How To Buy Discount Contact Lenses
The secret to finding and buying discount contact lenses is that you should look for a professional outlet. Your contact lens outlet should be able to supply you with discount contacts because they have a superior business model.
You definitely don't want a contact lens supplier that takes shortcuts through the system. The internet is full of questionable contact lens stores. You could place an order with a bad company that sends you the wrong prescription, the wrong contact lens brand or the wrong contact lenses altogether.
When you need a new prescription, you need it immediately. You don't have time or money to waste on sham companies that are willing to take risks with your health and your eyes. You should only deal with companies that want to protect your eyesight and your health. Your eyes are in the hands of your contact lens supplier. Hygiene and packaging is of the utmost importance.
A good indication of the quality of a contacts lens dealer is the time that it has been in business. Has it been around for a number of years or is it a recent startup? Years of experience show that a company knows what it is doing. It also indicates that the dealer has a solid base of customers who keep coming back.
Such a dealer will have an established reputation in the eye care and medical optical business. It will have solid relationships with the best and most well-known contact lens manufacturers. The top manufacturers are willing to supply them with quality discount contact lenses. It is low risk and high volume business to them and they respond with low prices and quick delivery.
You should not even consider buying no-name discount contacts, look for reputable products from top companies in America and the world. These will be companies like Bausch & Lomb, CIBA Vision, Johnson & Johnson, Wesley-Jessen, and a couple of others.
Look for discount contacts lens suppliers that guarantee purchase satisfaction, prompt shipping, safe shipping, low prices, and quality after sale service. Your eyes are worth the time it takes to do the research and find an internet contact lens supplier that can provide all of these benefits.


Bird Flu: A Global Outbreak, A Global Concern
In the 1330s, the bubonic plague killed millions of people. Transmitted by rats, the disease originated from China. It later spread to Europe when merchants came back from their long voyage from China. The disease was also spread by fleas that when passed on to humans, became fatal. The bubonic plague continued for years and took the lives of millions of people.
Seven centuries later, a new disease is threatening to kill many if precautions are not made. This new disease is avian influenza, more commonly known as bird flu. Instead of rodents, birds transmit this disease to humans. Birds carry the bird flu virus in their intestines when they migrate for the winter. The virus, which does not affect the carriers, is deadly to those who come in contact with birds carrying the virus. When chickens, birds or geese come in contact with a bird carrying the virus through the bird's saliva, nasal secretions or feces, they can become infected, fall ill and die in 48 hours.
Humans infected with bird flu have symptoms similar to symptoms of human influenza: fever, sore throat or muscle pain. Because of this similarity, it is easy to mistakenly diagnose an actual bird flu as human influenza. However, humans infected with avian flu would have worse symptoms – eye infections and respiratory problems that could become life threatening.

Influenza in pandemic proportions is recorded to have happened three times during the 20th century. The Spanish Flu of 1918, the Asian Flu of 1957 and the Hong Kong Flu of 1968 claimed at least 20 million people worldwide.
It's important to mention that humans will not usually get bird flu unless they have been in close contact with infected poultry. Since the number of people that has been infected with the disease is still low and confined to a few children and adults, there is no serious cause of alarm yet. However, scientists and the health community are concerned that the disease, which usually affects poultry livestock, may evolve into something that will adversely affect humans. In some scenarios, the bird flu virus may become airborne or transmitted from one human to another.
The bird flu virus has many subtypes, but the subtype that is proving to be fatal to humans is called the H5N1. To date, about 70 people in Asia are confirmed to have died from H5N1.
When a bird flu outbreak occurs, the entire livestock has to be destroyed. This is similar to what happened during the mad cow disease outbreak when cattle had to be slaughtered and burned in order to prevent the disease from spreading to nearby cattle areas. The slaughtering and burning of cattle were done in many countries in the Asian region as well as in some parts of Eastern Europe and Russia.
Antiviral medications such as amantadine and rimantadine, which are usually given to treat influenza, do not work on the bird flu virus. Drugs are being developed and temporarily used on patients who appear to have succumbed to the avian flu disease. Although they appear to be responding to treatment and are showing improvements, further tests need to be done to ensure the effectivity of these new drugs.
Centuries ago, particularly during the bubonic plague, medical science was not yet developed to cope with an epidemic of pandemic proportions. However, with the advances in technology today, scientists will be able to study the avian flu disease further. By closely watching the migratory patterns of birds and understanding the disease, scientists may help prevent bird flu from becoming another global outbreak.
With the help of the internet, information can be disseminated quickly to thousands of people around the world and a reaction force can be immediately deployed to stop the disease from spreading any further.
It is important for people to realize that the bird flu virus is not merely one country's problem. It is a serious global problem that affects all countries and all peoples.

Bird Flu: The Threat of Animal to Human Transmission
When bird flu hit most Asian countries, it prompted the World Health Organization (WHO) to urge China to test its wild birds, particularly geese that migrate from its waters during the harsh winter. The disease spread so fast from one bird to another that about 5,000 birds were killed in one season. People who have close or direct contact to infected poultry can contract the disease after coming in contact with bird secretions or feces.
Although many are divided on the possibility of direct human to human transmission of the virus, this possibility has not been ruled out. Viruses, in general, are known to mutate. In the case of bird flu, family members infected with it may show different severity of symptoms, prompting a misdiagnosis. Also, if a person who has the common flu becomes infected with bird flu at the same time, it can lead to the mutation of the bird flu virus.
At the University of Leicester in Great Britain, it was discovered that a full-blown bird flu pandemic could cause an 80% mortality rate. A team led by Karl Nicholson is developing the bird flu vaccine with the goal of decreasing the fatality should a fourth major pandemic occur. In the last century, there have been three recorded major pandemics: the Spanish Flu in 1918, the Asian Flu in 1957 and the Hong Kong Flu in 1968. In total, the three pandemics claimed at least 20 million people.
The bird flu virus, which can be transmitted through direct contact with a bird's infected saliva, nasal secretions and feces, can survive for up to a week at 22 degrees Celsius. At freezing temperatures, the virus can survive indefinitely. It is no surprise that the bird flu virus tends to last in colder climates and is pronounced to be almost as deadly as SARS (severe acute respiratory syndrome). In addition to the transmission of the disease from the migration of wild birds traveling great distances, the disease is also spread when contaminated birds are exported and imported in the international market.
In terms of safety in food handling and preparation, a cooking temperature of about 70 degrees Celsius is enough to kill the bird flu virus. It is important, however, to avoid raw birds and other raw markets meats from being contaminated. Cook eggs properly and check that the yolks are not runny. The simple act of washing your hands thoroughly with soap and water after handling raw meats could spell the difference. Keep in mind that transmission of the bird flu virus to humans usually happens during the slaughtering process and handling of infected bird fluids. After slaughtering infected poultry, the virus typically stays in the intestinal and respiratory tracts, not in the meat itself. Cooking at right temperatures can help avoid the virus from spreading.
The symptoms of bird flu are very similar to human flu. However, the severity of a disease can sometimes give way to announcements of a pandemic, which can cause political issues. In Asia where the incidence and actual cases of human transmission of bird flu occurred, WHO and the United States immediately took precautionary measures. The British Medical Journal, on the other hand, declared that a pandemic is still far from happening.
No travel advisory has been issued restricting anyone from going to countries affected by bird flu although WHO has issued a warning to travelers. Travelers are advised against going to live poultry markets, getting close contact to any farms and having direct exposure to feathers, feces or droppings, eggs and poultry meat products. Travelers coming from afflicted countries are also not being screened. However, precautionary measures are in place, particularly in the media. Information is being disseminated in order to make people aware of the bird flu, its effects and what to do to avoid getting infected.
Viruses are constantly mutating and evolving. Health watchers, practitioners and scientists are concerned about this because if a pandemic occurs, there won't be enough time to prepare and develop a vaccine. They fear that we are once again on the brink of another major pandemic threat. However, with the strides being made by technology every day, hopefully the casualty won't be nearly as high as the casualty of the past three major pandemics that claimed at least 20 million lives worldwide.
