ABSTRACT:
An appliance for disinfecting contact lenses utilizes a disinfecting solution, such as hydrogen peroxide, that liberates a gas during disinfecting action. The appliance has a container body with a removable cap that provides a sealed chamber except for a vent opening through the cap. A hydrophobic membrane filter is disposed across said vent opening and is substantially impermeable to the disinfecting solution but permeable to the liberated gas.
