+ How to restore vision home

Minerals are required as a building material for all organs, including the eyes. In addition, minerals are active participants in all the biochemical processes in our body.
All minerals are divided into two groups: macroelements that are necessary with respect to the body in large quantities, and trace elements required in small doses. Necessary makro_ and minerals must be ingested with food and water, but not always a person is getting enough minerals. To a large extent it depends on the composition of the water and soil of the area of residence. New technologies of growing fruit and vegetables on the special artificial soils, which give a great harvest, the fruits do not provide a sufficient amount of vitamins and minerals.

Vitamins + + eye to improve vision list
By macroelements that are especially important to our eyes, include the following seven elements: sodium, potassium, magnesium, calcium, phosphorus, chlorine and sulfur.

The daily requirement for other macrocells — phosphorus — the same as in calcium and of 1 g per day. If phosphorus is supplied more than calcium, it can lead to weakness and stretching of the sclera, which is directly linked to the development of myopia. The ratio of calcium to phosphorus is close to the ideal (1: 1) in dairy products, as well as in a favorite Russian dish — buckwheat porridge with milk.

Great is the role of calcium in strengthening the sclera, performs a protective function for the eyes and the role of a skeleton. Calcium deficiency due to the weakening of the sclera may contribute to the development of myopia.
The major suppliers of calcium in our body are milk and dairy products, in which the high content of calcium, and is in
easily digestible form. The calcium absorption plays an important role vitamin D, and parathyroid hormone and thyroid.

The first thing to be said of sodium, which ensures proper operation of the cell membrane, regulates the balance between potassium and calcium, prevent excessive outflow of water from the tissues.
1 g of sodium contained in 2.5 g of salt. Our body is closely related exchange of sodium with potassium exchange. So, if you eat a lot of salty foods, it causes the body potassium loss.
For the eyes of sodium is particularly important. An excess is extremely undesirable, especially to the eyes of patients. The fact that an excess of salt increases blood pressure, including vessels in the eye. When expressed in atherosclerotic process vessels elderly eye sometimes «can not withstand» high blood pressure, which can lead to intraocular hemorrhage — or intravitreally to the retina. Such bleeding is significantly impair vision.
People suffering from glaucoma are not recommended salty products (herring, pickled mushrooms, sausages, canned vegetables, salted nuts, chips), as excessive salt intake leads to a delay of intraocular fluid and increased intraocular pressure.
Glaucoma patient enough 3-4 grams of salt a day (by the way, and a healthy person it is expedient to be so limited quantity). This is the amount of salt a person gets from food — bread, sausage, cheese, hamburgers, etc. -. Without additional dosalivaniya.
