How to Diminish Eye Stresses

From any standpoint, our eye problems are caused by stresses. As for the structure of our eyes, they are composed of many muscles that can coordinate our visions. If we now are very stressful in our work and lives, some eye problems will occur in the future. So the solving of these stresses is of vital importance.

Saying is easier than doing. To solve these stresses is very hard. Even as for this matter, some of us think it is possible and practical, but other think it is funny. Nowadays, it is very important for us to learn the way of solving stress, as our daily lives are full of stresses.

Now, let’s begin our process of solving stress. The first is to find out the root of our stresses. If we can not find the root, there is no solution for our stresses. There is always a solution for any problem. For example, if you can not do something in time, just set the time ahead a little. If you encounter traffic jam, try another way.

Generally, stresses come from our daily work. Too much work makes all of us felt very stresses and tired. Now, as for these matters, we should ask other people for help or expound cleanly to our bosses. All work what we do should be within our ability. If they are out of our ability, it will be very tired for us to deal with them.

The way for relaxation is very simple. First, inhale deeply. Then, relax ourselves with eyes closed for some time. Look at objects far way for some minutes in each working hour. Because vision problems will ensue if we have accumulated too much stresses.

Eye makeup unsafe for children

Eye makeup such as mascara, eye shadow and foundation can be a danger to young girls, according to a recent study by the Environmental Working Group in America.

The chemicals in them can cause conditions such as cancer, infertility and hormone imbalance.

Conducted on 14 to 19-year-old girls, the study found that the harmful chemicals phthalates, triclosan, parabens and musks were found in all the beauty products tested.

It also found that the longer a young girl uses the products, the more harmful they could be.

Beauty products have also been linked to depression and eye infections can occur because the products can be easily contaminated with bacteria, especially when used by young children.

Colour additives in permanent dyes used on eyebrows and eyelashes could cause blindness if they come into direct contact with the eye.

Speaking to the Kansan newspaper, Julie Toon, president of the Eye Care Council, recently advised parents to make sure their children`s eyes are safe over the festive period.ADNFCR-1853-ID-19529083-ADNFCR

GUNNAR Optiks Digital Performance Eyewear

GUNNAR Optiks claims that their products not only provide an "immediate and noticeable visual advantage" but the product greatly reduces eye strain and the affects of Computer Vision Syndrom (CVS). If you use a computer or other digital device for extended periods of time, GUNNAR Optiks has its eye on you.

Eye strain is actually one of the many symptoms of CVS as are headaches, dry eyes, blurred vision and or double vision. People that spend more than a few hours a day on a computer (*cough, cough* most of you) are susceptible to computer vision syndrome because the eye has to work extra hard to process the thousands of images and words made up of millions of tiny pixels. The human eye can focus on printed images far easier than they can on digital images or the text displayed on a computer monitor. Text and other images displayed on a computer monitor cause the eye to constantly focus and refocus contributing to eye fatigue, burning eyes, and tension. Most likely if you are reading this, you have had one or more of these symptoms if not all.

GUNNAR Optiks claims to have developed several proprietary technologies that, when used together, virtually eliminate the adverse affects of eye strain and other symptoms associated with long term computer use.

Doctors eye cure for inefficiency

All the consolidation that took place in the health care industry in 2009 could have a surprising benefit for patients: greater strides toward efficiencies in customer service.

That's because larger doctor practices that swallowed up smaller ones have deeper pockets to upgrade their information systems and other infrastructures, which the Obama administration is touting as part of health care reform and which studies have shown consumers are demanding.

These upgrades include transferring medical records from shoe boxes and file cabinets to computer systems, as well as instituting a payment system that insurers increasingly use to tie how much doctors get based on their performance or their adherence to certain quality measurements.

By instituting such measures, patients spend less time repeating their medical histories and waiting for an appointment.

"Some of these tools are very expensive, and they don't make sense for smaller practices because they don't have the financial wherewithal to implement them," said Alwyn Cassil, spokeswoman for the Center for Studying Health System Change.

According to a study this month by the Center for Studying Health System Change, a national health policy research organization, solo and smaller doctor practices are less likely to:

--Use care management tools, such as nurse managers who can coordinate patient care.

--Issue reports on physician performance.

--Conduct "group visits," which a physician uses to educate a group of patients suffering from the same illness or disease at the same time.

Often, the larger systems have the latest in technology, allowing them to offer patients better access to the latest standards and quality measures, particularly if the system is connected to an academic center or a bigger network that allows them to share best practices.

For example, Utah-based Intermountain Healthcare and Pennsylvania-based Geisinger Health System both have hundreds of physicians and highly coordinated health care practices whose electronic medical record systems are already in place, putting them way ahead of the national curve.

Analysts say it's harder for solo practitioners and those in small doctor practices to break away from seeing patients to attend an educational conference or have the luxury of bouncing ideas off colleagues in the office.

"If you're a busy physician, giving an educational pamphlet to your patient is quick and easy, but most researchers think it's less powerful than other, more demanding interventions we found were used much less often," said Dr. Emily Carrier, a senior researcher at the Center for Studying Health System Change.

About 33 percent of doctors are in a one- or two-person practice, according to the most recent statistics available from the Center for Studying Health System Change. A decade ago, the number of doctors in such practices was about 40 percent.

Some of the nation's largest health care systems say they have seen an uptick in doctors from smaller practices wanting to join them.

Advocate Medical Group, one of the largest health care systems in the Midwest, this year saw more doctors from solo or smaller practices join the company, which contributed to the 10 percent jump of employed physicians in 2009 to 700.

"The number of discussions with physicians interested in employment ... has more than doubled in the last six months," said Dr. Jim Dan, president of physician and ambulatory services at Advocate.

Analysts expect the consolidation trend to continue because hospitals and some doctors, including specialists, are expected to have their payments squeezed under health care reform.

Even those doctors who may see higher payments under health reform, such as primary care physicians, will look into joining bigger practices because of the capital needed to upgrade their offices, analysts say.

Four Kinds of Laser Eye Surgeries

In modern society, having a laser eye surgery is not only a fad, but also a more preferable way to have eyesight problems corrected rather than wearing eyeglasses. There are four kinds of laser eyesight correction surgeries which are thought to be necessary to be listed to help patients get a general view.

This first one is the flap techniques, among which the LASIK is the commonly applied one procedure. During the surgery, the surgeon cuts a small flap in the cornea, if LASIK applied, a laser beam is used to create the flap and remove the extra tissue, so that the cornea can be reshaped and regain the ability to focus objects. This procedure can also be achieved by photoablation techniques in which a kind of cool heat, mainly composed of ultraviolet radiation, is used to impair the excess tissue. Then the tissue is taken off from the cornea. The difference between flap technique and photoablation technique is that the latter comes to comparatively secondary. However, as it known to all that problems are inevitable to emerge during any surgery, so do flap techniques, during which, the flap may be put out of place causing eye soreness and blurry vision but this is of low probability, a million to one. In addition, a perforation in the eye and an irregular flap can happen at times, resulting in seeing “floaters” in vision, but those often happen when older equipment is used.

The second one is the thermal techniques, which are mainly applied to cure farsightedness. It, in both laser technique and electric probe, is achieved by heating up the pupil with thermal heat 8-16 tiny burns. Thus the cornea can be reshaped to be steeper.

The third one is the corneal incision methods. This technique is accomplished based on the principle of changing the surface of the cornea, so that vision errors are fixed. However this technique is proceded in a traditional way by using a diamond-tipped knife to make a tiny cut in cornea, it has been replaced by laser technology now.

The forth one is the implants. They are done by putting contact lenses right behind the cornea forever, which are referred as intra-ocular contact lens implant. This technique is usually applied when one’s cornea are so extremely deformed that eye problems can not be corrected by other surgeries.

After the operation, a few days or last up to a month will be taken for one to get recovered which varies from person to person. It is worth to notice that in the course of healing, people should take good care of their eyes, or some issues will occur, for that with any operation, there is certainly a risk of infection. Therefore, it is advisable not to rub eyes, and take along eye drops, which can serve as a help to keep eyes from getting dry. If your eyes are unfortunately get infected, go to see your eye doctor as soon as possible, in case of slowing the course of healing.

That’s all the kinds of laser eye correction surgeries above. If you have had enough of the trouble of wearing eyeglasses and contact lenses, it is the time for you to try the new, which will definitely surprise you a lot. Do not be worried about the accidents mentioned above, study show that laser issues happen in less than 1% of eye operations done today. Anyhow, no matter what kind of surgery you are intended to take, do consult a professional eye doctor. If permissible, consulting another one or two ophthalmologists will be great.

World Vision suggests putting something meaningful under the tree

World Vision Canada is hoping a pig, fruit trees or even school supplies will be the answer to your holiday gift-giving woes.
During the Christmas season, the Christian organization promotes its meaningful gift catalogue, which can be viewed at www.WorldVision.ca.
As part of the purchase of gifts, buyers can choose the option of sending an e-mailed greeting card, or e-card, to the gift recipient to show what their gift entails.
Last year, more than 90 Sydney residents used the catalogue to buy $14,463 worth of items ranging from livestock to school uniforms to medical supplies for children and families in developing countries.
Another 121 Sydney donors purchased $13,000 worth of items in 2007.
“People in Nova Scotia in general are very generous,” said Karen Flores, spokesperson for World Vision Canada. “We’re hoping that this year we can... just encourage them to continue to donate to the catalogue and make a difference in someone’s life.”
World Vision says its gift catalogue helps poverty-stricken communities bring about a sustainable change.
The purchase of gifts also includes training to ensure families can use the animals and plants they are given to improve their children’s health for years to come.
“The online version offers over 80 gifts to choose from,” said Flores. “So even if you’re stumped you know literally minutes before Christmas you can still purchase a gift and get an e-card sent to whoever is getting the gift. There’s still tons of time left.”
Prices for animals also include pen construction, pen material, vaccinations and feed.
World Vision is a Canada's largest private relief and development agency.

Types and terms of magnifying glasses

Some people need magnifying glasses in certain circumstances, such as reading a newspaper, a book, the fine print on a map, a menu as well as examining a diamond or gemstone. Currently, there are various kinds of magnifiers, including Head Visor magnifiers and pendant necklace magnifying glasses. The first criterion is that the type of magnifying one chooses should match the use of it.

Magnifying glasses are now provided in different styles and designs. And different people need specific magnifying power. For instance, ordinary people may use a 5x hand held magnifier to examine windshield for defects. A pocket 10x folding magnifying glass is helpful for a border protection department as well as a police department. In addition, 20x jeweler loupes can be used by a county department of agriculture to examine crops for insect and blight problems.

For general reading, hand held magnifiers are convenient and helpful. For newspapers or books, people always use a magnifier with 3x or 6x magnification and 3 or 4 inch diameter. And for finer print materials, magnifiers with 8x or 20x magnification are needed. For people with low vision, magnifying glasses in standard design are not competent and they may resort to electronic vision aids which can offer greater magnification.

The following is the explanation of several terms of magnifying glasses. Magnifying power means the ability of a magnifying glass to increase the visual size of an object. A magnifying lens simply bends light in a special way and makes an image looks larger than an actual object. The X indicates the magnifying power. For instance, a 3x glass triples an image and 4x magnifiers magnify an object 4 times.

Focal length or working distance is another way to classify magnifying glasses. This element represents the distance that should be set between the magnifier and an object in order to get the optimal magnification effect. For example, a lens with 2x magnification and 5” focal length means that the lens can provide double magnification when it is held at a distance of 5” from the object.

Field of view simply indicates the size of the area that a person sees through the glasses. Depth of field is the distance that a magnifier can be moved above an object and still maintains focus ability. In general, depth field decreases as magnification power increases.

Get Rid of Dry Eye Syndrome

Some people experience eyes sticking shut when they wake up; some people feel eyes too dry to have a clear vision; some people wearing contact lenses encounter contacts falling out, but few of them know why they have these experiences. The truth is that they suffer from dry eye syndrome which is caused by various factors, such as checking the computer screens for a long time, eyes exposing to polluted air, dry air, poor lighting or sun for long period of time and being in aging process. Usually besides the above symptoms one's eyes will experience, dry eyes can cause a gritty, sandy sensation accompanied by burning, stinging and itching. To solve those eye problems, it is necessary and important to find out the reason for dry eyes.

Firstly, in a time when computer constitute the main tools for one to work and entertain, people spend eight or more hours a day on computer at work or at home. During this process, they are often so concentrate that they forget to blink, by which way eyes can be lubricated. Secondly, for environment being polluted, the air is reeking with more dust and dirt which are harmful for eyes. When they enter into eyes,they deposit there, making eyes hard to produce tears. Thirdly, when we get old, our bodies will be in a lack of oil, a necessary component of our tears. If we suffer from oil deficiency, water in our eyes can evaporate very quickly, thereby eyes are inclined to get dry. Fourthly, various systemic diseases such as lupus, rheumatoid arthritis, or Sjogren's Syndrome can also cause dry eyes.

Then come to the question of how to get rid of dry eye syndrome. The first and easiest way is to proceed from diet. Fish, good for both eye health and eyesight, has special effect on dry eye syndrome as well, for the reason that it contains omega 3 fatty acids which is able to increase the viscosity of oils. Taking foods rich in vitamin A or directly taking vitamin A supplements are also quite helpful. Next, take along eye drop and drip several drops when you feel discomfortable about eyes. Then wear sunglasses when you are out to reduce your eyes exposure to wind and dust, while when you are indoors, keep your house or office humidity between 30 to 40 percent.

Therefore, when you once again experience either sticking eyes or blur vision, you can make a sense that you suffer from dry eye syndrome, which results in decreased tear production and dryness in the tear film, then you are able to suit the remedy to the case.

What Makes People Suffer From Eye Problems

Eye is one of the most delicate parts in body. Many people would have experienced dry, irritated and sore eyes every now and then, but little knows what makes them suffer from those eye problems, thus finding corresponding ways to relieve those symptoms is difficult. Therefore, I think it is necessary to make clear the factors caused those eye problems, and some of the factors are listed below:

1. People working long before a computer would suffer from those eye symptoms more often. It is researched that when we stare at a computer screen, we blink about just 7 times a minute, and when we are relaxing, when blink 22 times and 10 while reading, which means that tears are less to lubricate the surface of eyes, because blinking is able to keep eyes moisturized with the protective layer of tears. (Tears, consisting of water, mucus, oils, proteins and antibodies, are of vitality in overall eye health. They are not the mere production of sorrow or excitement, and foreign objects entering into eyes. They constitute an important role in fighting against infections, protecting eyes from dust or dirt particles and keeping eyes moistened. )

2. People wearing contact lenses suffer from dry eyes more often. Contacts lenses, although some are designed to be gas-permeable, would keep eyes from breathing in some degree. Thus the surface of eyes can not be supplied with enough tears to keep them moistened. Therefore, it is advisable for contacts wearers to take their contact lenses out frequently, especially those who wear contact lenses for long term use.

3. People being allergic to pollens or as such suffer from dry eyes more often, even through a year. We usually call those hypersensitive response hay fever, which is typically associated with being most common during the summer, and people who suffer form hay fever will have red, itchy, sore and constant ' streaming ' eyes. In UK alone, many thousands of people will suffer from hay fever in summer.

4. People of inadequate estrogen levels suffer from dry eyes more often, therefore women who are menopausal frequently claim that their eyes are often very dry. Similarly, Hormone Replacement Therapy (HRT) and many contraceptive pills are researched to be able to cause not only dry eyes but also dry eye pain.

Fortunately, there are a number of solutions for those eye problems, the simplest and most convenient one is the use corresponding eye drops according to diverse eye symptoms. When you sit before a computer for an extended period of time, or wear contact lenses frequently, or overreact to grasses, pollens or something alike, or are of estrogen deficiency, you can drip one or two drops eye drops to keep eyes moistened and then you will feel comfortable. With those eye drops, especially those who have allergic reactions do not have to shut themselves away inside houses and workplaces, they can also go out as others to enjoy the full blossoming of flowers and the harvesting of wheat and rye, etc..
