  • Publication number: 20080276971
    Abstract: A device for cleaning contact lenses comprising a solution chamber and a motor (4) adapted to impart a reciprocating and vibrational motion to a contact lens holder (3). The contact lens holder (3) is adapted to receive one or more contact lenses, which holder, in use, is for insertion in the solution chamber (2), the holder (3) being adapted to permit fluid flow to the contact lens or lenses. The holder has first and second baskets (34,36) each adapted to receive a contact lens, which lens has an inner and an outer surface, the first and second baskets being oriented such that, in use, the respective inner surfaces of the contact lenses are remote from one another. In use, the reciprocating and vibrational motion imparted to the contact lens holder (3) generates bubbles in a solution in the solution chamber (2), which bubbles contribute to fluid turbulence at a surface of the contact lens, thereby assisting in the cleaning of the lens.

  • Patent number: 5129410
    Abstract: A rotating agitational device, upon which is mounted a case (14) containing at least one lens and lens cleaning fluid, is electrically driven in a figure eight motion. This causes the contact or each lens to move about rapidly and clean itself automatically in a time of up to 60 seconds. The frequency of the agitations is between 10 and 100 Hz and is preferably between 35 and 45 Hz.
