Contact Lenses

For some people, image can be everything. Take Paris Hilton, for example, who is not content with being young, rich and beautiful; she also want to join the blue-eyed blonde bandwagon. Unfortunately, her natural eye color is brown. So she wear blue contact lenses.

         But then again, let's consider the people on the other side of the grid-people suffering from vision problems. Of course, they may opt for glasses but for convenience, most of them prefer wearing contact lenses. Aside from the cosmetic advantages, contact lenses do not steam up and are more suitable if the wearer engages in a lot contact sports. Driver with poor eyesight, in particular benefit more from wearing contact over glasses since the former offers a wider field of vision  than the latter.

Contact lenses are sometimes tinted to make them more visible

when immersed in cleaning solutions.

         Adolf Eugen Fick, a German physiologist, is credited for having constructed and fitted the very first successful contact lenses in 1887. Made from heavy Brown glass, the lenses can only be worn  for few hours at a time as they were very large  and difficult to wear. It was not until the 1960s  with the development of  hydro gels that the contact lenses we see today became so popular among the masses. Compared to glass lenses, the soft gel variety are kinder  to the eyes , allowing oxygen to seep through the material. As of 1999, the most  recent development came in the form of silicone hydro gels, which can be used for daily and overnight wear.
