How to Maintain the Health of Our Eyes?

Our eyes are vulnerable to some diseases as we age. When we are over forty, we may suffer from presbyopia; when we are over fifty, we may suffer from Age-related Macular Degeneration (AMD), which can always lead to irreversible blindness. Here we are going to introduce something about AMD and some methods of prevention. The mechanism of AMD is the blood vessels in our eyes may become very fragile and the blood flow into our eye tissues. The most direct result is blurriness as a result of macular degeneration. However, as the conditions get even worse, our eyes will be in complete blindness.

That’s to say; once the macular is damaged or thinned, our vision will be influenced. The reason is our retinas are protected by the macular pigment from coming light. The thinner our macular pigment is, the worse our eyes are.

In fact, some substances play very important role in the protection of our eyes. For example, Lutein is a very effective antioxidant substance than are very useful in the protection of macula.

The scientists have not found such a method currently that can be employed in the cure of Macula Degeneration. But prevention is much important than treatment. Some very common methods can be used for the prevention of such diseases. Following are they.

We should first know what AMD is and what the cause of it is. Some bad habits can reduce the density of macula pigment. Such as, smoking and drinking alcohol can be very irritating for the macula; working under too bright light, as the sun and computer, can also reduce the density of the pigment. As mentioned above that lutein is very effective antioxidant substance which can help slow the process of macula degeneration. In this sense, it is very essential for us to intake foods that are abundant with lutein.

In fact, other materials can also help to slow the process of AMD. Thus, we should intake more other vitamins and mineral, while ingesting lutein.

Some eye doctors recommend that there are four substances that are vital for the health of our eyes.

The first one is, no doubt, lutein that is a kind of very effective antioxidant substance. It is very nice for us to use some lutein pills that are extracted from marigold plant. It is true that these pills are expensive, but effective.

The matter of fragility in the blood vessels can also be prevented by taking Bilberry in which flavanoids and anthocyanin are contained. Our eye muscles can be benefited a lot from this substance. Taking such pills everyday is essential.

The problem of bad elasticity in the blood vessels can also be avoided by intaking some grape seeds extract. If our blood vessels lose their elasticity, we will suffer a lot. These pills can help prompt the circulation of our blood. Take some everyday.

The commonest Vitamin C is still very important, for it is essential for the synthesis of some tissues. Like lutein, it is also an antioxidant substance. Take some Vitamins C pills everyday.

How To Fight Age-Related Macular Degeneration

There are millions of Americans all over the country suffering from the effects of Age-Related Macular Degeneration (ARMD). While treatment for Age-Related Macular Degeneration is limited, there are many different options for people to slow the progress of the degenerative eye disease.

What is Age-Related Macular Degeneration?

Age-Related Macular Degeneration is a serious eye disease that affects the retina, distorting and deteriorating your ability to see crisp, clear objects. For people over the age of 50, the arteries that run to the retina can harden, preventing blood from reaching the cells vital for your vision.

When the arteries simply harden and stop providing the retina with the blood it need to function, it is referred to as “dry” macular degeneration. For some people, the eye disease doesn’t stop there. The body can attempt to form new blood vessels to supply the retina with the blood it needs; unfortunately this tissue can damage the retina you can lose the majority of your vision.

If you live in the Charlotte, North Carolina area and would like to prevent the onset of Age-Related Macular Degeneration, the best thing you can do is schedule a consultation with an experienced optometrist or ophthalmologist.

In addition to scheduling your Age-Related Macular Degeneration consultation, there are a few different safety measures you can take during everyday life to help avoid developing ARMD:

  • Stop Smoking – Perhaps the biggest step you can take, smoking not only puts you at risk for many other health problems, but smokers are four times more likely to develop Age-Related Macular Degeneration
  • Maintain a Healthy Diet – A diet rich in leafy, green foods can help prevent Age-Related Macular Degeneration because the carotenoids within the vegetables decrease the risk of developing or advancing ARMD
  • Eat More Fish – While this may coincide with the second suggestions, studies have shown that people who eat   more than two servings of fish every week are 45% less likely to develop ARMD than people who rarely eat fish
  • Exercise Regularly – Maintaining a regular exercise program can help you keep your cardiovascular system healthy, making you less likely to develop the hard arteries that lead to ARMD
  • Wear Sunglasses – Overexposure to the sun is directly linked to developing Age-Related Macular Degeneration, which is why is it important to wear sunglasses when going outside or participating in outdoor activities

If you’ve already taken some of these precautions, the best thing you can do now is to schedule regular eye exams.

MP density and AMD

Found in the macula, the macular pigment (MP) consists of two pigments or carotenoids: lutein and zeaxanthin. MP is most dense in the center of the macula named fovea. Moreover, these two pigments have different concentration is different parts of the eye. Lutein makes up 67% or greater of the MP in the peripheral retina. But in the central macula, zeaxanthin is the majority that it accounts for up to 75% of the MP.

MP in the eyes can protect them from harmful effects or free radicals caused by excessive exposure to UV rays and blue light. In detail, the two pigments of MP can help prevent age-related macular degeneration. In general, there are two ways to get enough lutein and zeaxanthin. A balanced diet with plenty of green vegetables and fruits as well as dietary supplements of the two nutrients can both offer enough MP.

As supplements are one of the main sources of MP, there are many studies focusing on these supplements as well as their effects. One study named enhancement of macular pigment density by oral lutein supplement (EMPOLS) conducted by researchers in Berne, Switzerland evaluates the relation between MP density and intake of supplements containing lutein. Participants of this study consume 10mg of lutein supplement product labeled VitaluxPlus on a daily basis.

Another observation study named the role of macular pigment in patients with age-related macular degeneration is also being carried out in Switzerland. Expected to complete in December 2009, this study has several purposes. First one is to assess how MP density and its distribution are associated with age-related macular degeneration. A second aim is to identify patients with low MP density. The study is still supposed to improve the early diagnosis of patients susceptible to AMD. Since low MP values are high risks of AMD, the observation study will develop a basis for dietary supplementation of lutein and zeaxanthin.

A balanced diet beneficial to eye health should contain many foods. Lutein is one of the critical elements. Many sources are rich in lutein, including corn, eggs, spinach, carrots, cantaloupe, oranges, red and orange peppers, kale, and collard greens and so on. In order to facilitate the absorption of lutein through the digestive tract, it is also necessary to eat some healthy fat in combination with those raw vegetables.

Natural nutrients sources are better

Lutein is one of the carotenoids that are found in many plants and animals.  Other pigments in the same family include zeaxanthin, astaxanthin, lycopene, beta-carotene and alpha-carotene. Although lutein and zeaxanthin are most commonly thought to benefit the eyes, other pigments also have antioxidant activity in the human body.

During the past several years, most eye doctors or nutritionists recommended a single-ingredient lutein supplement. They think this kind of supplement is beneficial to the eyes, because lutein is most highly concentrated in the retina. And some lutein supplement promoters are airing ads on television. But latest studies have shown other results.

It is true that some earlier studies have proved the effectiveness of lutein supplement or the combination of lutein and zeaxanthin. These nutrients alone can reduce the risk of developing age-related macular degeneration. These studies have considerably promoted the prevalence of lutein supplements.

However, a recent study revealed something different. It compared the blood level of various antioxidants in people with and without macular degeneration. Researchers found that people with high levels did not have macular degeneration. The result is that the total blood levels of carotenoids offer proper protection against the disease.

Supplement products on the market are quire disappointing. A shocking fact is that some lutein supplements as well as vitamins are synthetic. These vitamins can be basically plastic. In particular, most commercial lutein products at low prices are synthetic.

As mentioned before, astaxanthin is another less common antioxidant associated with macular degeneration prevention. A wholesaler of natural astaxanthin named ALGA technologies reveals that nearly all commercial astaxanthin is made of petrochemical sources synthetically.

There is no doubt that these synthetic chemicals have no benefit to human body. But many customers are told to take these supplements on a daily basis. They believe that these lutein supplements as well as multi-vitamins are good for their health. In conclusion, natural sources of these nutrients should be chosen.
