Abstract

The invention concerns a device for instantly correcting myopia, more particularly two devices for correcting the eyesight of short-sighted people and ensure a clear and comprehensive image vision. It consists firstly of a neutral contact lens (1) whereon a circle (2) is drawn in its centre whereof the circumference line (3) is clear and transparent. Secondly, in a neutral contact lens (1), at its centre, a small hole (2) is bored and set, and enclosed with a black circle (3). Said devices are particularly designed to correct myopia.

Invention description

This invention is a technology concerning the tradition of a neutral contact lens for a purely aesthetic purpose (neutral contact lens may be in color), consisting of applying to it a totally new method, simple in the immediate future to give myopic eyes a vision. 5 clear and detailed.

Currently, the existing means for correcting the view in the immediate future more or less satisfactorily are the corrective glasses, the corrective contact lenses, the surgery.

Totally new and revolutionary, this invention brings the same results as the already existing means on the planet. In fact, these are two techniques in one. The first technique, entirely new and quite simple in its character, consists of a small circle which is drawn on a transparent object. Acette technique of the circle, is given the name of "Artificial pupil Dossiaho chantai".

to 5 Now, when the artificial pupil is applied to the traditional neutral contact lens, centered on the lens, the result is the "LENS WITH ARTIFICIAL PUPIL" .D.C

The second technique consists of a hole through which one looks at a transparent object, the hole must be surrounded by a black circle. This technique applied to the neutral contact lens (only to use strictly the rigid lenses), gives the lens with artificial pupil DCAccording to the embodiment.

Take a traditional neutral contact lens in thick brown color or preferably, disposable soft lenses will do just fine.

Draw on the lens in the center, centered in the middle.

Z 010602 a card. If necessary, the dimensions of the artificial pupil, that is to say those of the circle drawn on the lens, must be equal to the dimensions of the natural pupil and the artificial pupil must be superimposed on the natural pupil through the contact lens.

The circumference line should be black. · The black of the line should be clear, transparent, barely drawn, even to the trace. The set is placed on the cornea so that the artificial pupil is superimposed on the natural pupil through the contact lens. With regard to the artificial pupil with hole, to use only and strictly the contact lens stiff neutral color brown.

Drill a small hole in the center of the neutral contactrigide lens.

Draw around the hole a circle whose circumferential line is dark black this time. The assembly is placed on the cornea of tello so that the artificial pupil is superimposed on the natural pupil through the contact lens. The main axis of the eye which crosses at once the yellow spot, the crystalline lens, the natural pupil also passes through the central point of the artificial pupil circle and hole.

The attached drawings illustrating the invention:

Figure (1) shows in section, the first device accordingin the invention.

FIG. 2 represents in section, the second device according to the invention. 30

FIG. 3 shows in section, the first principle applied in the invention. FIG. 4 represents, in section, the second principle applied in the invention. Referring to these drawings, the first device shown in FIG. 1 comprises a contact lens - neutral in color, of brown color (1), in the center of which is drawn a circle (2) of 4 mm or 4 mm. , 5 mm in diameter »The line of the circumference of the circle (3) is black in color and must be 2 mm wide. The black line of the circumference of the circle must be inevitable and indispensably clear, transparent it barely drawn, almost in trace, but absolutely visible and present

Figure 2 also shows a contact lens in color, brown in color (1) but this time the lens to be used must be indispensable and inevitably rigid. It is pierced with a hole (2) at its center, 1mm in diameter around which we draw a circle whose letra of the circumferential (3) is cotte time of a dark black and largo 3mm. From the hole must be missing any roughness .11 Must be clean and clean. In fact with regard to the artificial pupils of the circle and the hole, if necessary, the dimensions of the artificial pupils circle and hole must be equal to the dimensions of the natural pupil, and the artificial pupils must be superimposed on the natural pupil through of the lens. However, the dimensions may vary according to the precise need.

FIG. 3 represents the principle that has been applied in the device of FIG. 1. This principle consists in that on every trasparent object t (1), a small circle (2) of 1mm in diameter is drawn whose circumference of Ιει circumference ( 3) is 5 mm wide and dark black. 30 4 010602

In the case of the colorless brown contact lens (1), the circle (2) has a diameter of 4 mm or 4 mm, and the circumference of the circumference (3). is black, transparent almost to the trace but very visible and present. It is 2 mm wide.

FIG. 4 represents the principle that has been applied in the device of FIG. 2. This principle assumes that in every other object a small hole (2) of about 1 mm diameter is pierced around which a circle is drawn whose outline circumference (3) is dark dark and 5 mm wide.

In the case of the color-neutral, solid brown contact lens (1), the outline of the circumference (1) surrounding the small hole (2) is 3 mm wide. These devices according to the invention are particularly intended, to correct the lack of vision, myopia, in the immediate future.

Claims (1)

1 °) Device serving as an artificial pupil for correcting myopia, characterized in that: a) on a transparent object (1) a circle (2) of about 1 mm in diameter and whose circumference line ( 3) is dark black and 5 mm wide. b) according to another embodiment in a transpansparent object (1), a small hole (2) is drilled around which the black circle (3) is drawn and found, the line of the mférenco wax being 5 mm wide. 2 °) Device according to revendica; ion 1 characterized in that the center of a neutral contact lens, colormarron (l), is drawn a circle (2) of diameter 4 mm or 4.5 mm; the trait of the circumference (3) which is dark black, 2 mm wide, becomes on the lens clear, transparent, to painadine, almost to trace but visible and well present. 3) Device according to claim 1 characterized in that in the center of a neutral contact lens rigid, do color (1), do brown, it pierces a small trnu (2) diameter1mm; around the hole, one rins-dna a dark black cmuln (3) lnrijude 3 mm.
