A brief history of contact lenses
While contact lenses may appear to be a modern addition to eye care, but actually they had a long and illustrious history, kick-started by none other than Leonardo da Vinci and Rene Descartes.
In the late ’90s, a German glassblower produces lenses that can be seen through and are quite tolerable. The Germany optometrists came up with the first contact lens that can be worn for a few hours at a time.

While contact lenses are still the most used for vision correction, there are also contact lenses for the purpose of purely cosmetic and novelty.
