Description
Technical field
The present invention relates to washing contact glasses field, more particularly to a kind of nanometer electricity for electrophoresis cleaning contact lenses
Pole.
Background technology
There are the people of quite a lot of myopia, in order to attractive in appearance or action is convenient, selection uses contact lenses.However, contact lenses
Proteinosis can be caused after long-term use, eyeglass is lost oxygen permeability, the damage of cornea can be caused after wearing, therefore, when
After contact lens wear certain hour, it is necessary to cleaned, for reusing.
The most-often used cleaning way of current contact lenses, is that the eyeglass of contact lenses is respectively put into washing contact glasses
In two containers of box, cleaning liquid medicine is injected separately into, then is rubbed with finger, to remove the dust on contact lens, albumen
The dirty things such as matter deposition, mucus, oil stain, maintain the oxygen transmission rate of eyeglass.However, the easy nothing because of finger unclean of above-mentioned cleaning way
Method reaches good effect, and during cleaning, quite expends the time.
Also there are some contact lens cleaning apparatus on the market at present, using ultrasonic wave, hot type magnetic stirrer, ultraviolet
The mode such as line or ozone, but：1) ultrasonic frequency of cleaning contact lenses need to be up to more than 100KHz, and eyeglass is easily broken by physics
Bad and higher to the matching requirement between circuit and frequency, production cost is also higher；2) hot type magnetic stirrer is using electricity
Magnetic principle heating stirring, addition cleaning agent separates the adhesion of the eyeglass, and heating-up temperature is high to have false touch to scald and damage eyeglass
Possibility；3) ultraviolet has powerful lethality to bacterium, and ozone is then a kind of good oxidant and disinfectant, but cannot
Removal completely is attached to the adhesion on eyeglass.
China Patent Publication No. is the patent of invention of CN102053390A, discloses a kind of contact lens cleaning apparatus, is wrapped
