Disclosed is a single focus compound lens and a mold for manufacturing the single focus compound lens, where the single focus compound lens has a reading far point diopter lens and a reading near point diopter having different diopters that are integrally molded to have the same optical central point and the mold has the two divided areas with respect to the optical central point, each of the two areas forming an inner peripheral surface having a difference in curvature and thickness corresponding to the diopter difference, such that near distance works like reading or doing with a computer can be accomplished without any trouble and the fatigue of eyes caused due to the failure of correspondence of focuses can be prevented.

L'invention concerne une combinaison de lentilles à foyer unique et un moule de fabrication de la combinaison de lentilles à foyer unique, la combinaison de lentilles à foyer unique présentant une lentille de correction dioptrique punctum remotum et un dioptre punctum proximum de lecture présentant des dioptres différents qui sont moulés solidaires par construction de manière à présenter le même point optique central, le moule présentant les deux zones divisées par rapport au point optique central, chacune des deux zones formant une surface périphérique intérieure présentant une différence de courbure et d'épaisseur correspondant à la différence dioptrique, de sorte que les travaux de proche distance tels que la lecture ou le travail avec un ordinateur peuvent être effectués sans aucun trouble et la fatigue des yeux entraînée par la non correspondance de foyers peut être empêchée.
