摘要: There are provided extended-wear lenses formed by polymerizing an organosilicon monomer system, at least a portion of which is hydroxyorganosilicon monomer, fluoroorgano hydrophilic and crosslinking agent. A UV-absorbing agent optionally present. The product easily machinable to any prescription, permitting continuous wear, with oxygen permeability in excess 50×10 -11 (cm 2 /sec) (ml O ×mm Hg).
