Definitions

  • the invention relates to a device defined in the preamble of claim 1.
  • the known storage cases consist of a flat, opaque piece in which the recesses for the contact lenses are provided, which recesses are closed with a screw cap. Both hydrophilic and gas permeable contact lenses should be kept moist. When it dries out, a hydrophilic contact lens can be destroyed and a gas-permeable contact lens changes shape. The moist storage enables asepsis of the lens through antiseptic additives in the storage medium.
  • the object of the invention is at the same time to enable the contact lens to be stored and examined in the storage container.
  • the contact lens can be viewed or examined in transmitted light or with focal lighting.
  • the contact lenses have to be examined for deposits, microorganisms, fungi, mechanical damage and age changes which adversely affect their wearing comfort and their optical properties and can lead to eye complications.
  • organic and inorganic deposits form on the surfaces of the contact lenses and microorganisms and fungi are deposited.
  • the organic deposits are components (proteins, mucins, lipids) of the tear fluid.
  • the inorganic deposits (metal, iron, rust) come from work-related circumstances (air pollution, street dust, metal abrasion, etc.).
  • the inorganic deposits also include those of calcium salts, which are also referred to as hard water deposits. They arise as a result of rinsing the contact lenses with tap water or by changing the pH of the tear fluid (medication, physiological influences).
  • the microorganisms (bacteria, viruses) and fungi belong to the normal microflora of the conjunctiva, the conjunctival sac and the tear-evacuating pathways. This changes as soon as the balance of the microflora is disturbed, which happens due to the transmission of germs from hands, improper cleaning and disinfection, illness or metabolic disorders (diabetic) of the lens wearer or contact of the contact lenses with the environment. It is also known that the contact lenses are subject to changes, damage and aging to their material in the course of their use. The material changes (e.g. discoloration) are based on environmental influences (cigarette smoke, color vapors, cosmetics, discolouration of storage containers), aging and also normal cleaning measures. The damage (hairline cracks, abrasions, scratches, edge breakouts) are due to improper handling, drying out and cleaning of the lenses. These changes in the contact lenses cause a number of complications for the user or wearer.
  • US-A-4 545 479 proposes a device in which contact lenses can be stored and observed. Since there is no liquid and no fixation, the soft and hard contact lenses are dried out and damaged during storage due to unintentional movements in their housings. Because of the lack of fixation, the daily observations of the contact lenses are made more difficult by the fact that the contact lenses as a whole can only be observed at a certain position of the entire device. With any other device position, the contact lenses move in an unforeseeable manner out of the observation field, following the effect of gravity.
  • an external lighting source for example a punctiform light source or a window, against which the device for observing the contact lens is held, overlaps undesired contours with the image of the contact lens due to the optical structure of the device, which the significance of the observation worsen.
  • the observer cannot move between the rubbers or mechanical Differentiate damage on the contact lens surfaces and the undesired contours, e.g. light reflections.
  • GB-A-2 033 605 describes a device for centering contact lenses of different parameters in the position favorable for the optical examination.
  • a mechanical lever mechanism moves the contact lens provided in a liquid back and forth several times until its concave inner surface comes to rest on an examination window.
  • this contact takes place in a dry state, which under certain circumstances can lead to damage to the concave inner surface of the contact lens.
  • the device is not used to store contact lenses.
  • the object of the invention is to provide the contact lens user with an improved storage case and a simple examination device, the two devices being integrated in one piece.
  • the wearer is therefore able to examine his contact lenses during storage. This prevents the contact lenses from drying out, which leads to destruction.
  • the advantage of examining the contact lenses is that contamination, reflections and artifacts cannot occur.
  • the device shown in FIG. 1 contains a body 1 made of optically transparent material, in which two cavities 2 are provided for storing one contact lens per cavity. Each cavity is closed watertight by means of a cover 3 made of transparent material. A thread is preferably provided on the cavity and cover, so that the cover is screwed into the cavity. Another detachable connection is readily applicable, e.g. Bayonet or plug connection.
  • the bottom 21 of the cavity 2 is shaped like a paraboloid or a cone. As a result, a contact lens comes into contact with its convex side in such a way that there is only a line contact between it and the floor.
  • the lid 3 can only be screwed so deep into the cavity 2 that it does not necessarily touch the contact lens, but it limits its freedom of movement. This and with the linear support in the cavity ensure that all parts of the contact lens, including the edge, can be viewed without gaps.
  • a reservoir or container 4, 6 is provided.
  • One container 4 is attached in the edge zone of the body 1 and has a large volume for an aqueous solution. Such solutions are known as contact lens storage media.
  • the container 4 is in the immediate vicinity of the small chamber in which the contact lens is fixed.
  • the container 4 is circular. It can also be elliptical if the body has this shape.
  • the cavities 2, which are closed in a liquid-tight manner by the covers 3 and contain the contact lenses, are filled with liquid in the same way.
  • another container 6 can be arranged in the central zone of the body 1, which is shown in dashed lines.
  • the surrounding containers 4, 6 can communicate with the cavities 2 via communicating channels 7 and ensure that the contact lenses are adequately supplied with liquid.
  • the lid 3 screwed or inserted into the cavities has grooves or cutouts on its side so that the liquid container 4 or 6 can communicate with the cavities 2 via the channels 5 or 7 even when the lid exits the upper channel 5 or 7 should affect.
  • 1 shows a conical bevel in the lower part of the cover 3.
  • FIG. 2 shows the same things of FIG. 1 and better reflects the spatial arrangement of the liquid containers 4, 6 and the communicating channels 5, 7.
  • the edge zone of the body 1 shown is circular. However, it can also be elliptical or approximately square.
  • Four cavities 2 can also be provided, which have corresponding channels to the containers 4, 6.
  • the channels can also be arranged differently, as was shown in FIG. 2.
  • FIGS. 1 and 2 show the liquid containers 4, 6 which can supply the contact lenses in the cavities 2 with sufficient liquid.
  • New liquid can be brought into the container by directing the liquid into the cavities and through the channels 5, 7 or into a special filling opening 8 directly into the container.
  • the old liquid is replaced by the new one in the same way.
  • the storage fluid is usually exchanged daily.
  • the contact lenses stored in the cavities 2 can be examined or observed. This is done in such a way that the observer holds the cover 3 against a light source and looks at the underside 9 of the body 1.
  • the surface of the lid is matted, whereas the underside 9 of the body 1 is smooth and transparent.
  • the refractive indices of the optical transparent material of body 1, cover 3 and liquid in the cavity 2 should be in a narrow range, so that no undesirable refractions of the light rays can occur.
  • the matt finish of one surface should allow a uniformly illuminated background against which the contact lens can be viewed.
  • the image of the contact lens viewed against the frosted background can be magnified, e.g. a converging lens 10 are enlarged, which is glued to the correspondingly shaped surface 9 at the points close to the floors 21.
  • a converging lens 10 is drawn.
  • the converging lens has a larger diameter than the contact lens to be considered, so that the entire surface of the contact lens can be examined. It is also possible to glue a single large magnifying lens or converging lens 10 onto the entire surface 9. It is only necessary to ensure that the contact lens stored in the cavity 2 has a certain distance from the converging lens 10. At a distance smaller than the focal length of the lens, a virtual, enlarged image of the contact lens is created. A distance between the single and double lens focal length creates a real, enlarged image of the contact lens.
  • magnification optics or converging lens is arranged in or on the cover 3.
  • the cover 3 is smooth and the underside 9 of the body 1 is matted.
  • the contact lenses can also be used with so-called focal lighting, i.e. by means of a slit lamp.
  • the present combined device contact lenses can be stored and examined at the same time.
  • the device is inexpensive to manufacture and easy to use.
