Abstract

The glasses (1) has two non transparent lenses (12) supported by a frame (11) and a side piece (13). The lenses (12) are respectively provided with conical shaped through holes (121), where each hole has an outer side whose diameter is much larger than diameter of an inner side. The hole situated near circumference of each lens has much larger inclination angle than the holes situated in central part of the lens.

Description

traversants de forme conique situés le plus près du pourtour de laconical-shaped through-holes located closest to the perimeter of the

lentille ont un angle d'inclinaison plus grand sur un côté proche du pourtour de la lentille que les trous traversants de forme conique situés dans la partie centrale.  The lens has a larger tilt angle on a side near the periphery of the lens than the conically shaped through holes in the central portion.

L'invention sera mieux comprise à l'étude de la description détaillée d'un mode de réalisation pris à titre d'exemple non limitatif et illustré par les dessins annexés, sur lesquels : la Fig. 1 est une vue en perspective d'une paire de lunettes de correction d'astigmatisme selon la présente invention ; la Fig. 2 est une vue de dessus en coupe de la lentille de lunettes de correction d'astigmatisme selon la présente invention ; la Fig. 3 est une vue latérale en coupe de la lentille de lunettes de correction d'astigmatisme selon la présente invention ; la Fig. 4 est une première vue de dessus en coupe, partiellement agrandie, de la lentille de lunettes de correction d'astigmatisme selon la présente invention ; la Fig. 5 est une deuxième vue de dessus en coupe, partiellement agrandie, de la lentille de lunettes de correction d'astigmatisme selon la présente invention ; la Fig. 6 est une première vue latérale en coupe, partiellement agrandie, de la lentille de lunettes de correction d'astigmatisme selon la présente invention ; la Fig. 7 est une deuxième vue latérale en coupe, partiellement agrandie, de la lentille de lunettes de correction d'astigmatisme selon la présente invention ; la Fig. 8 est une vue en perspective d'une paire de lunettes avec les lentilles de correction d'astigmatisme selon la présente invention ; et la Fig. 9 est une vue en coupe d'une lentille de lunettes de correction d'astigmatisme selon la technique antérieure.  The invention will be better understood on studying the detailed description of an embodiment taken by way of nonlimiting example and illustrated by the appended drawings, in which: FIG. 1 is a perspective view of a pair of astigmatism correction spectacles according to the present invention; FIG. 2 is a sectional plan view of the astigmatism correction spectacle lens according to the present invention; FIG. 3 is a sectional side view of the astigmatism correction spectacle lens according to the present invention; FIG. 4 is a first partially enlarged sectional top view of the astigmatism-correcting spectacle lens according to the present invention; FIG. 5 is a second partially sectioned, partly enlarged, top view of the astigmatism-correcting spectacle lens according to the present invention; FIG. 6 is a first partially enlarged, sectional side view of the astigmatism-correcting spectacle lens according to the present invention; FIG. 7 is a second partially enlarged sectional side view of the astigmatism-correcting spectacle lens according to the present invention; FIG. 8 is a perspective view of a pair of spectacles with the astigmatism correction lenses according to the present invention; and FIG. 9 is a sectional view of an astigmatism correction eye lens according to the prior art.

Une forme préférée de lunettes de correction d'astigmatisme selon la présente invention, illustrée sur les figures 1, 2 et 3, comprend une monture 11 de lentilles, deux lentilles non transparentes 12 et deux branches 13 comme principaux éléments constitutifs assemblés les uns avec les autres. Les lentilles 12 sont respectivement pourvues d'une pluralité de trous traversants 121 de forme conique, qui ont respectivement, sur un côté extérieur, un diamètre plus grand que sur un côté intérieur. En outre, les trous traversants 121 de forme conique situés le plus près du pourtour de la lentille 12 sont pourvus d'un plus  A preferred form of astigmatism-correcting spectacles according to the present invention, illustrated in FIGS. 1, 2 and 3, comprises a lens mount 11, two non-transparent lenses 12 and two branches 13 as the main constituent elements assembled with each other. other. The lenses 12 are respectively provided with a plurality of conically shaped through-holes 121, which on one outer side, respectively, have a larger diameter than on an inner side. Furthermore, the conically shaped through holes 121 closest to the periphery of the lens 12 are provided with a further

3 grand angle d'inclinaison du côté proche du pourtour de la lentille 12 que ceux, 121, situés dans la partie centrale. Par conséquent, lorsqu'un utilisateur porte les lentilles de correction d'astigmatisme selon l'invention, l'utilisateur voit un objet extérieur à travers les lentilles 12 via les trous traversants 121 de forme conique, si bien qu'il ne se forme pas d'angles morts ni de zones sans visibilité pour la vue de l'utilisateur en raison de l'accroissement intensifié de la fonction de convergence des trous traversants 121 de forme conique. En comparaison des lunettes de correction d'astigmatisme selon la technique antérieure, les lunettes de correction d'astigmatisme selon l'invention comportent les deux lentilles pourvues des trous traversants de forme conique ayant un diamètre plus grand du côté extérieur que du côté intérieur, et les trous traversants de forme conique situés plus près du pourtour de la lentille ont un plus grand angle d'inclinaison du côté proche du pourtour de la lentille que ceux situés dans la partie centrale, si bien qu'il ne risque pas de se former d'angles morts ni de zones sans visibilité lorsque la personne voit à travers les lentilles des lunettes de correction d'astigmatisme selon l'invention, en raison de la meilleure fonction de convergence, les axes de vision de l'utilisateur n'étant pas gênés par les trous traversants grâce à la forme conique des trous traversants.20  3 wide angle of inclination of the side near the periphery of the lens 12 than those, 121, located in the central part. Consequently, when a user wears the astigmatism correction lenses according to the invention, the user sees an external object through the lenses 12 via the through holes 121 of conical shape, so that it does not form blind spots or blind areas for the view of the user due to the intensified increase in the convergence function of the through holes 121 of conical shape. In comparison with the prior art astigmatism-corrective spectacles, the astigmatism-correction spectacles according to the invention comprise the two lenses provided with the conically-shaped through-holes having a larger diameter on the outer side than on the inner side, and conical-shaped through holes located closer to the periphery of the lens have a larger angle of inclination on the near-lens side than those in the central portion, so that there is no risk of forming blind spots or blind areas when the person sees through the lenses of the astigmatism correction glasses according to the invention, because of the best convergence function, the axes of vision of the user not being hindered through the through holes due to the conical shape of the through holes.
