Abstract
A lens storage container includes an integrally formed receptacle member having a spheroidal well providing a concave recess in which the lens is disposed. In some embodiments, a lip extends about a portion of the periphery of the well to maintain the lens in the well therebelow. In other embodiments, a depending portion on the closure extends into the well to keep the lens in position. A closure extends across the well and is secured to the receptacle.

A package containing a contact lens and saline solution comprising:
- (a) a container providing a well with a concave surface having a first radius of curvature;
- (b) a concave contact lens disposed in said well adjacent said concave surface and having a second radius of curvature approximating that of said container concave surface;
- (c) saline solution in said well about said lens;
- and
- (d) a removable cover extending over said container to seal said contact lens and saline solution in said well, said container well having retaining means extending inwardly of said concave surface of said well below the upper end of said well and above said contact lens, said retaining means extending about at least 200.degree. of the circumference of said well and inwardly of the periphery of said lens to limit movement of said lens towards said upper end of said well.

- (c) saline solution in said well about said lens;
- and
- (d) a removable cover extending over said container to seal said contact lens and saline solution in said well, said container well having an inwardly extending projection providing a lip on said concave surface of said well below the upper end of said well and above said contact lens to limit movement of said lens towards said upper end of said well, said projection extending over and inwardly of the periphery of said lens, said projection extending about 200.degree.-300.degree. of the circumference of said well to provide spacing between the ends of said projection to enable said contact lens to be moved by the fingertip of a user through the spacing between the spaced ends of said projection.
