    Abstract: Un verre ophtalmique multifocal (1) corrige la vue d'un porteur pour une première distance de vision dans une zone de vision principale (10) du verre, et pour au moins deux secondes distances de vision différentes dans une zone de vision secondaire (20) dudit verre. Pour cela, la zone de vision secondaire est divisée en au moins deux séries de régions alternées, qui produisent chacune une correction ophtalmique appropriée pour l'une des secondes distances de vision. Un porteur presbyte qui est équipé d'un tel verre peut aussi bien lire un livre que regarder un obstacle qui est au sol, pour une même direction de son regard à travers la zone de vision secondaire.

    Abstract: Une série de lentilles ophtalmiques progressives est proposée, qui est indexée par des valeurs d'addition de puissance optique de verres de lunettes à réaliser à partir de ces lentilles. Chaque lentille de la série détermine un écart supplémentaire entre une valeur de la puissance optique pour la direction de vision de près et une valeur maximale de la puissance optique qui est obtenue pour une direction de regard pointant en dessous de ladite direction de vision de près. Les lentilles de la série sont adaptées pour des postures de porteurs qui peuvent varier en fonction des valeurs d'addition de puissance optique.

    Abstract: Un procédé de réalisation d'un élément ophtalmique de correction d'amétropie, qui est adapté pour corriger les visions fovéale et périphérique d'un porteur, prend en compte les amplitudes de mouvements d'yeux et de tête dudit porteur. Une zone centrale de l'élément, dans laquelle la vision fovéale est corrigée, est dimensionnée par rapport à l'amplitude des mouvements d'yeux pour procurer un bon confort visuel. La vision périphérique est corrigée dans une zone périphérique de l'élément ophtalmique, pour éviter une augmentation à long terme de l'amétropie du porteur.

    Abstract: This method for predicting evolution over time of at least one vision-related parameter of at least one person includes: obtaining successive values for the person, respectively corresponding to repeated measurements over time of at least one parameter of a first predetermined type for the person; predicting by at least one processor the evolution over time of the vision-related parameter of the person from the obtained successive values for the person, by using a prediction model associated with a group of individuals; the predicting including associating at least part of the successive values for the person with the predicted evolution over time of the vision-related parameter of the person, the associating including jointly processing the successive values associated with the same parameter of the first predetermined type. The predicted evolution depends differentially on each of the jointly processed values.
