How Were Contact Lenses Discovered?

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.

The Breakthrough

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.

How Was The Keyboard Invented

The keyboard is a very useful tool nowadays. Every computer, every cellphone and every iPad has a keyboard. It is crucial in the PC which most of use today for various important reasons. This article will orient to you about how the keyboard was discovered. Certain events on C.L. Sholesí study on how to make typewriters better are taken into account. The QWERTY arrangement of the letters to be punched/pressed is also found on this topic. Take a few minutes or seconds of your time to learn more about how the keyboard was discovered

An Introduction To The Typewriter Model

The QWERTY keyboard has been with us for over a hundred years already. It is now referred to as the universal keyboard, for reasons that we use it all the time as a model for various keyboard. The QWERTY keyboard was first made to use by an inventor named C.L. Sholes. He put together different prototypes for different kinds of typewriters that were to be used in certain machine shops in Milwaukee. It was during the 1860s that the universal keyboard was discovered.

C.L. Sholes

C.L. Sholes has been accused of deliberately putting the arrangements of his keyboards for bad reasons. People thought that the QWERTY was a burden. Fast writers thought that the arrangements of the keys were able to slow down their typing powers. C.L. Sholesí purpose for creating the QWERTY keyboard was actually the opposite of what these people thought.

The First Typewriter Model

When Sholes first made a different keyboard model ( not the QWERTY) in the 18th century, the keys were in alphabetical order, and they were lined up in two rows. The first typewriters were very slow and sluggish. They also easily jammed, and precision was never something the typewriter had. Sholes devised a way to solve these keyboard problems. He tried to rearrange the letters. They first typewriter had their letter placed on the end of rods known as typebars. These so called typedbars hung in a circle. The mechanisms of how the typebar did its job in punching letters were very primitive. You could say that it was a bit similar to the typewriters in the 50s, but even then, it was still too old.

The QWERTY Arrangement

Sholes decided to use the QWERTY arrangement of the after studying letter pair frequencies under the guidance of educator Amos Densmore. Amos Densmore was the brother of Sholesí financial backer James Densmore. The arrangement was very important and very useful since it prevented the letters on the typewriter from jamming. No two words that were often used regularly were to be placed close to each other. For example, the words T and H were placed close, but not too close since they are usually used in several word (the, bath, math, etc.). Sholesí solution of using the QWERTY arrangement of letter was not able to solve the typewriter jamming completely, but it did greatly reduce the problems from occurring.
