60 years ago, the earliest contact lenses were RGP hard lenses; later, soft contact lenses used HEMA hydrogel materials to replace hard lenses; now technological advances, contact lenses made of high oxygen permeable soft hydrophilic material silicone hydrogel have become the hottest new technology product in the world.

Silicon hydrogel is a polymer polymer material containing silicone and hydrophilic. It has a "honeycomb" structure and can transport oxygen through two channels: silicone phase and hydrogel phase, thus having higher oxygen permeability and is used to make high-end contact lenses.
The third generation silicon hydrogel contact lenses perfectly solve the problem of high oxygen permeability and hydrophilicity inability to coexist.
silicon hydrogel material allows oxygen to reach the eyes through two channels. Its unique high oxygen permeability formula and excellent water content ratio have huge advantages for users with long-term wear of contact lenses and sensitive eyes.
