This article entails on the account of the discovery and history of contact lenses.
Surprisingly, it was Leonardo da Vinci who imagined and conceptualized the idea of the contact lens in the year 1508. It may be surprising that the year was 1508; but, the fact that the man to first think of and sketch the thought was the father of various far sighted notions was not surprising at all.
For over a century, there were really no developments regarding this idea of Leonardo da Vinci. In spite of everything, there were no exact and precision tools as well as knowledge to create contact lenses at the time.
Astonishingly, Rene Descartes, a Frenchman realized the need for corneal contact lenses in 1632. However, for another couple of centuries, his idea was stuck in a shelf. Then came 1801, the time Thomas Young corrected his own sight using Descartesí idea. He used a ľ-inch elongated glass tube, filled it up with water then placed microscopic lenses at the end.
Contact Lens Development
At around 1823 to 1827, Sir John Herschel, an English astronomer, brought up the idea of conforming the contact lens to the specific shape of the eye by grinding.
By 1887, a German glassblower named F Muller was able to create the first contact lenses ever that was specially designed to now cause irritation when worn on the eyes. This was a kick start for a couple of opticians, the French Edouard Kalt and the Swiss Eugen Fick, to account their successful use of contact lenses in the correction of their patientsí sight.
The first ever American to make lenses in New York was William Feinbloom. He brought up the notion of using plastic as an alternative material. Held up by The Second World War, American Optometric Association affirmed the creation and use of contact lenses as a formal practice for optometry in the year 1945.
After the approval, works on the designs of the best lens proceeded at a rate of knots. By the year 1950, the corneal lenses were designed by Dr. G Butterfield. This was considered an important step for the development of the contact lens and this even allowed the lens to be made following the eyeís shape rather than sitting on it.
In 1960, ten years later, Drahoslav Lim and Otto Wichterie began experimenting with a soft plastic that is water absorbent as a way of creating lenses. After eleven years, 1971, soft lenses were officially available commercially within the US while the remainder of the globe follows at different degrees relying on their medical bodies who rule and grants permission for the material to be used.
The Biggest Move
It is this stage that gave people the largest move in the creation of lenses that are commercially available nowadays.
Basing on the worldwide recognition of the soft lenses, people are using various styles that are available today. From Toric lenses, Rigid Gas Permeable lenses, Colored and Tinted lenses to Bifocal Lenses, all of these are various lenses born out of the development from that stage.
