     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 11a thereof, a new and improved contact lens cleaning apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the contact lens cleaning apparatus 10 of the instant invention essentially comprises a container 11, including a door 12 removably mounted relative to an end wall of the container 11, with the door 12 including a latch 12a of a desired construction to permit securement and latching of the door relative to the housing. A front wall 13 of the container 11 includes a transparent viewing window 14 positioned in alignment with a lens support housing 20 mounted within the housing upon a support, wherein the support aligns a drive gear shaft 24 therethrough that includes a driven gear 23 at a lower terminal end thereof. The driven gear 23 cooperates with an output drive gear 22 of an associated drive motor 21. If desired, the door latch 12a may provide an electrical inner lock with the drive motor 21 to prevent its actuation in the event that the door 12 is not properly mounted relative to the housing 11, in a manner known in the prior art. Control for operation of the drive motor 21 is mounted upon the front wall 13 to include a speed selector switching 15, as well as a timer panel 16 operative to effect timing of the motor 21, to include an LCD readout 17 to indicate available time remaining in operation of the drive motor. Further, conventional start and cancel switching 18 and 19 is further provided for control of the device utilizing controlled mechanism circuitry readily available to one of ordinary skill in the art. 
     The lens support housing includes a housing bottom wall 26, with the housing bottom wall 26 including a bottom wall opening 32 defined by a predetermined diameter directed therethrough. The agitator impeller 25 is mounted rotatably within the housing bottom wall 26 directed through the bottom wall opening that is coaxially aligned with the support housing 20. The agitator impeller 25 includes plural pairs of blade members to include a first pair of first blades 28 and a second pair of second blade 28a, wherein each pair are orthogonally aligned relative to one another and radially mounted relative to the shaft 24. Each of the blades 28 and 28a includes respective first and second blade slots 27 and 27a that receive the bottom wall of the support housing 22 therewithin. In this manner, an impeller positioning hub 33 radially positioned medially of the slots defined by a predetermined external diameter equal to the predetermined internal diameter of the opening 32 rotatably mounts the impeller. Appropriate sealing may further be provided about the opening 32 within the bottom wall of the housing to enhance sealing of the impeller relative to the housing. 
     Further, the housing 20 includes a housing lid 29 that orthogonally mounts a plurality of support legs 30 downwardly therefrom, wherein the support legs 30 are arranged parallel relative to an axis defined by the housing 20 and each include an opened mesh lens container 31 mounted at a lower terminal end of each support leg for receiving a contact lens therewithin. 
     FIG. 7 illustrates a modified blade structure 128 that includes a primary conduit 34 mounted to a side wall thereof. The primary conduit 34 includes a first branch conduit 36 directed to a side of each blade, and a second branch conduit 37 directed to an upper top edge of each blade to include and terminate in a side outlet 36a and a top outlet 37a. An entrance funnel 38 is mounted adjacent a lower edge of each blade 128 to receive fluid therewithin and thereby transmit the fluid through the conduits 34, 36, and 37 for enhanced agitation of fluid within the support housing 20. Further, blade slots 39 (see FIG. 8) may be provided throughout the blade 128 to provide a misting and enhanced agitation of the fluid as the blade 128 rotates about its shaft 24. 
     Finally, the blade structure 128 optionally incorporates splash cups 40 that are mounted to resilient support mounts 41 extending radially outwardly of each blade mounted to a side edge of each blade, wherein the splash cups each include a concave cavity to enhance agitation and the splashing of water within the housing during rotation of the impeller structure, as illustrated. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
