    • Apparatus and methods for holding and cleaning non-permeable contact lenses which includes the application of an electromagnetic field about the contact lenses which are held in a cavity containing a conductive solution and an adsorbent membrane to capture the contaminants being removed from the lenses. Proteins, lipoproteins and other contaminants adhere to the surface of non-permeable lenses. An adsorbent is positioned between the lens and an electric current source so that current flows from the current source through the adsorbent and over the surface of the contact lens so that contaminants on the lens are loosened and migrate to the adsorbent to which they adhere, thus permitting effective removal from the solution. A lens holding device formed by a novel method is used with the cleaning apparatus and includes joined body portion sections foldable upon each other along a fold line, the sections having openings therein which align with each other when the sections are folded to form, along with closing seals, holding compartments. Depending upon current levels and the time period involved, contaminant removal can exceed 90% with the use of less than 0.25 watt of energy.
    • 用于保持和清洁不可渗透的隐形眼镜的装置和方法,其包括施加围绕隐形眼镜的电磁场,所述电磁场保持在包含导电溶液和吸附膜的空腔中,以捕获从透镜中去除的污染物。 蛋白质,脂蛋白和其他污染物粘附在不透水透镜的表面。 吸附剂位于透镜和电流源之间,使得电流从电流源流过吸附剂并在隐形眼镜的表面上,使得透镜上的污染物松动并迁移到它们所粘附的吸附剂上 允许从溶液中有效去除。 通过新颖的方法形成的透镜保持装置与清洁装置一起使用,并且包括沿着折叠线彼此折叠的连接体部分部分,其中当部分折叠形成时,具有彼此对准的开口,以及 关闭密封件,保持隔间。 根据当前的水平和所涉及的时间段,使用少于0.25瓦的能量,污染物去除可能会超过90%。
