Glasses trivia:The world’s first contact lens was born for many years?

VIEWS

The world’s first contact lens was born in 1946 and was developed by a German designer named Hermann Welk.

When Welk was a child, he had to wear glasses because of severe myopia. The glasses brought a lot of inconvenience to his study, work and life. For this reason, he often gets upset. In order to change this situation, Werk is determined to develop a lens that is convenient.

Verk is both an electrician and a mechanical designer. He is knowledgeable and ingenious. Initially, he experimented with a plexiglass material with dielectric properties that was not successful because the lens that was produced was not directly in contact with the cornea. However, Welker did not give up on this, but insisted on research and development, and finally developed a hard micro contact lens in 1946, and achieved success. Subsequently, Welker invented a soft contact lens that is more adaptable to the human body on the basis of hard contact lenses.

The development of contact lenses has been greatly improved today. It is made of a new polymer material, hydroxyethyl methacrylate, which is a soft contact lens that is directly attached to the cornea. This lens is comfortable and convenient to use, and is very popular among myopia patients.
