In fact, macular degeneration is caused by the insufficiency of lutein. So many people wonder how much to intake such substance each day is ideal. Here is some information about this question.

Lutein is a very strong antioxidant that usually exits in many foods, as fruits, vegetables, and egg, etc. But sometimes, it is impossible to intake sufficient amount of lutein by eating some foods.

Why is lutein crucial for the health of our eyes? The answer is when people get old; the lutein in their eyes will diminish. And this process is called macular degeneration which will gradually result in complete blindness. Such disease can cause great pressure onto these old people.

In fact, there is a method that can assure sufficient dosage of lutein, in addition to foods. That is to take some supplements that can be gained in the market. One can choose these supplements of any types as he needs. Such as, multi supplements can provide more minerals and vitamins, not lutein only.

Even in the developing world – in Gambia, Malawi and Nepal, where it was once endemic – trachoma and trichiasis (the eye-scraping stage) have all but disappeared. Ghana, Mexico, Saudi Arabia, Iran, Morocco and Oman all now report the disease eliminated. In Australia’s chattering fringes it is also unknown.

But in Katherine, almost a quarter of the children aged five to 15 test positive to trachoma. Without treatment, they’ll go blind. The official incidence in this country is 20,000 among children alone, and that’s just the ones we know about. In more remote areas, cases are often simply unrecorded.

How can this be? How in a nation where the rich and their physicians habitually rort the system to cheat Medicare out of exorbitant cosmetic procedures, in the very nation that produced and reveres Fred Hollows, can avoidable blindness still be rife? Why does the simple fact of it not embarrass us to the point of excruciation, as if it were our eyeballs being grated?

Well, perhaps it does. Perhaps we’re so embarrassed we can’t think about it. So embarrassed we’re happy for the Federal Government to toss yet another $58.3 million at the problem, as it did in February, and hope it’ll go away.

This is a strategy you might call voluntary avoidable blindness. It is abetted by our extraordinarily vivid concept of the continent as a vast, vacant interior ringed (or perhaps girt) by a fertile, febrile megalopolitan fringe where most of us live, deafened by our own frantic chatter.

But it’s a strategy that is unlikely to work. For it isn’t just trachoma, or even just health. It’s housing, hygiene, violence, infant mortality, substance abuse, sexual abuse, education, employment, home ownership, life expectancy, wealth and diet. Across all the parameters, even according to the official Council of Australian Governments report Overcoming Indigenous Disadvantage: Key Indicators 2009, things indigenous are stagnating or getting worse.
