Contact lens having no interference fringe in the center, method of analyzing the change of the interference fringe, and system for monitoring changes in intraocular pressure
A contact lens having no interference fringe at the center, a method for analyzing the change of the interference fringe, and a system for monitoring changes in intraocular pressure. A contact lens having no interference fringe in the center of the present invention, a method for analyzing the change of the interference fringe, and a system for monitoring a change in intraocular pressure relate to a contact lens having a first material layer and a first pattern. When the first material layer has a central area and an annular area around the central area, and the contact lens is disposed on the eyeball surface, the central area corresponds to the pupil of the eyeball, and the annular area is the eyeball The first pattern is formed in the annular area and is formed by a plurality of first sub-patterns spaced apart from each other, the first pattern overlaps the second pattern, and interference fringes are formed. Configured to form. [Selection] Figure 2【課題】中央に干渉縞がないコンタクトレンズ、その干渉縞の変化を分析する方法、及び眼圧変化をモニタリングするシステムの提供。【解決手段】本発明の中央に干渉縞がないコンタクトレンズ、その干渉縞の変化を分析する方法及び眼圧変化をモニタリングするシステムは、第１材料層と、第１パターンを有するコンタクトレンズに関し、前記第１材料層が中央区域と、前記中央区域周囲の環状区域を有し、前記コンタクトレンズが眼球表面上に配置されたとき、前記中央区域が眼球の瞳孔に対応し、前記環状区域が眼球の虹彩に対応し、前記第１パターンが前記環状区域内に形成され、間隔をあけて配置された複数の第１サブパターンにより構成され、前記第１パターンが第２パターンと重なり、干渉縞を形成するように構成される。【選択図】図２
