Invention of the Contact Lens

Invention of contact lenses dates back before the year 1877, when Adolf Fick, Eugène Kalt and August Muller in the first contact lens made of glass. Leonardo da Vinci create graphics packaging concept of eye lid early as 1508.

In 1801, young Thomas decided to work on a device to help correct your vision. What do young people appropriate glass tube filled with water with a microscopic lens. However, it will be many years before anyone develop a device that could fit on the eye itself.

Until we get to that date, in 1887. VIC and Kalt and Mueller made the first known contact of thick glass covering the whole eye. As one might imagine, wasn’t very comfortable wearing such an object. However, they were able to correct some vision problems, but because of the comfort issues, patients who could not keep the lenses in their eyes for more than a few hours.

In the early part of the last century, scientists came to the rescue. In 1934, created a new plastic called bolimithelmithakrilati (PMMA), which was to revolutionize the development of contact lenses. The patent was issued in 1948 to Kevin t PMMA contact lenses first, first fixed lens. These lenses were much easier to fit and wear of former counterparts rather than fit the whole eye, were small enough to fit only the cornea PMMA lenses. During the early 1960 ‘s, using contact lenses, contact lens fittings, the majority of implemented using PMMA hard lenses.

Then, in 1971, introduced by Bausch & Lomb soft contact lenses first to the United States. Soft lenses were made of very thin and pliable, which was largely water based. Comfort levels in contact lens wearers increased dramatically, and long lenses has become the norm. However, while still more comfortable than their counterparts of PMMA, soft contact lenses were not perfect. It’s a living organ, eyes require oxygen in order to remain intact. Despite increased comfort, soft contact lenses were unable to allow enough oxygen to the eye.

So, science came to the rescue again, with the aid of Silicon feedstock, rigid gas permeable created contact lenses (RGP). As the name suggests, gas permeable lenses oxygen by allowing the eye and help them stay healthy, even during extended wear. Some comfort issues that emerged anew, because hard rgp lenses and it takes a little getting used to. However, the effort often deserves because they’re the best for the health of your eyes.
