The idea of placing corrective lenses right or directly at the surface of the cornea of the eye is not really a post modern eye care innovation thing; hence its original blue print can be dated way back in high Renaissance period where the famous Florentine artist Leonardo Da Vinci sketched the idea of first contact lens that will aid vision and change human eye’s corneal power.
Past versions or models of contacts are in fact unwieldy and uncomfortable to use for it is made up of fine glass. But today’s contact models offer both comfort and style as it never fails to aid vision and help people (especially young people )deal with various eye and vision problems.
It was in 1630s when a French Philosopher under the name René Descartes proposed the idea of using the lens, placing it directly right at the surface of the cornea. He proposed in the invention of liquid-filled glass tube to aid poor eye vision.
At 1801, a scientist named Thomas Young developed René Descartes’ proposal by operating experiments with the use of liquid-filled eye cups, which outer end contained a microscopic lens.
John Herschel in 19th century then proposed the same idea with the use of jelly-filled capsule and corneal mould. Though it was said that Herschel never tested his idea at first place, his proposal was then used in various studies and experiments for the development of today’s modern version of contacts. His proposal has even led to the invention of the lens that can shape and fit the eye.
After 40 years, a German under the name of F.E. Muller made the first usable contacts that are made up of glass. These are of course, not very comfortable to wear, and in fact painful to the eyes when worn for hours.
Since then, its history has got a long way, and various experiments and studies have been conducted to develop Da Vinci’s contact lens concept. Various changes are made for different purpose or use of contact lens. Nowadays, we can find not only corrective contacts for the eyes but also colored contacts for fashion purposes.

In the past, I always bear very complicated feeling towards eyeglasses. But now, I have to say eyeglasses have changed my life, or should to say have enhanced my standard of living. Let me tell you what have happened to me.
As a mailman, I had to deal with a lot of letters and other documents every day. And during the past twenty years, I found my eye sight suffered a lot. Particularly, about five years ago, I found my vision declined greatly. Objects around me became blurry and even I could not clearly see my colleagues’ faces.
Since then, I performed very badly in my work and I was reproached by my boss and I felt very disappointed. I did not know what to do or how to do? I had told this to my close friends and my wife. Their ideas fell into two opposite groups- some of them suggested me to do some natural eye exercises, whereas others suggested me to wear eyeglasses. The first group said those eye exercises were really nice and eyeglasses may lead to even worse vision degeneration. While the latter group affirmed that eyeglasses were useful and safe for me. Each group had raised a lot of examples and theories, and then I became confused. I did not know which of them was correct.
I had tried to do the exercises for some weeks, but I found it can not work, for each day I had to lower my head while working. I thought it was not a good idea to wear eyeglasses in such a rushing way. I needed more time to consider.
One weekend, I was scanning on some websites. Suddenly, some titles stroked my eyes. I could not control my excitement and read the information in one breath. I found this page very useful for me, or exclusively for me. I told myself I should reconsider my attitude towards eyeglasses. Maybe it was a good idea to search for more information about those glasses. I had spent all the weekend gaining such information.
After that, I decided to consult with some eye doctors, for I just wanted to assure that what I knew was correct. With the suggestions of those eye doctors, I confirmed that I was in need of eyeglasses.
More surprises were ahead of me, after I had entered the optical stores. I had bypassed optical stores many times, but never had I thought they are so fabulous. The optometrists had prescribed for me. I found those prescribed lenses very magical, for I could see anything before me. The staffs also suggested me to select some frames that I loved most. I could not decide which ones to choose from, for the items were dazzling. A last, I selected one frame that made me more like a gentleman.
With the new eyeglasses, I found my world became much brighter and people around me much kind-hearted. What surprised me most was my working performance had gained great praise.
Now, with my beloved eyeglasses, I think I have regained and gained a lot. My wife says I am much more attractive, my friends think I am more confident. And my boss always praise that I have done very good job. I just wonder why not wear eyeglasses earlier. Till now, I have not found any degeneration in my eye sight, but enhancement and happiness.
