1. A method of providing for cleaning of contact lenses, comprising: Providing a liquid-tight contact lens case configured for daily contact wearing use including lens storage and for carriage about the person of a contact lens wearer;providing a contact lens;providing a contact lens solution;providing a sonicator;placing the contact lens and said contact lens solution in said contact lens case;closing said contact lens case, further comprising the step of providing a liquid-tight seal isolating said lens and said solution within said case;placing the closed contact lens case in the sonicator;activating the sonicator for sufficient time to clean the lens within said liquid-tight contact lens case;removing said contact lens case from the sonicator;whereby the lens can be cleaned in a contact lens case configured for daily wear use, enabling a single such case to be used for both daily wear and cleaning of the lens, and also enabling improved cleaning of the lens and liquid-tight contact lens case and preservation of attributes of the lens using said liquid-tight contact lens case and a contact lens solution within said case in an amount accommodated within said case. 2. A method as set forth in claim 1, further comprising the steps of: using the liquid-tight contact lens case for both cleaning and for daily wearing use, whereby a case used for lens storage and carriage about the person of a lens wearer is cleaned at the same time a wearer's lens is cleaned;removing the lens from said liquid-tight contact case and preparing it for insertion in the eye as for daily wear;emptying said case;refilling said case with contact lens solution. 3. A method as set forth in claim 1, wherein the step of providing a sonicator further comprises the step of providing a sonicator that employs at least one of a) an ultrasonic cleaning frequency and b) a power level of at least 20 watts. 4. A method as set forth in claim 1, wherein the step of providing said contact lens solution further comprises the step of providing at least one of a sterile saline solution and a contact lens cleaning solution and a contact lens disinfecting solution. 5. A method as set forth in claim 1, wherein the step of providing a sonicator further comprises the step of providing a sonicator further comprising a timer, and further comprising the step of controlling sonication time using said timer. 6. A method of cleaning a contact lens, comprising: a) placing a contact lens in a contact lens storage case with contact solution; b) sealing the contact lens storage case with the contact lens therein; c) placing the contact lens case in a sonicator with water; d) sonicating the water, contact lens case, contact solution, and contact lens; and e) removing said contact lens case from the sonicator; wherein said contact lens case is a liquid impermeable contact lens case configured so as to protect the lens for daily wear use and carrying about the person of a contact lens user. 7. A method as set forth in claim 6, where said sonicator enables a cleaning power level of at least 20 watts. 8. A method in accordance with the method set forth in claim 6, further comprising the step of providing a sonicator configured to clean at an ultrasonic frequency. 9. A method in accordance with the method set forth in claim 6, further comprising the step of providing a contact lens case which, in combination with said lens and said solution enclosed therein, is buoyant in water. 10. A method in accordance with the method set forth in claim 6, further comprising the step of providing for sonication which further comprises a step selected from the following steps: a) coordinating cleaning time with sonicator power level so that longer cleaning time is associated with less power and shorter cleaning time is associated with higher power;b) using a lower cleaning power setting for sufficient time to clean the lens; andc) using a power level sufficiently high to clean the lens in under 6 minutes. 11. A method in accordance with the method set forth in claim 1, wherein the step of providing a liquid-tight contact lens storage case includes the further steps of providing two lens chambers in the case, each chamber being coverable by a removable cover which can be tightened down to provide an essentially liquid-impermeable seal. 12. A method in accordance with the method set forth in claim 1, further comprising the step of providing a sonicator that employs a liquid cleaning tank. 13. A method in accordance with the method set forth in claim 12, wherein the step of providing a sonicator that employs a liquid cleaning tank further comprises using a liquid in the cleaning tank consisting essentially of water. 14. A method in accordance with the method set forth in claim 1, further comprising the step of providing for sonication which further comprises a step selected from the following steps: a) coordinating cleaning time with sonicator power level so that longer cleaning time is associated with less power and shorter cleaning time is associated with higher power;b) using a lower cleaning power setting for sufficient time to clean the lens; andc) using a power level sufficiently high to clean the lens in under 6 minutes. 15. A method in accordance with the method set forth in claim 1, further comprising the step of providing a liquid tight contact lens case that is buoyant in the liquid in the cleaning tank when closed with a lens and contact lens solution carried therein. 16. A method in accordance with the method set forth in claim 1, further comprising the step of providing said sonicator configured to enable cleaning a plurality of lenses at one time. 17. A method of providing a contact lens cleaning system, comprising combining at least the following:a contact lens case, which can be of a configuration enabling daily use, having a compartment which can be sealed liquid-tight and is configured to receive and contain and protect a contact lens and a contact lens solution;a contact lens solution, which can comprise at least one of a) sterile saline solution b) lens cleaning solution and c) lens disinfectant solution;a sonicator, which can be an ultrasonic cleaner, said sonicator configured to receive a liquid in a liquid container portioninto a kit; andmaking said kit available for use as follows a) place a contact lens in a contact lens storage case with contact solution;b) seal the contact lens storage case with the contact lens therein;c) place the contact lens case in a sonicator with said liquid;d) sonicate the liquid, contact lens case, contact solution, and contact lens; ande) remove said contact lens case from the sonicator;wherein said contact lens case protects the lens for daily wear use and carrying about the person of a contact lens user. 18. A method of providing a contact lens cleaning system as set forth in claim 17, further comprising the steps of combining with other kit items a contact lens; and,making same available for use. 19. A method of providing a contact lens cleaning system as set forth in claim 17, further comprising at least one further step from the following steps: in said combining step, the further step of providing a sonicator that can operate at a power level of at least 20 watts; and,in said combining step, the further step of providing a sonicator that can operate at an ultrasonic frequency.
