only way to treat is surgical intervention. Instead of a clouded lens of the eye, an artificial implant is spinning into the canal, which has all the properties of the original.
