Nowadays, it is estimated that more than 100 million people around the world wear contact lenses. These items are very popular and technology improves them daily making them even more desirable.
Why do people wear contact lenses?
There are people who wear contact lenses, instead of glasses, for esthetical reasons. They like themselves better with contact lenses than with glasses. Another reason that determines people to wear contact lenses is the cosmetic one. There is a great variety of decorative contact lenses that can change the eye’s appearance. And there are those who appreciate their practical side. They cannot play certain sports with glasses; they use devices that are incompatible with glasses etc. There is that category of people who are forced to wear contact lenses for therapeutic reasons. In their case, the contact lens is not an option. The contact lens can be a bandage in the healing process of different diseases or injuries of the cornea and it is a luxury that heals. There is also a combination between the two reasons – colour lenses with correction power which actually please a lot of persons.
The first contact lenses ever made were developed out of glass. After that, new types appeared, as the ones made of Plexiglas and the rigid gas permeable ones, but, nowadays, the soft contact lens is the most appreciated. Modern materials include silicon hydrogel or other plastic polymers like etalficon A, galyficon A, senofilcon A (used in the fabrication of Acuvue contact lenses). Rigid gas permeable contact lenses are recommended to the persons with dry eyes as these lenses contain no water that could evaporate during the wearing.
If you decide to wear contact lenses, you first have to go to an ophthalmologist, no matter what your reason may be. The doctor will be the one to decide which type of contact lenses fit your eyes best. Different factors will be considered for the prescription of a certain contact lens: the material (the silicon hydrogel is one of the newest discoveries in the field), the wearing time (daily wear, extended wear or continuous wear), the shape (spherical, toric or multifocal) and many more. Depending of the material, the contact lens can be either rigid or soft. The rigid one can be gas-tight or gas-permeable, but the soft one is always gas-permeable. There can also be a further classification made on the moisture content, on the amount of water in the contact lens. Read more…
Before you become overly concerned about “bird flu,” there are a few important facts you need to know about this disease.
“Bird flu” is not the same thing as human pandemic flu. “Bird flu”-H5N1 highly pathogenic Asian avian influenza-is a severe disease of birds. All the people known to have gotten it had close contact with infected birds, mostly in rural villages in Asia. Where there is no close contact with infected birds, there’s no human disease.
More good news: The food supply is protected. The poultry industry and the U.S. government take Asian avian influenza very seriously because it can threaten commercial poultry. It’s spread by migratory birds, so the federal government monitors wild birds in areas where there could be contact with Asian birds.
In addition, security on poultry farms is very tight. Poultry are kept away from wild birds. Strict procedures keep the virus from being tracked into the birds’ living space. Poultry farmers’ number one priority is to protect their flocks. Read more…
Food:1. any substance taken into and assimilated by a plant or animal to keep it alive and enable it to grow and repair tissue; nourishment; nutriment.
2. Anything that nourishes or stimulates; whatever helps something to keep active, grow, etc.
But does it enable to grow and repair tissue, or give proper nourishment and stimulants to our mind and body? There was a time when this question could be answered with an astounding yes. But this certainly isn’t true anymore!
As a good example, in 1880 it was evident in the general population, that there were around 2.8 cases per 100,000 people who were diabetics. Then this rose to around 29.7 cases per 100,000 people in 1949. But then, in that same year, 1949, the manor in which they started keeping statistics was changed, to where the 29.7 cases were now 16.4 cases per 100,000 people. The consequence coming out of this change was to obscure what was actually the incredible rise in diabetic cases over this same period. Of course during that time period there was no distinction between Type I, and Type II diabetes it was known simply as diabetes. Read more…
