Question 1: Who invented contact lens

Leonardo di ser Piero da Vinci

Question 2: What is silicone hydrogel?

Different from ordinary hydrogels, elements such as "silicon" and "fluorine" are added to the material. The oxophilicity of the elements itself forms a unique channel for oxygen, which does not depend on the moisture content of the lens.

Question 3: What is the oxygen permeability?

The oxygen permeability (DK/t) refers to the amount of oxygen permeation per unit thickness of the lens. The higher the value of the oxygen permeability coefficient (DK) and the oxygen permeability (DK/t), the higher capability to deliver oxygen to the eyes. 

Question 4: What is the relationship between silicone hydrogel and high oxygen permeability?

The "silicon" and "fluorine" contained in the silicone hydrogel material itself can form a unique oxygen channel, so as to greatly improve the oxygen permeability, which is the guaranty of high oxygen permeability.

Question 5: What is plasma anti-precipitation technology?

Plasma technology is involved in forming a protective film on the surface of the contact lens and the thickness is only 1/100,000 of the hair. Because it is full of charged ions and electrons, under the action of biological principles, the deposited protein ionizing dissociation occurs, essentially addressing the consequences of protein precipitation. At the same time, the protective film is hydrophilic which makes the surface more moisturized and more comfortable to wear! In addition, this technology solves a fundamental problem, which is prolonged wear. Because of protein precipitation, many lenses must be trashed after wearing for a period of time. Once the precipitation problem is solved, long time wearing of contact lenses becomes possible.
