PROBLEM TO BE SOLVED: To prevent the waste of preservation liquids and to prevent a lens from being washed away by means of city water when it is washed by adopting a slide type lens holder which is not rotated together with a lid. SOLUTION: A lens storing part is absolutely made to be a flat square At the least in order to cancel the waste of the preservation liquids. The slide type lens holder 3 is adopted, which can be stored in a square storing part and is not rotated together with the lid 2. A water flow port with a grid is adopted, by which the lenses 1 are washed while being stored in the case in order to perfectly prevent them from being washed away when they are washed by water. The slide type lens holder 3 is made to be a specified shape in order to simultaneously wash the both left and right lenses 1 and an attachment/ detachment action except washing the lenses by water is easily executed in a living room or the like which is separated from water circumference. The slide type lens holder 3 is easily put in/out to/from the storing part together with the opening/closing of the lid 2 by using the surface tension of moisture which is stuck by washing the lenses or the like.
