Proper diet for better eye health (1)

In two previous articles I stated some of the risk concerning the health of our eyes. There are a whole lot of them. Some are not treatable, with some we have to deal with every day (like TV or computer use) but some are diet related and this is one aspect that we can manage and should be pretty careful. It is important to know that when we feel  our eyes extra tired we can help our body with some nutritional supplements or proper food. I saw a documentary the other day on TV about intraocular lenses and believe me that operation is not one you want to take…
                Besides the ocular gymnastics I told you before vitamins and minerals are also very helpful in eye health.  We all know that carrots are good for our eyes but in the following I’ll point out some of the substances that carrots contain and what other types of food we should consider regarding eye health.
Vitamin A is directly involved in the eyeball health and in visual field. Some of the signs that you lack vitamin A are: the very slow adaptivity to dim light and the dryness of the cornea. In some of the acute forms, the lack of vitamin A can cause ulcerations of the eye and complete damage of the lens. The primary vitamin A sources are: butter, yolk, liver and fish oil.
Vitamin B2 (also known as riboflavin) is vital to the mechanisms that maintain the eye’s proper function. The low B2 levels determine weeping, itching, burning, eyelids gluing together by some white secretion products and can lead to conjunctivitis. You can get rid of all those symptoms by providing your body with more vitamin B from: liver, kidney, milk, yeast, dairy products, rice, oats, wheat bran and almost all vegetables.
Vitamin B6 is found in all the products that contain B2 vitamin. Vitamin B6 is important in adjusting the intraocular pressure and especially glaucoma.
                Inositol is a component of the vitamin B complex and it manages the structural and functional equilibrium of the eye. Citruses contain a high dose of Inositol. You can also find it in: fruits, nuts, seeds, milk, meat and yeast.
It’s very important to know that the administration over a long period of time of one of those B vitamins can lead to lack of all the other. Moreover, a high vitamin B2 dose can lead to sun exposure sensitivity. So it’s recommended that B vitamins to be administrated as complexes.
