When it comes to vision, the history is full of visionaries. Many people think contact lenses are an invention of the 20th Century. In fact, people have tried to find a way to ditch the glasses for centuries. Leonardo da Vinci had the idea in 1500. Since it with so many of his ideas, he made sketches of corrective lenses that would fit directly over the eye of a person.
More than 130 years later, in the 1600s, Rene Descartes wrote a book with the title in Dioptricwhich he outlined his idea for a corneal contact lenses. Later in the century, Philippe de La Hire some drawings of concave lenses on the eye.
However, it was made until 1801, that someone actually these ideas into practice. Working from the writings of Descartes, 28-year-old British doctor and all-round genius of Thomas Young created the first of the cornea, lens and tried it in his own eye.
In the late 1800s, a German glassblower creates the first glass contact lens. He watched them with German soldiers during World War II, as Nazi soldiers not allowed to wear glasses. After the war, the demand for contact lenses throughout the world. Plastic is the new material of choice rather than glass.
From the postwar period, contact the development really took off. Hard lenses have been sold commercially in the early 1940s. In the early 1970s, the first soft contact lenses> Lenses were put on the market by Bausch & Lomb.
For the next 30 years, there was an explosion in the popularity of contact lenses. Today we can buy disposable contact lenses, colored contact lenses, and lenses with UV filters in them. It remains to be seen what developments in contact lenses and vision correction in the 21 Century experience. Are we going to throw away all our objectives for the benefit of laser eye surgery a day? If somethingdeveloped quite differently in order to improve vision? Perhaps there is a modern Leonardo da Vinci sketched his ideas for a new way of seeing.
