This is a disease of the older generation. One that I had not heard of before my father started showing signs of it. Taking ample amounts of omega 3 may prevent it.

It is a progressive disease that affects your center vision. Centre vision is required to be able to read and drive. The people suffering from this disease need to give up driving, and need a special magnifying glass, which lights up in order to read.

The disease can affect one or both the eyes. It is one of the main cause of blindness in the people who are over the age of 60.

People who are aware of this disease, shudder with fright as they approach 60 years of age. As I am searching for help for my father, I am also aware that the disease is hereditary. You need to look for ways to prevent this disease catching up with you in the later stages of life.

Taking omega 3 supplements in the early ages could help to prevent this disease in the old age.

The macula tissue is present in the middle of the retina. The retina is sensitive to light. The retina’s job is to change light or pictures into electrical impulses and send them onto the brain.

Macular degeneration are of two types.

The first one is known as wet macular degeneration. It is caused by the abnormal growth of the blood vessels behind the retina. The blood vessels are very delicate and can possibly let blood or fluids leak out. This makes the macula to rise out of the normal spot at the back of the eye. When this happens, the damage to the macula is rapid.

The blindness that sets in rapidly, is known as as Advanced Macular Degeneration.

You can watch for early symptoms of AMD by using a chart. This chart has intersecting lines on it. It sort of looks like graph paper. There is a dot in the middle of each intersecting line. If these lines appear wavy as you test them with each eye, covering each eye one by one, then you need to see your eye specialist right away.

The second type is dry AMD. The dry type starts when the light sensitive tissues in the macula slowly break down. Your central vision slowly becomes blurred. As the dry AMD worsens, a blurry spot appears in the central vision. With the passage of time condition gets worse, you could loose your sight in the affected eye.

Drusen is the earliest symptom of AMD. Drusen can be diagnosed by the eye doctor in a routine eye examination when they dilate your pupils. They are yellow spots found under the retina. It is normally found in people over 60 years of age. If there is an increase in the number of these yellow spots or their size, it’s a sign of them possibly developing either type of the AMD ending in loosing sight.

Apart from age, the other risk factors for developing AMD are:

Smoking
Obesity
Race
Family history and gender.

Changes in your lifestyle that could make a difference are:

Eating a good diet of green leafy vegetables and fish
Keeping your blood pressure under control
Maintaining a healthy weight
Regular Exercise. And definitely don’t smoke.

Another change in lifestyle, you could adopt could be to add more Omega 3 to your diet. As mentioned above, include fish in your diet. Not everyone enjoys eating fish. There are a variety of ways to get Omega 3 and a good way to know you are getting enough is to take supplements.

My father is almost blind now. I hope that the disease does not progress any further. We have put him on Omega 3 supplements hoping it will stall the disease. Only time will tell. As for others, try to prevent it before it happens to you.

Were you aware the connection between omega 3 and retina health was recently expanded when researchers showed that it could prevent age-related macular degeneration or AMD?  Here’s a little bit about AMD and omega-3s.

AMD is the most common cause of vision loss among the elderly.  Although it does not usually cause complete blindness, central vision is lost.

Losing your central vision is like having something in front of your face all of the time.  But, when you turn your head it follows you.  You cannot look around it.  If you turn your eyes, the blind spot moves with you.  All that you have is your peripheral vision.  You have to learn not to look directly at something, if you want to be able to see it.

The condition makes using a computer, reading or taking care of bills difficult, if not impossible.  Even meal preparation and eating are taxing.  Most people with AMD need assistance to stay in their homes.

The retina is the light-gathering structure that lines the inside of the eye.  The macula is a point on the retina, near the back of the eye.

The retinal lining and the macula specifically are composed of polyunsaturated fatty acids, carotenoids and other compounds.  There’s your first connection between omega 3 and retina health.  Omega-3s are essential polyunsaturated fatty acids.  They must be present in the diet in order for the body to repair organs and tissues.

The typical American diet provides far more omega-6s than 3s.  In some cases, people consume 40 times more 6s than 3s.  While both are essential, this drastic imbalance in intakes sets the stage for inflammation throughout the body.

About 60% of the polyunsaturated fatty acids in the retina are DHAs (Docosahexaenoic acid).  DHA is found only in some kinds of fish, some types of seafood, fish oil and some varieties of seaweed.  If your diet includes none of those things, you are not getting any DHA in your diet.

This is the likely connection between omega 3 and retina disease in the US.  Americans tend to eat more beef, chicken, pork and other meats.  Those provide some omega-3s, but not DHA.

AMD is a degenerative eye disease.  It progresses, because the body does not continue to repair damage done to the macula as it should.  The current theory is that a low intake of essential nutrients is the reason that the body stops its repair work.

In studies concerning omega 3 and retina health, researchers found that DHA supplements slow the degradation and provide some improvement in central vision.  There suggestion is that supplementation may help prevent AMD.

If you would like to take an omega-3 supplement to reduce your risk of AMD, remember to look for fish oil or algae oil.  The flax seed supplements do not contain DHA.

Many other benefits are associated with increased DHA intake.  But, it is important to choose your supplements carefully.  Some are far better than others.

Now that you know a little more about the connection between omega 3 and retina health, you might want to take the time to learn about choosing the best supplements.

Macular degeneration is the symptom where you suddenly lose the principal visual field, and are left with solely fractional vision for the remaining fields. Shockingly enough, those that are over fifty in age are at rising risks of getting this and it’s already one of the most common causes of blindness in States.  Fortuitously, there’s a way which may also help to radically scale back your chance of getting this condition.

When you’ve got not known this previously, then the solution would be taking Omega 3. Undoubtedly, it’s going to assist you tremendously in decreasing the risk of contracting macular degeneration. This is due to the fatty acids in Omega 3 which can only be replenished via consumptions, as our physique merely cannot manufacture them.  At any rate, we can definitely get them from Omega three capsules or meals like Salmon, Hoki or Tuna on a daily basis.

Having stated that,  regular intake of Omega 3 is therefore actually necessary to scale back the chance of macular degeneration. For your information, when this condition strikes, the resulted loss of vision would make it extraordinarily hard to read. In severe instances, it might even be not possible to distinguish things entirely. Therefore, if you’re serious about stopping or lowering the danger of this condition, the best way is to begin the regular intake of Omega three early.

However, it is essential to know that you have to be extremely careful in getting Omega 3 supplements. To be precise, it’s best to only get those which are molecularly distilled because those that haven’t gone through this process shall be full of impurities such as lead and so on. All these toxins must be prevented at all costs as they are harmful to your health. All in all, with careful selection of Omega 3 dietary supplements, they will be good for you.

Loss of vision or Macular Degeneration (MD) is a common problem for senior citizens. It is also known ad Age Related Macular Degeneration (AMD).

It affects the macular of the eye which is the centre of our vision. The results are blurred vision or difficulty reading and the requirement for brighter light when reading. It may have serious life style consequences such as becoming legally blind and unable to drive.

There are two types of vision loss or AMD known as Dry AMD and Wet AMD. Dry AMD often leads to Wet AMD.

Dry AMD generally starts gradually with loss of central vision. Wet AMD can follow Dry AMD but can also occur faster and result in sudden loss of central vision.

There are many factors that affect the likelihood of a person suffering from AMD. These include genetic susceptibility, lifestyle related issues such as diet and smoking, general health including heart health and exposure to excessive sunlight.

The Omega 3 fatty acids known as DHA and EPA have been shown to be beneficial when it comes to visual health. These fatty acids affect the nervous system and the visual system positively. DHA and EPA are essential fatty acids, that is they cannot be produced by the human body and must be contained in the diet.

Dietary items such as dark green leafy vegetables and fish are recommended for good visual health. Eating oily fish such as salmon, tuna and sardines at least twice a week or more is recommended. It has been shown that populations that eat more fish are less likely to develop macular degeneration.

Omega 3 fish oil supplements are an excellent alternative to eating fish if fish are not available or there is a dislike of eating fish. Usually available in easy to take capsules Omega 3 supplements can help to prevent or reduce the effects of vision loss.

Omega 3 fish oil capsules are produced from raw fish oil by a process of micro distillation or stripping which removes impurities and concentrates the Omega 3 fatty acids in the end product. The result is a product that is pure, concentrated and easy to take.

If necessary consult you doctor about Omega 3 fish oil supplements to ensure there is no conflict with other medications.

Vision loss can be devastating but can be prevented or the effects reduced by the use of Omega 3 Fish Oil supplements.

Healthy Vision makes for Happier Life.

Having difficulty seeing lately? Is your vision becoming blurred when you read? Need more light to read by?

More than 10 million Americans are affected by age-related macular degeneration (AMD). AMD is a chronic eye disease. For persons over sixty in the United States it is the leading cause of vision loss.

Macular degeneration (MD) as the name implies is the degeneration of the macula which is the tissue in the part of your retina that is responsible for central vision. The result is blurred vision or a blind spot in the center of your vision. This loss of vision can interfere with reading, driving, or other daily activities. The first indications may be when you need more light to see close-up work.

AMD comes in two forms. About 85% of those affected by AMD have Dry AMD which causes gradual loss of central vision, usually starting in one eye. Severe vision loss from AMD is caused by Wet AMD. About 90% of those affected by severe vision loss have Wet AMD. This often involves results in a sudden loss of central vision. Dry AMD often progresses to Wet AMD.

The following conditions or characteristics are most common in people who are at risk for developing AMD:

Age is the leading cause of severe AMD and vision loss for persons over 60 Women rather than men are more likely to develop AMD. Smoking of Cigarettes has been shown to be related to AMD Genes – macular degeneration in previous generations Cardiovascular disease can lead to macular degeneration High levels of cholesterol can cause MD Persons with light eye color as more prone to MD Long-term exposure to sunlight can cause MD Low levels of antioxidants in your blood

Prevention of AMD
One of the most effective ways of preventing MD is diet.

Dark leafy greens should be included in the diet to lower the risk of AMD. These leafy greens include spinach, kale, collard greens, and watercress.

The inclusion of fish and particularly fish high in Omega 3 fatty acids can have a very beneficial effect on the eye sight and vision. It has been shown in studies that persons who ate more fish were less likely to develop AMD than those who did not eat fish. The Omega fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are two types of omega-3 fatty acids found in fish. It was found that eating fish four or more times per week reduced the risk of developing AMD.

An alternative is the use of Omega 3 fish oil supplements which are high in DHA and EPA. These supplements are manufactured from raw fish oil using a process called micro distillation which produces an end product that is rich in the DHA and EPA Omega fatty acids. The process also removes the contaminants such as mercury. The product is pure, free of pollutants and easy to take.

Adding more fish to your diet is a good option. Using an Omega 3 fish oil supplements is an easy alternative if fish is not freely available or you have less inclination to eat more fish. Talk to your doctor about taking fish oil supplements if you are at risk for AMD. Even if you are not a candidate for AMD you can improve your vision by the use of fish oil supplements.

Healthy Eyes are Happier Eyes.

Have you heard that there are a lot of health benefits that omega 3 offers? Like, the promotion of brain health, prevention of cancer, reduction of risks of cardiovascular diseases, the development of immune function, and its anti-inflammatory properties. However, the most basic, and perhaps the one which you will value the most, is its capability to protect your eyes and keep your precious sense of sight.

Studies delving into the relationship between omega 3 and retina have provided accurate and credible evidence. It was shown that this family of fatty acids is indeed capable of initiating positive effects on eye health.

Degenerative diseases such as retinitis, pigmentosa, and macular degeneration due to age are prevented when omega 3 fish oils protect the retina’s cells. Note that the latter of the three mentioned diseases is the top reason for loss of vision of people beyond the age of 65.

Omega 3 and retina are joined in a very complex way, and this allowed the involvement of the acid in the fight against eye impairments. Degenerative diseases progress when the photoreceptor cells gradually break down and die. This is due to exposure to dangerous levels of sunlight and tension characterized by high oxygen level.

The retina has cells called retinal pigment epithelium (RPE) that bear the omega 3 fatty acids. These acids in turn are what fight the gradual damage of the cells.

Whenever an omega 3 source, like cold water fish, is eaten, omega 3 gets absorbed by the RPE. Omega 3 and retina are obviously best buds in the quest for good eyesight.

Additionally, it was found out in Australian studies done just recently that including fish in meals at least twice a week reduces the likelihood of age-related macular degeneration (AMD) in both early and late stages of life. Then again, higher intake of omega 3 fatty acids decreases the risk of further advanced cases of AMD by a significant 38%.

If you are considering adding a daily fish oil supplement to your diet, be certain and check that the oil was molecularly distilled so the harmful toxins cease to exist. Because as you just read, the key to retina eye health and good vision is making sure you get enough quality fish oil in your diet.

Now you know the benefits of omega 3 and retina eye health. So if you want to keep those eyes and maintain a 20-20 vision, make sure you get your daily, if not weekly, dosage of fish meals. Or, start taking the best fish oil supplement today!

It is a video that we made for Chemistry for Mr. Mach’s class. It is really good. I really like it. Big credit to Justin for making it for us. And also lots of credit to Jeshua Aveno for letting us interview him. Thank you guys.
