When choosing the means of vision correction – contact lenses or glasses – of cource contact lenses are more convenient. For example, using contact lenses you can wear sunglasses on a sunny day (this is especially handy if you’re driving the car). The frame when wearing corrective glasses is constantly in the field of view than its limit, while the contact lenses do not interfere with the eye to see. That’s why I chose contact lenses.
The main thing in contact lenses wearing is the right care. You must strictly comply with all recommendations of ophthalmologist and rules for the use of lenses and care for container storage. Disregarding these rules may lead to serious eye damage and the development of different eye diseases. But do not hurry to abandon such a convenient invention of mankind!

Contact lenses are made of many different types of plastic, but they are divided into 2 main groups:
- soft
- rigid gas permeable (RGP)
Soft contact lenses contain 25% to 79% water, are easy to adapt to and are quite comfortable.
Rigid gas permeable contacts provide better visual acuity, durability, and deposit resistance than soft contact lenses. Here’s a look at a comparison of different contact lenses. You choose which one is right for you.
Daily-wear soft lenses
These contacts are made of soft, flexible plastics that allow oxygen to reach the eyes. They are easy to adjust to and quite comfortable. They are also available in tints and bifocals.
Daily-wear disposable soft lenses
Daily disposable contact lenses are the ultimate in convenience. There is no need to clean, disinfect, or add enzymes to the lenses–just throw them away after each use. You simply replace it with a fresh, new, and sterile pair every morning. They are ideal for traveling because there is no need to transport contact lens solutions or cases. They are also ideal for sports because there is much less concern over the possibility of losing a contact lens.

What causes dry eyes from contact lenses?
Dry Eye Syndrome Symptoms
Persistent dryness, scratching and burning in your eyes are signs of dry eye syndrome. These symptoms alone may prompt your eye doctor to diagnose dry eye syndrome.
But sometimes your eye doctor may want to measure the amount of tears in your eyes. A thin strip of filter paper placed under the lower eyelid, called a Schirmer test, is one way to measure tear production.
Another symptom of dry eyes is a “foreign body sensation”, the feeling that something is in the eye. And it may seem odd, but sometimes watery eyes can result from dry eye syndrome, because the excessive dryness works to overstimulate production of the watery component of your eye’s tears.
According to the Schepens Eye Research Institute in Boston, approximately 10 million people in the United States suffer from Dry Eyes. One risk factor for dry eyes that might be surprising is that wearing contact lenses can actually cause Dry Eyes. Why is it that contact lenses can cause Dry Eyes? Simply stated, Dry Eyes can occur if you either don’t have a sufficient quantity of tears or if the composition of the tears you do have is not correct.

New study from the USA shows that smoking soon after waking increases risk of lung cancer, because the shorter the time between waking and having a first cigarette, no matter how many you smoke a day, the higher is your levels of circulating cotinine, a derivative of nicotine that is made in the body and which has been linked to higher risk of lung cancer.
The scientists said that smoking cessation programs should take into account the time smokers waits before they have their first cigarette of the day because it could make a significant difference to their nicotine uptake.
The leader of the research is Dr Joshua E Muscat, professor of public health sciences at Penn State College of Medicine in Hershey, Pennsylvania. “Since cotinine levels appear to reflect the risk of lung cancer, our results suggest that smokers who smoke immediately after waking may be especially at risk for lung cancer.” said Dr Joshua E Muscat. “These people may require a more intensive intervention than other smokers to help them quit smoking on a sustained or permanent basis.”

People who repeatedly recover from ordinary seasonal flu or a few times vaccinated, perhaps, to some extent are protected from the swine flu A virus H1N1, researchers from the United States reported.
They found evidence that the human immune system can partially recognize A virus H1N1 virus, which is something still similar to seasonal influenza viruses.
“Swine influenza is a bit like an ordinary flu, which may suggest that humans already have a partial immunity against it. Perhaps this can make the disease less severe among the general population than previously estimated,” – said Alessandro Sette, Ph.D. Head and Member Center for Infectious Disease in California.
The study also may help explain why many older people are not so hard to carry the disease, said Ellison Dekhat Augustine from the National Institute of Allergy and Infectious Diseases. “We adults may be a partial immunity against A virus H1N1,” – she said.
Swine flu has swept through about 22 million Americans from April to October, killing an estimated 3,900 people, including 540 children.
“We’ve been tracking influenza for decades,” says Anne Schuchat, director of the CDC’s National Center for Immunization and Respiratory Diseases. “What we are seeing in 2009 is unprecedented.”

Study Group of the Wake Forest University have successfully grown a rabbit’s penis, based on collagen and cells of rabbits. With artificial penis rabbits regained not only erectile function but also the reproduction ability, a medical conference in the U.S. has been told.
The research was led by the team of Dr. Anthony Atala, who said that the novel experiments raise hope that tissue engineering can one day be used to help men with severe impotence, or needing penile reconstruction, to regain their full sexual function.
The concept is that cells from a reduced organ are sprayed onto a collagen matrix, then bathed with compounds that stimulate cell growth and left in kept in an environment that duplicates the temperature and chemical makeup of living tissue.
