Igenics Review

oleh Nishish Sandy (2019-05-04)

A combination of plastic and glass were melded together to form the first commercial contacts in 1936. Igenics They were lighter and better tolerated then the heavy glass lenses of the beginning days. It was in 1949 that the first lens to actually curve to the cornea came out and could be worn for up to 16 hours a day.
The lenses that came after those earlier ones, in the 50's and 60's were very expensive and those who could afford them were urged to take out contact lens insurance. The need for insurance became a thing of the past, like the old thick glass contacts, back in 1994 because contacts became less fragile and many were now disposable. They remained on the expensive side, but insurance was not something that was necessary.
The flexible material was still less 'breathable' and caused a whole host of eye problems for those who were susceptible to eye irritations or infections. The 'soft-lens' materials were introduced in the early 70's and approved by the FDA, Food and Drug Administration, at which time millions of people began taking off their glasses and switching to contacts. These lenses were better in terms of the oxygen they allowed to penetrate through the lens and onto the cornea, an important aspect of good eye care.
Disposable lenses came from a British optometrist, Rishi Agarwal. The idea that someone could wear a contact and then throw it away after a day's use was unheard of until 1972. This revolutionized the industry and a whole new group of glass wearers began to convert to contacts. There were and always will be those people who can not or will not tolerate something lying on their cornea, no matter how comfortable, lightweight or 'breathable' it is. This is why the eyeglass manufacturing industry is still going strong even though contacts are as popular as ever.
It is estimated that there are over 125 million individuals who wear contact lenses in the world today, approximately 38 million of them are in America and 13 million are located in Japan. The lenses prescribed in Japan and other countries are mainly the more ridged style and the ones in the United States are typically the soft style. Both styles come with a thin layer of UV protective coating because manufacturers and eye doctors know how important it is to protect ones eyes from the dangers of the sun.
Of course, like most people, I've considered the option of going for laser eye surgery, more commonly known as LASIK. Still, going for such a vision correction procedure is usually out of reach for a lot of people due to its high cost. At the same time, no matter how advanced the technology, there is always a slim chance of undesirable side effects, and in the worst case scenario, even blindness!
