Abstract
Cleaning contact lenses by placing each contact lens in a daily use contact lens case with contact lens solution such as sterile saline or lens cleaning/disinfecting solution, placing the case in a liquid in a cleaning tank of an ultrasonic cleaning device operating at a frequency and power level sufficient to clean each lens in a convenient time period.
Claims19
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.
