Abstract
A system and method for disinfecting contact lenses produces ozone from the water in which the contact lenses are submerged, thus avoiding the need to supply ozone from an external source. Ozone is created by an electrolytic cell including a diamond electrode, which is submerged in the water with the contact lenses to be disinfected. The diamond electrode may include a number of fingers, and may be fabricated from a diamond blank.
Claims21
A method of disinfecting a contact lens, the method comprising:
- providing a chamber configured to hold a water-based liquid and to hold at least one contact lens, and configured to supply power to an electrolytic cell;
- providing water within the chamber;
- providing an electrolytic cell at least partially submerged in the water;
- and
- causing the electrolytic cell to produce ozone from at least a portion the water, the ozone dissolving in the water.
A system for disinfecting a contact lens by creating ozone in water within a disinfecting chamber, the system comprising:
- a chamber configured for holding a water-based liquid and at least one contact lens;
- an electrolytic cell within the chamber and configured to be submerged in the water-based liquid, wherein the electrolytic cell comprises a first electrode and a second electrode, at least one of the first electrode and the second electrode comprising a diamond, the electrolytic cell configured to produce ozone from the water-based liquid;
- and
- a plurality of chamber power terminals within the chamber, the plurality of power terminals coupled to the electrolytic cell,
- wherein the relationship between the volume of the chamber and the ozone-producing capacity of the electrolytic cell is such that the electrolytic cell is capable of producing a concentration of ozone with the water-based liquid of at least 0.5 parts per million.
A method of fabricating a diamond, the method comprising:
- providing a diamond blank having a plurality of faces;
- removing at least a portion of the diamond blank, such that the remaining portion of the diamond blank comprises a plurality of fingers.
The method of fabricating a diamond according to claim 20, wherein removing at least a portion of the diamond blank comprises:
- cutting the diamond blank into a first segment and a second segment, the first segment having a first plurality of fingers and the second segment having a second plurality of fingers, the first plurality of fingers interdigitated with the second plurality of fingers;
- and
- separating the first segment from the second segment.
