Definitions

  • THIS INVENTION relates to spectacles.
  • Spectacles are known, as so-called “sun glasses” which have lenses (normally plain lenses) provided with a partially reflective and partially light transmissive layer or coating, whereby the intensity of light passing to the wearer's eyes through said layer is attenuated without otherwise interfering with the wearer's vision, whereas, due to the relatively high level of light reflected outwardly from the partially reflective, partially transmissive layer, as compared with the inten ⁇ sity of light reflected from the wearer's skin and eyes through the partially reflective and partially trans ⁇ missive layer, the lenses present the appearance, to a person viewing the wearer, of totally reflective metallic surfaces.
  • spec ⁇ tacles having lenses (as herein defined) each provided with a partially reflective and partially light transmissive layer which incorporates a hologram, whereby a holographic image within the area of the lens may be viewed by a person looking at the wearer of the spectacles.
  • a spectacle frame provided with a light reflective coating by sputtering with metal.
  • lens as used herein is intended to com ⁇ prehend a transparent body without any converging or diverging power, as well as a body which acts as a con ⁇ verging or diverging lens.
  • spectacles as used herein is also intended to include, in addition to spec- tacles of conventional construction, Items such as "clip on” attachments intended as an ancillary to normal spec ⁇ tacles and which may be clipped over the frames of the latter in known manner to cover the normal lenses with additional "lenses".
  • the term is also intended to include variants where, for example, a single unitary transparent body extends across both eyes and thus serves as the "lenses".
  • a pair of "sun glasses” has lenses of transparent material hav ⁇ ing a layer or coating which is partially reflective and partially light transmissive, with the optical density of said layer or coating being varied locally in accordance with the patterning of a hologram in a manner known per s_e, so that a person viewing the lenses of the spectacles whilst worn by another person will be able to view, with ⁇ in the areas of the lenses, a corresponding holographic image.
  • the image concerned may be, for example, that of a large caricatured eye-ball winking, that of a flag such as the Union Jack, or advertising material, for example pertaining to a product in the promotion of which the spectacles in question may be sold or given away.
  • the said layer when provided, may comprise a plastics material film which has been sputtered with metal.
  • reflective metals which are silver or gold in appearance may be used. In practice, silver, gold or aluminium metals are likely to be used.
  • the lenses, with the hologram-incorporating, reflective/transmissive layer may be arranged to be interchangeable in the spectacle frame so that the wearer can present to onlookers selected hologram images from a plurality of available images and may change the lenses, and thus the images, from time to time, as desired.
  • the sputtering technique referred to above particularly in conjunction with the use of relief image holograms, as set out below, allows the production of sunglasses such that it will not be apparent to the person wearing the sunglasses that there is a hologram incorporated in or on the lenses, nor will there be any other impediment to clear vision.
  • the invention provides a medium of sub- stantial potential for advertising and the like, as it is likely that members of the public will be willing to pay at least as much for such spectacles incorporating holo- -I -
  • the spectacle lenses are of glass
  • the hologram is provided thereon in the form of a relief image hologram on one surface of the glass, formed by ion bombardment and acid etching of the glass, with the subsequent application of a part-transmissive, part-reflective coating on the re ⁇ sultant undulating surface.
  • the coating may be formed by sputtering with an appropriate metal, such as gold, silver or aluminium.
  • the spectacle lenses may, however, be made from plastics by injection moulding or by pressing, the holo ⁇ gram taking the form of a relief image hologram impressed upon the respective lens surface by nickel press master, the lenses thereafter having a part-transmissive, part- reflective coating applied thereto, for example by metallic sputtering as set out above.
  • a photo-polymer is used, to which the hologram pattern is applied photo ⁇ graphically, and which is subjected to "developing" pro- cedures, known per se, to form the relief image hologram thereon and which thereafter forms a basis for the pro ⁇ duction, in manner also known per se, such as by an electrolyte process, for the production of the nickel master.
  • the arrangement in any of the above embodiments, is such that the person wearing the spectacles does not perceive the holographic image, but has the same view as he would if he were wearing ordinary "sun-glasses". That is to say, the sunglasses, apart from the desired reduction in light intensity, present no impediment to the vision of the wearer.
  • the sur ⁇ faces of the lenses are preferably curved, in the con ⁇ ventional manner, but may, of course, be plane if pre ⁇ ferred.
  • spectacle frames may be made of plastics, in a manner known per se and may subsequently, before being fitted with lenses, be metallised by sputtering with metal. Alternatively, lenses already fitted may be appropriately masked off during sputtering the frames. Ideally, reflective metals which are silver or gold in appearance may be used, for example silver, gold or aluminium metals may be used.
  • multi-layer coating of the spectacle frames may be carried out by subjecting the frames to successive coating steps, and that sputtered metal layers may be utilised in conjunction with non- metallic layers, for example a transparent layer, such as a tin oxide layer may be applied over a sputtered metal layer or alternate layers of various metals and tin oxide may be applied to the frames. It may be found advant- ageous to similarly multi-coat the hologram-bearing spectacle lenses.
  • the sputtering may, if desired, be confined to specific areas on the frames, to afford special visual effects.
  • the optical density of the metallic coating on the frames may be varied locally in accordance with the patterning of a transmission hologram or diffraction grating in a manner known per se, so that a person viewing the frames of the spectacles will see holographic images associated therewith, or vividly coloured patterns or the like, with or without a "three- dimensional" effect.
  • the frames of the present invention may be used in conjunction with lenses bearing holograms, as proposed above.
  • the sputtering of the frames in accordance with the present invention allows excellent visual coordination of the frames with the lenses, so that the frames can be made to merge visually with the lenses or can be contrasted therewith according to the wish of the designer, rather than by necessity.
  • the present invention is equally applic ⁇ able to spectacles having conventional lenses.
  • the holograms thereon may be provided as relief image holo ⁇ grams in moulding the spectacle frames, by the technique referred to above for producing lenses bearing such holo ⁇ grams, with subsequent application of a reflective coat- ing, for example, by metallic sputtering.

Abstract

Des lunettes, telles que des lunettes de soleil, comprennent des verres à réflexion et transmission partielles incorporant un hologramme. Il en résulte une image holographique à l'intérieur de la surface du verre, image qui peut être vue par une personne regardant le porteur des lunettes. Les verres, qui peuvent être en plastique, comportent un hologramme à image en relief qui est formé lors de leur moulage, lesdits verres étant ensuite métallisés par exemple par pulvérisation métallique. L'hologramme peut présenter l'apparence d'un globe oculaire clignant de l'oeuil, d'un drapeau, d'une publicité ou similaire.
