摘要: The invention discloses a pair of contact lenses with water and oxygen channel. An inwards recessed tear channel the width 0.5-1.0mm is formed in inner surface periphery an optical region center each lens; small vent holes diameters 0.5-1.5mm are has advantages that combined to form micro circulation system, so permeation flexibility lens ensured cornea anoxia relieved; permeability can reach 15-20 times general hydrogel 3-5 silicone lens, be worn for continuous days.
