What is a silicone hydrogel lens? What is different with the ordinary contact lenses?

Silicone hydrogel (fluorinated siloxane) is now a new contact lens materials. It has broken the limitation of common hydrogel contact high oxygen permeability and low water retention cannot coexist glasses, by consumer recognition of the most comprehensive, and silicone hydrogel is even called the best current contact lens production materials.
Silicone hydrogel and regular contact is different: it has the dual phase structure (fluoro silicone hydrogel materials and two kinds of channel). The main function of fluorine silicon channel is efficient oxygen permeability, and hydrogel channel is relatively soft, but also transparent oxygen. Silicone hydrogel material is low moisture content of materials, the lens can not dehydrate deformation, moisture is not easy to dry eyes. After medical identification, silicone hydrogel lenses can obviously improve eye anoxic condition, effectively ensure the long-term health of cornea, bring oxygen permeation performance sufficient for users, white and healthy eyes wearing new experience.
