## Background
1. Field of the invention

The present invention relates to an opthalmic apparatus for use to help a person having a poor vision, to proceed adequately to make-up her eyes.

2. Description of the prior art

A major problem met by people, especially women having a poor vision is to make-up their eyes adequately. The problem affects most women over 45, and is also applicable to actors with faulty vision. To applicant's knowledge, the only solution that has been proposed to solve this problem is to provide make-up frames having opthalmic lenses pivotably mounted to free one eye and then the other during the make-up.

An object of the invention therefore lies in providing an apparatus suitable to solve the above problems. In principle, the invention lies in an apparatus which is capable of holding and adjusting a pair of lenses in front of a mirror, the lens prescription corresponding approximately or exactly to that required for eye-glass frame try-outs or for make-up.

More specifically, the invention provides an apparatus for holding a pair of lenses in front of a mirror, comprising: cross arm, and a pair of spaced-apart lens carriers mounted onto said cross-arm; eyes and support onto the mirror in such a manner that the opthalmic lenses lie in a common plane in front of, and parallel to, said mirror.

In accordance with a preferred embodiment of the invention, the lens carriers are straight bars projecting away from said cross arm in front of said mirror, said lenses being carried by said straight bars at the ends thereof away from said cross arm. Means may also be provided for adjusting the distance between said spaced lenses while holding said lenses in said common plane, said lens distance-adjusting means comprising means for mounting the lens carriers on said cross arm and allowing said carriers to be displaced lengthwise along the cross arm of said T-shaped member in order to adjust the distance between said lenses.

In accordance with another preferred embodiment of the invention, each one of said lens carriers is essentially a right-angular bar assembly comprising: and wherein said lens stands in said common plane and a second position wherein said second bar is pivoted out of said common plane.

The means for mounting the longitudinal arm of the T-shaped member onto the mirror preferably comprise a suction-cup device attachable to the mirror and including means for preventing said longitudinal arm from wobbling with respect to said mirror.

Other objects and advantages of the invention will become apparent to those skilled in the art from the following description having reference to the appended drawings.

FIG. 7 appearing on the same sheet of drawings as FIG. 5, is a side elevational view of another suction-cup device that can be used with the apparatus shown in FIG. 5.

The apparatus shown in FIGS. 1 to 4 is intended for use by a woman to make-up her eyes.

In this embodiment, the lens support 59 is located at the lower end of the mirror 7. It has a T-shaped structure and comprises a longitudinal arm 61 perpendicular to the mirror 7 and a cross arm 75 normal to the arm 61 and thus parallel to the mirror. The longitudinal arm 61 of the support slides through a hole 63 of the mirror 7 and its backing plate 13 as well as through a bore of a bearing block 65 fixed to the backing plate. The longitudinal arm 61 has, at that end, a flat 67 and a knob 68 is driven against it to hold the support 59 non-rotatably on the mirror and with the lenses 69 it supports at the appropriate distance from the mirror, this distance being adjustable in the same manner.

The lenses 69 are carried and held normally parallel to the mirror, by a pair of generally right-angular bar assemblies 71 each made up of a first straight bar 73 connected at one end to one end of the cross arm 75, and of a second straight bar 77 to the free end of which one lens 69 is secured. Since the apparatus is adapted for one particular person only, the prescription of the lenses may be exact and the second arm unremovably joined with the first arm 73.

For connecting the cross arm 75 and the first bars 73 together, the latter have transverse through holes 79, preferably in enlargements 81 thereof (FIG. 2). The cross arm 75 has end flats 83 parallel to the mirror 7 and slid across the holes 79. The bar assemblies 71 are secured to the cross arm 75 by set screws 85 that are applied against the flats 83 and clamp the assemblies 71 to the cross arm 75 with the second arm 77 and lenses 69 held parallel to the mirror 7.

The lower ends of the second bars 77 are each provided with a hinge 87 (FIG. 3) capable of allowing the two bars 77 and their lenses 69 to be moved between a first "normal" position, wherein the lenses 69 stand in their common plane and are essentially parallel to the mirror 7, and a second position wherein one of the two bars is pivoted out of the common plane toward the mirror, as is the case with the right-ward bar 77 and lens 69 in FIG. 1. The hinge 87 may be of the spring-ball type like the one known under the trade mark SFEROFLEX, capable of releasably locking in the aforesaid two position. With this arrangement, make-up of one eye can be achieved by folding the relevant lens 69 while looking into the mirror through the other lens.

In this case, the lenses 69 may be set into proper and final position by the dispensing optician himself for the specific person for whom the apparatus is adapted and the lenses are accordingly to the person's exact prescription, as aforesaid.

In order to afford as much space as possible between the bar assemblies 71 so that the user may freely position his face between them, the lenses 69 may be made narrow, rectangular and rounded edged, as shown, allowing the bar assemblies to be moved further apart while still permitting the same spacing between the lenses.

The apparatus shown in FIG. 5 is a variant of the one shown in FIG. 1. This variant is intended to be used by a woman who is accustomed to make-up her eyes in front of a given mirror inside her house or apartment and does not want to buy a whole kit as shown in FIG. 1.

In this embodiment, the lens support 59' has a T-shaped structure and comprises a longitudinal arm 61' and a cross-arm 75' normal to the arm 61. Instead of being slidally mounted into a hole provided in a mirror especially provided and designed for this purpose, the longitudinal arm 61' is detachably fixable on any mirror 7' by means of a suction-cup device 91 (as shown in FIG. 7) or 91' (as shown in FIGS. 6a and 6b), acting as lens support mounting means.

The longitudinal arm 61' has at its "free" end, a flat 67'. A knob 93 (or 93') intersects a longitudinal hole 95 (or 95') provided in a bearing block 97 (or 97') forming part of the device 91 (or 91'). This knob is driven against this flat 67' to fix non-rotatably the support 59' on the mirror 71 with the lenses 69' it supports at a predetermined but not adjustable distance from the mirror.

The lenses 69' are carried and held normally parallel to the mirror by a pair of generally right-angular bar assembly 71' similar is structure, operation and use to those shown in FIG. 1, except that their first straight bars 73' integrally extend from the opposite ends of the cross bar 75' and they are not laterally adjustable with respect to each other.

Of course, the width between the lenses 69' must be predetermined to fit a great majority of people, or to be adapted to every prescription, as are the opthalmic lenses per se.

As shown in FIG. 7, the suction-cup device 91 may comprise a suction-cup 99 made of rubber material, that is centraly fixed to a rigid threaded peg 101 integrally projecting from the block 97 opposite to the hole 95. To prevent the longitudinal arm 61' and thus the support 59' and lenses 99, from wobbling, use can be made of means consisting of a small, funnel-shaped body 103 of rigid plastic having a cylindrical portion 105 slidably mounted onto the peg 101 and a conical portion 107 whose larger base 109 is sized to bar onto the mirror outwardly of the suction cup 99 and thus "stabilize" the device 91 and support 59' connected thereto. A nut is screwed on the threaded peg 101 to lock the same relative to the body 103 and thus keep the suction-cup 99 in fixing position.

As shown in FIGS. 6a and 6b, the suction-cup device 91' may alternatively comprise a suction-cup 99' made of rubber, that is centrally fixed to a short arm 102' pivotably mounted at the end of a peg 101' integrally projecting from the block 97' opposite to the hole 95'.

The cup is covered by a rigid plastic cap 103' which is designed to be pushed against the mirror by some camming effect when the block 97' and peg 101' are moved from the position shown in FIG. 10a to the one shown in FIG. 10b. This structure and the way it works to prevent wobbling are already known in the act and have not to be disclosed in further detailed.

In all cases, the use of such suction-cups devices 91, 91' makes it possible to fix the support 59' and its attached lenses 69' to any mirror, thereby making the "kit" useful without having to buy and/or use a built-in mirror as shown in FIGS. 1 to 4.
