Beschreibung
Zusammenfassung:	To provide contact lenses containing at least one silicone-containing monomer.SOLUTION: A contact lens is subjected to Soxhlet extraction using methanol as an extraction solvent, and the weight percentage of extracted hydrophilic leachables is 1.0-8.0% with respect to the weight of the contact lens.The present invention further provides a silicone hydrogel contact lens.SELECTED DRAWING: None 【課題】少なくとも１種のシリコーン含有モノマーを含むコンタクトレンズを提供する。【解決手段】コンタクトレンズを、抽出溶媒としてメタノールを用いてソックスレー抽出を行い、抽出された親水性浸出可能物のコンタクトレンズの重量に対する重量％が１．０％～８．０％である。本発明は、他にシリコーンハイドロゲルコンタクトレンズを提供する。【選択図】なし
