Abstract

A találmány folyadékkal töltött, változtatható fókusztávolságú lencse,amelynek az egyik lencsefelületet alkotó tágítható membránja (15)valamint a membrán (15) szabad tartománya kerületmenti részének amegtartásához előirányzott membrántartó tagja (16) van. Amennyibentorikus alakkal kiképzett résszel rendelkező membrántartó tagot (16)alkalmaznak, a membrán (15) megtartása úgy történik, hogy van egy köralakú szabad tartománya, tekintet nélkül a lencse kerületének azalakjára. A membrántartó tag (16) torikus része keresztmetszetbenelőnyösen közelítőleg körív alakú, és a membrán (15) olyan helyzetbenvan megtartva, hogy kerületmenti tartománya érintőlegesen csatlakozika torikus részhez.
