Early glasses is nothing but a single piece of glass without a frame. The latter originating from the "Reading stone" was a long one. It was both aided and retarded by social condition style, quality of available materials and technology. It is reasonable to make a few conclusions about the invention along the line suggested by Rosen; most likely, the inventor was a lay person of Pisa who wished to keep the manufacturing processes a secret in order to make a profit, the date of the invention is most likely around 1270 - 1280. The inventor was by two missionaries of St. Catherine's Friar dirdano da Rivolta and Alessando Spina. Lastly, the author advocates the use of CR-39, based on the following reasons: a high resin plastic, fragile resistance, high refractive index, light weight, and resistance to fogging.

The Zhulin (Bamboo Forest) Temple was established in the southern Qi Dynasty. Buddhist monks in the Temple began their study on TCM in the 8th year of Tianfu reign of the Later Jin dynasty. However, it was not until the 6th year of Shaoding reign in Southern Song dynasty that it was named "King of Medicine" and became world famous.
