Title: CONTACT LENS PACKAGING CONTAINER
Abstract:
The present invention provides a contact lens packaging container that has a novel structure, can reduce the amount of storage solution injected into a contact lens housing region, and is such that it is possible to easily remove a contact lens with one hand during opening while stably positioning and holding the contact lens in the housed state. A lens supporting surface (28), which has a convex, spherical-crown shape and is at a base-side plate (20), and a lens covering surface (36), which has a concave spherical-crown shape at a lid-side plate (22), are superposed, and at the housing region (12) formed between the facing surfaces thereof, a contact lens (18) and storage solution (16) are housed. Also, the radius of curvature of the lens supporting surface (28) is caused to be larger than the radius of curvature of the lens rear surface (38) of the contact lens (18), thus providing a gap (46) between the overlapping surfaces of the lens support surface (28) and the contact lens (18).
