Contact lenses were invented by a German oculist, A.E. Fick, as early as in 
1887 and were given the name of contact then. However they were not widely used until 1930s, because the contact lenses in early times were made of glass which is easily broken thus dangerous to eyes. And it is not until 1947, with the invention of keratoscope, that they began to become popular.
Comparing with traditional glasses, modern contact lenses do have several advantages. The images one get through them tend to be more close to the reality, especially for person with high myopia. They have no frame so they won’t press your nose and without the frame you can also get a wider range of view. And for beauty-chasing girls, contact lenses are absolutely more attractive for them than the traditional glasses.
