Contact Lenses - Simple History

People are often surprised to learn that contact lenses were actually invented over a century ago, when in 1887, a Germanic glassblower managed to successfully create an eye covering which could actually be tolerated by the eye (without causing permanent damage, a common problem that had dogged many earlier models!) and which also improved the vision as well.

However, it should be noted that whilst the first contact lens was successfully produced as late as 1887, the inherent defects and flaws which dogged the early contact lens were subsequently worked upon and evened out, and the usage of porous materials such as silicon which actively permit oxygen to enter into the cornea and thus oxygenate it.
