The History of Colored Contacts
With dramatic advancements in technology in the last few decades, it is now possible to use contact lenses to cosmetically alter the appearance of eyes. To trace the history of colored contacts, one first needs to know the history of contact lenses in general. Although Leonardo Da Vinci is often credited with having conceived of the first ever contact lens in his book Codex of the eye, Manual D, it was not until 1887 that F.E. Muller, a German glassblower, developed an eye covering that could be worn bearably. German physiologist Adolf Eugen Fick had grabbed hold on the concept within a year's time and created the first wearable contact lens. Sadly it was very unwieldy, large and could only be worn a few hours at a time.

In 1949, the first "corneal" contact lenses were developed, which could be worn 16 hours at a time. PMMA corneal lenses were causing quite a stir by the 1960's as people with poor eyesight were finally able to experience what it was like not to wear glasses. What came clear with more time, however, was that PMMA corneal lenses came consequences: the lenses did not allow any oxygen through the lens to the conjunctiva and cornea. "RGP" lenses (rigid gas permeable) were developed to remedy this problem, but were of course quite uncomfortable for the wearer. Czech chemist Otto Wichterle finally developed the first soft contact lens, which was approved by the FDA in 1971 and forever changed contact lenses for public usage.
Today, a wide variety of colored contact lenses are available for purchase for prescription or cosmetic use (the latter are called Plano, or zero-power contacts.) Most commonly people with brown eyes want to try a lighter color, as lighter eyes are frequently portrayed as being more desirable. However, lighter eyes tend to absorb sunlight more easily and cause sensitivity, so there is in fact a price to pay for their loveliness. Brown eyes can often deepen a rich and sensuous appearance as well, which blue eyes cannot necessarily duplicate. Each color has its own depth and beauty, and the existence of colored lenses make it possible for us to play with all of them.
