It is helpful to do eye exercise regularly

Doing exercise is regarded as the healthiest way to keep fit. Now, a latest study shows that doing exercise is good not only for the human body but also for the eye. For example, the same exercise can keep the cardiovascular fit as well as reduce the probability of macular degeneration and cataracts.

It is reported that a lower risk of age-related macular degeneration comes along with a higher level of HDL cholesterol and cataracts may likely to occur owing to the high level of C-reactive protein caused by inflammation. So it is important to increase HDL and reduce C-reactive protein to keep your eye health.

Regular exercise including focus and rotation exercises are very good methods to strengthen the muscles surrounding the eyes, and the muscle relaxing is a helpful action for good vision.

I will introduce a focus exercise which is called string and bead exercise. First of all, you need to take your focus and eyesight off from your work. Then get a 6’ string and 10 colored beads with holes prepared. Put the beads through the string every 6’’ interval. Tie a knot at each end of the bead and then use a tack to hold it to the wall at your eye level. Hold the other end of the string on your nose. After that, you can do your eye exercise. Focus on the bead nearest to the wall first, then the next bead, one at a time. Practice until you can tell one bead each at one time exactly. That is to say, your eyes are fully exercised.

Another rotation exercise is very easy but quite effective. You can do like this, looking as far as you can to the left, right, up and down several times. It is better if your surroundings are covered with green because the color of green is good for your eyesight.

Our eyes are made up of tiny internal and external muscles, and these muscles help to move the eyes, help to focus and control the shape of eyes. Relaxing is a key factor to maintain good eyesight, so please do not always focus on one thing at a long time and do eye exercise regularly.

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.

Laser Eye Surgery –The Most Popular Choice among Young People

Myopia is a big threat to young adults. Some are congenital, and some are acquired after birth. Nowadays, many treatments are put to use to correct their eyesight, such as eyeglasses, contact lenses and laser eye surgery. A plenty of young adults aged 20 to 25 prefer laser eye surgery to other prescriptions. Now that the cost of glasses or contacts is as much as a surgical procedure, the advantage of laser eye surgery is very obvious. The expense is not very much and it can solve the eye problem only by one surgery. Therefore a greater number of young adults choose to laser eye surgery to enhance their eyesight.

But does everyone can be treated by this method? The answer is absolutely no. Ophthalmologist suggest that young adults wait for at least two years after their eyesight is steady, as nearsightedness changes a lot in youth and can be steady at around 30.

After all, criterion above is not very clear and sometimes can be subjective. Whether to operate or not is still determined by the pre-op examinations. Only those who pass the exam have a good prognosis on operation.

If nearsightedness reduces the quality of one’s life, people with age-related eye problems suffer more. More than 200, 00 people in U.K. are blind due to old age. So ophthalmologists rack their brains to develop a technique to cure this disease. A professor at King’s College named John Marshall is doing a research about how to delay age-related macular degeneration (AMD), and acquires primary effect.

Now here I will introduce the principle briefly. Behind the retina, there’s a thin membrane in which stays a lot of waste. John Marshall stimulates enzymes to clear the waste away so that the function of eye can get its breath again. The result of trial in clinical is delightful. But it’s not enough, and more efforts must be made to improve the technique. Marshall has a dream that the treatment will be put to use in clinics in the next two to five years.

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.

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.

Vision benefits from lutein

With the wide selection of lutein products, some people become skeptical about the effectiveness of these products in various forms. Some sellers make promising claims about their lutein products, but people with poor vision may wonder whether lutein will actually improve vision.

In fact, lutein products can only help patients with bad vision, which is exactly caused by a lutein deficiency. Lutein in the eyes can protect eye tissue from the damage caused by free radicals, which are highly reactive atoms. These free radicals in the eye act on other healthy atoms and damage them, because they require a supply of free electrons. Lutein can effectively fight against these radicals.

In either dry or wet form, age-related macular degeneration is the most common result of these reactive radicals, especially in elderly individuals. And lutein has been found to reverse macular degeneration by combating these radicals and thus improve overall eyesight.

Accounting for 80% of vision defects, dry form of AMD is usually caused by abnormal growth of blood vessels below the retina, which in turn results from reactive chemicals in the tissue. Fortunately, lutein supplements have proven to reverse this condition a lot.

In fact, lutein acts like a neutralizing agent and prevents harmful light rays from damaging the tissue in the macula, which is situated in the center of the retina. As a result, a deficiency of lutein can lead to eye tissue damage.

Lutein is actually only one of the 600 carotenoids in the nature and it is the only one present in the macula of the eye. This lucky carotenoid is available from all the green leafy vegetables consumed by ordinary people every day. A healthy way is to take lutein by eating a nutritious meal every day, including lots of fruits and vegetables.

However, some people have no time to maintain such a balanced diet but they also want to get enough lutein every day. Nutritional supplements are a good choice for those people. It is important to strictly follow the doctor’s instructions on the dosage of these supplements and the way they are administered.
