FR2957261A1 - Device for cleaning and sterilizing contact lenses, has receptacle whose contact lens case is provided with two compartments, where each compartment contains lens and filled with cleaning product at half portion of its capacity - Google Patents

Abstract

The device has a swivel lever (1) whose axle (2) is suspended by its ends with two supports (3). A magnet (4) is arranged in-line with a swivel lever. An electromagnet (5) is supplied with power using four LR6 batteries (6) of 1.5 V found under the magnet, at a distance of 1 mm. A receptacle (7) is arranged above the magnet, and comprising a contact lens case provided with two compartments, where each compartment contains a lens and filled with cleaning product at the half portion of its capacity.

Description

Being a wearer of contact lenses, rigid and flexible, for 31 years (1979), I had plenty of time to experiment with the use, cleaning and maintenance of these. I know the difficulties that a wearer of lenses encounters: the establishment on the eye which is not always easy, wearing during the day with tingling, itching and sliding, semi-opaque vision periods. And at the end of the day the removal of the lenses, the cleaning by massaging them, inside and outside, in the hollow of the hand, rinsing, putting in place in the case. We also know that after more than 30 years of mass marketing contact lenses, several manufacturers have created cleaning and decontamination products that are generally quite well studied. But for lens wearers, the problem remains unchanged: always manual cleaning and sterilization, with low efficiency to eliminate fouling, protein deposition, and therefore the accumulation of microorganisms. The invention relates to a device for cleaning and sterilizing contact lenses by mechanical movement back and forth, using the usual cleaning products, without distinction of mark or composition. The best method for the decontamination and cleaning of contact lenses is the mechanical movement of the two-compartment case filled with product at half capacity, containing one lens each. There is no better alternative, this method largely avoids the deterioration of the quality of the material and the optical quality of the lenses, unlike manual cleaning processes. This device consists of a rocker (1) whose axis (2) is suspended by its ends to two vertical supports (3). At the beam of the pendulum (1) is placed a magnet (4) 20 mm in diameter. Below the magnet (4), at a distance of 1 mm, is an electromagnet (5) powered by four 1.5V LR6 batteries (6). Above the magnet (4) is a rectangular receptacle (7) adapted to the contact lens cases. It is enough to give the first impulse to the pendulum so that it begins its movement back and forth, using the kinetic energy of the swing and the effect of the electromagnet to drive the case and its contents (product maintenance and lenses). With each swing, the product and the lenses are brewed, and it is this brewing movement that cleans and decontaminates. The wearer leaves his case containing his lenses on the device in motion for 6, 8, 10 hours, or more. At the end of the cleaning cycle, the wearer removes his lenses from the holster and places them on his eyes. His first impression: a great comfort of use, which usually extends until the end of the day. For the rest, he realizes the following: 2 2957261 - better hygiene; - no tedious cleaning by hand; - no wasted time, no fatigue; - lens economy (lenses last longer); 5 - product economy (decrease in product consumption). In conclusion, the invention is based on the creation of a movement which may also be that of an oscillation, a rotation, or a swing as can be seen in the attached diagram.
