The aged-related macular degeneration or AMD for short is the main condition in this piece. AMD make a vision loss in the central retina. The reasons cause AMD are complex, but some reasons can be certain that eyes expose in the UV light for long time can make this problem. And a change in the concentration of the macular pigment that compound lutein and zeaxanthin are also believed to make AMD happen.

We can not stop getting old so that our sights are inevitably getting worse, but we can take some measures to delay or minimize the onset of AMD, some tips are as follows: try to manage your blood and avoid getting hypertension; control the cholesterol in a low level; avoid over weighted; do not have too much fat; and do not smoke. The smokers get the risk of AMD higher by two or three times than the normal people.

What is the most important, the more you intake of lutein, the less risk you take AMD, because its cousin compound zeaxanthin will help mitigate AMD. Enough macular pigment compounds are important in eyes health. People can get lutein from the foods such as Brussels sprouts, swiss chard, garden peas, corn, zucchini, broccoli, romaine lettuce, collard greens, turnip greens and kale.

When people get intake some kind of lutein enriched food that whether they get the proper amount of the nutrients is unknown, because it is a big molecule and it dissolves in organic solvents. So if people want to get recommended amount of lutein, they had better drink some kind of oil to help the lutein to get absorbed.

Another way to get proper lutein is to get lutein enriched multi-vitamins. People can easily get the quantity of the recommended nutrient. What is more, some good ones also comes with zeaxanthin which can make lutein have greater effectiveness. Also, they are more convenient.

Some good multi-vitamins also contain some other ingredients; some kind of ones may have about 100 ingredients. Also, accord to different requirements they can be made in different types. For instance, they can be tailored to respectively suit men and women. And good multi-vitamins also include some other good things.

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.

Diabetes is always accompanied by high sugar levels, which may damage the blood vessels of the body, especially those in the eyes. Studies have found that excess amounts of blood sugar caused by diabetes can significantly increase the risk of several eye diseases, including cataracts, blood leakage in the retina, macular edema, macular degeneration, and glaucoma as well as eye infections. Associated with so many possible diseases, diabetes has become a top cause of blindness among US citizens.

Natural aging is inevitable in everyone. Vision loss at different degrees is quite common among old people, especially in those above 50. Vision loss caused by natural aging is always gradual and not noticeable. Yet there are still other health conditions that indirectly or directly affect eyesight in older individuals. Those factors include uncontrolled diabetes, high blood pressure, kidney disease, cataracts, AMD, retinal tears and detachment, glaucoma, diabetic retinopathy as well as presbyopia.

There is a great population of smokers in the world. Unfortunately, most people are not aware of the deleterious effects of smoking on the eyes. Smoking has been thought to increase the risk of macular degeneration and cataracts. This bad habit influences eye health by affecting oxygen level in the ocular tissues. Smoking makes a smoker’s heart to work harder and raise blood pressure, which becomes less efficient in delivering sufficient oxygen to the eyes.

High blood pressure in the eyes can lead to small leaks and clots. Blood leakage in surrounding eye tissues usually affects focus ability. And clots in the eye consume precious oxygen and even cause vision loss. Contributors of high blood pressure include heart disease, diabetes, and unresolved renal disease.

Nutrition also plays an important role in maintaining good eye health. People should regularly consume beneficial nutrients such as anti-oxidants including vitamin A, C and E as well as healthy fats such as omega-3 acids. A lifelong unhealthy diet can speed up aging process.

Lutein is one of the carotenoids produced by pigment in various fruits, vegetables as well as other foods. In addition, lutein is responsible for maintaining the orange color of carrots and squash. When it comes to human body, lutein is believed to prevent conditions including cataracts and age-related macular degeneration.

Lutein performs as an antioxidant in the body, which can remove free radicals that are caused by smoking, air pollution as well as other environmental irritants. The accumulation of toxins in the body can lead to quite harmful diseases such as asthma, arthritis and even some forms of cancer.

Lutein as well as other antioxidants is responsible for removing these harmful radicals from the body. These antioxidants can improve overall health and benefit the function of each system, including respiration, blood circulation and neurotransmission. A metaphor can be given to the oil in an engine.

What’s more important, lutein has special ability to protect the eyes from age-related wear and tear. In particular, lutein can prevent UV rays from damaging the retinas and lenses, which in turn reduces the risks of cataracts formation and age-related macular degeneration.

There are many sources of lutein, including green and orange vegetables and fruits such as spinach, kale, broccoli, carrots and corn. Egg yolks also contain plentiful lutein. Individuals should consume adequate amount of lutein every day, which can be attained from either a well-balanced diet or comprehensive supplements.

Currently, supplements from many shops have become a good alternative to a health diet. Taking supplements can be quite easy and complete. With the healing properties of lutein, ordinary people should give the nutrient enough attention.

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 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.

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.

These supplements protect you from degenerative eye diseases such as macular degeneration and cataracts. The Age-Related Eye Disease Study (AREDS) investigated the natural history and risk factors of macular degeneration and cataracts and evaluated the effect of high doses of antioxidants zinc on the two diseases’ progression in the 1990s. AREDS recommended a formula that can significantly reduce the risk of advanced macular degeneration. The formula contains Vitamin C, E and A, Zinc and copper. AREDS also found that antioxidant eye vitamins can decrease the risk of developing cataracts. A follow-up study named AREDS2 aim at evaluating the effects of other nutrients such as lutein, zeaxanthin and omega-3 fatty acids.

In detail, vision multivitamins should contain certain ingredients. These elements are essential in preventing the deterioration of degenerative eye diseases. Vitamins A helps maintain night vision and heal wounds. Vitamin B complex including B1, B2, B3, B5, B6, and B12 helps decrease chronic inflammation and prevent macular degeneration as well as treat uveitis. Vitamin C and E are also included by the AREDS formula. Lutein and zeaxanthin may also play a role in reducing macular degeneration and cataracts. While phytochemical antioxidants protect eyes from oxidative stress, omega-3 essential fatty acids have been proved to lower the incidence of developing dry eye.

Among various multivitamins solutions, popular brands such as ICaps, Ocuvite PreserVision, Oculaire and MacuTrition are more convincing. Some tips are important when you choose multivitamins. You should check the expiration date and the bottle seal. Doses are also critical that you must strictly follow the dosage instructions on the bottle. Supplements that contain filters such as dairy products, corn and wheat are not suitable for people with allergies. High bioavailability enables your body to absorb nutrients more easily. And capsules are also easier for absorption than hard tablets.

You should also be aware of safety issues while taking eye supplements. Pregnant and nursing individuals need additional care.

There are generally two types: dry AMD and wet AMD, the former of which accounts for about 85-90 percent. Obvious symptoms of dry AMD include yellowish spots from deposits or debris from deteriorating tissue around the macula. Both macular tissue aging and thinning and pigment depositing can lead to dry AMD. Studies show that vitamin A, C and E may help prevent or slow progression of dry AMD. Dry AMD patients are also advised to wear sunglasses when outdoors. People with wet AMD have more severe problems: new blood vessels grow beneath the retina and leak blood and fluid, which damage light-sensitive retinal cells. Wet AMD is caused by the body’s misguided attempt to supply more nutrients and oxygen to the retina, which instead causes scarring and potential vision loss. Occult wet AMD has light blood leakage and less vision loss danger, while classic wet AMD has clear scarring and more vision loss danger.

If you have AMD, your central vision has shadowy areas. During a retinal exam, the doctor may detect early signs of AMD and then an Amsler grid can be used to measure your central vision. For a further affirmation, your retinal blood vessels surrounding the macula will be examined. Many researches have showed that macular degeneration is mostly caused by aging and eye tissue deterioration. Other confirmed or potential risk factors for AMD include drug side effects, smoking, family ADM history, high blood pressure, lighter eye color, obesity, over-exposure to UV lights, fat diet and so on.

AMD-affected people in their 90 develop vision loss at a possibility that is 15 times of that for people in their 60s. And overweight patients have a risk of advanced ADM that is double of that for people with normal body weight. Gene variants are also related to AMD, which is known as family disease. Smoking is reported to bring higher rates of vision loss on ADM patients. AMD occurs more frequently in whites, so that people with lighter eye color are suspected to suffer AMD at a higher incidence. Toxic drugs such as Aralen and phenothiazine may cause side effects that lead to AMD.

Currently, no outright cure is available for AMD. For dry AMD, FDA has never approved any treatment, although nutritional intervention may slow its progression. Those nutrients include zinc, lutein, zeaxanthin and vitamin A, C, and E. For wet AMD, FDA has approved drugs including Lucentis, Macugen and Visudyne to stop or slow abnormal blood vessel growth.

Since complete recovery from vision loss caused by ADM is impossible, regular Amsler grid tests are useful to detect underlying AMD risk. For people with vision loss, many low vision devices such as magnifying glasses are available.
