PROBLEM TO BE SOLVED: To provide a curved liquid meniscus lens applicable to an ophthalmic lens.SOLUTION: The liquid meniscus lens comprises an arcuate front curve lens 606, back curve lens, and a meniscus wall 601 bordering a meniscus 604 formed between a saline solution 603 and an oil 602. The meniscus wall 601 includes multiple concave segments concave from an optical axis of the front curve lens 606. A discontinuity 609 having a shape of an outside corner is disposed between the multiple concave segments, and slows or stops movement of the meniscus 604 along the meniscus wall 601.SELECTED DRAWING: Figure 6B 【課題】眼科用レンズに使用できる湾曲液体メニスカスレンズを提供する。【解決手段】この液体メニスカスレンズは、弓形の前方湾曲レンズ６０６と、後方湾曲レンズと、生理食塩水溶液６０３と油６０２との間に形成されたメニスカス６０４との境界をなすメニスカス壁６０１とを備える。このメニスカス壁６０１は前方湾曲レンズ６０６の光学軸に対して凹面をなす凹面セグメントを複数備える。複数の凹面セグメントのそれぞれの相互間には、メニスカス壁６０１に沿ってのメニスカス６０４の動きを減速または中断させる、出隅の形状を持つ不連続部６０９が設けられている。【選択図】図６Ｂ
