" LUNETTES DE EROTjSC#IOH D4S YLUX CONTRE LES BAYONS NOCIFiJ."
Le brevet principal n 619.040 est basé sur l'utilisation de lunettes dont les verres de protection sont constitués d'une partie claire et d'une partie teintée dont la ligne de séparation nettement délimitée passe exactement en face du centre de la pu- -pille de l'oeil concerné.
Lors de nombreux essais pratiques effectuée avec Les nou- -velles lunettes, l'inventeur a constaté qu'une certaine possibi- -lité de gêne pour l'utilisateur pouvait résulter de l'éventuelle existence de rayons lumineux émanant de sources situées nettement sous le plan horizontal de vision( par exemple, lors de larêver- -bération des rayons solaires sur le capot d'une automobile).
Cet inconvénient peut se supprimer grâce au placenent, sur les verrec, d'une seconde partie teintée, également arec li- -gne de séparation nettement délimitée, disposée dans la partie inférieure des verres. L'expérience a démontré que le meilleur effet s'obtenait lorsque cette seconde partie, touchant la pre- -mière du côté de la branche de la lunette, s'écartait pregres- -sivement de cette première partie, tout en présentant un) conca-

-vité tournée vers le haut et de tracé sensiblement en arc de oer- -cle.
Le dessin annexe représente, à titre exemplatif et non limitatif, une paire de lunettes réalisée conformément à l'inven- -tion.
Dans cette figure, les numéros de référence 1 à 7 repré- -sentent les mêmes éléments que dans le brevet principal, tandis que le 8 désigne la nouvelle partie inférieure teintée dont le rebord 9 de séparation d'avec la partie claire 2 eat net et our- -viligne. On voit que les deux parties teintées se touchent en 10 et divergent progressivement.

"EROTjSC # IOH D4S YLUX GLASSES AGAINST NOCIFiJ BAY."
Principal Patent No. 619,040 is based on the use of spectacles whose protective lenses consist of a clear part and a tinted part of which the clearly defined separation line passes exactly in front of the center of the pupil. of the affected eye.
During numerous practical tests carried out with the new glasses, the inventor observed that a certain possibility of discomfort for the user could result from the possible existence of light rays emanating from sources located clearly under the lens. horizontal plane of vision (for example, when dreaming of sunlight on the hood of an automobile).
This drawback can be eliminated thanks to the placement, on the glasses, of a second tinted part, also arec li- clearly defined separation -gne, arranged in the lower part of the glasses. Experience has shown that the best effect is obtained when this second part, touching the first on the side of the branch of the telescope, deviates pregres- -sively from this first part, while presenting a) conca -

-vity facing upwards and with a substantially circular arc layout.
The accompanying drawing represents, by way of example and without limitation, a pair of glasses produced in accordance with the invention.
In this figure, the reference numbers 1 to 7 represent the same elements as in the main patent, while the 8 designates the new tinted lower part of which the rim 9 separating from the light part 2 is clean and our- -viligne. We see that the two tinted parts touch at 10 and gradually diverge.
