Eye Supplements In Addition To Vitamin A

We all take our eyes and sight for granted, and that's ok cause we are born with them, but we only pay attention to them when some illness or trauma occurs. Sometimes it can be too late as our whole life is affected. There are many methods to take care of our vision, one of the prior importance is nutrition.

Of course we cannot control all the factors that involves the eye's health, but there also are a lot of them that we can prevent. Natural vision problems are caused by age, smoking, sunlight, obesity as well as the intake of many medications. The age related worsening (the most popular) can be delayed by means of nutrition.

It was proven that antioxidants from certain foods have an especially healthful effect on our eyes. Unfortunately far not everyone eats enough fresh produce - either because of the busy style of life, or just can't afford it.

Nowadays its very easy to find all the vitamins and supplements on the market, among them the A, C and E vitamins (antioxidants) have an influence on the eye health.

Vitamin A can be found in meals like eggs, liver, milk, carrot. It is involved in the formation and maintenance of healthy skin, hair and helps us to see in dim light, preventing night blindness for pregnant women.
Our eyes deteriorate without adequate supplies of vitamin C. An indication of its importance is the fact that the concentration of vitamin C in the vitreous humor (the clear liqud in the eyeball) is about twenty-five times our serum level (the level in our blood), the retina 100 times.
The antioxidant qualities of vitamin C help prevent crystallization and accumulation of foreign molecules that result in the blurred vision of cataracts.

People with lower levels of vitamin E in their blood have a higher risk of cataracts and macular degeneration.

Not less important for the vision are the beta carotene, selenium, cupric and zinc oxide, lutein. Smokers should take care to take enough luteine as it is important to the retina.

Eye sight vitamins can be bought without a prescription unless it is a high dosage for certain people who have AMD and require an extra dosage. Over the counter vitamins are usually not expensive and provide most or all of the vitamins and nutrients listed on our eye nutrition page. Normally dosages range from 1 to 4 pills a day but these will vary with the amounts of vitamins and minerals in each pill. It is also good to note that although these vitamins and minerals are good for us, a moderate amount is all we need because taking too much of them can be dangerous.
