There is talk of contact lenses. Instead of wearing a pair of glasses, more and more people opt to use lenses and enjoy several amenities in the daily life. At the thought, one would like to think that this would have to be an invention of our modern times to the size/performance a lens ratio.

They often not much bigger than a little finger nail, can act with severe visual impairments and limitations wonders. But the fact is that the first form of a lens is already held in the 20th century. Idea and conception of the contact lens, just as we know it today and use, go back to the 17th century. The French philosopher and natural scientist of Rene Descartes described it in a Records a vision remedy which could be worn directly on the eye. The first lenses, which followed this idea in development and manufacturing, were made of glass. However, glass has a property that seems to be not necessarily the best for contact lenses. Glass is impervious to oxygen. Similarly disruptive and inappropriate one can imagine wearing such a lens.

Only at the end of the year 1939 succeeded inventors who have contributed a significant step with their achievement to the present form of the contact lens, to produce remedies made from acrylic glass. This could, be worn along with the reduction of the diameter to 10 mm maximum, up to 12 hours a day. Considering that even today many people about aching and burning eyes, which are caused by unusual wearing of a contact lens, complaining after a long and tiring day, is aware of how much the use of acrylic glass in the manufacture of contact lenses was worth. Today there are countless types of contact lenses, customized and tailored to the Needs and desires of the customer. Hard as the inventor of the now well-known”and soft” lenses are the gentlemen Heinrich Wohlk and Otto Wichterle.
