Definitions

  • Myopia commonly referred to as “near-sightedness”, is a progressive eye disease with a high and increasing incidence. Myopia involves refractive error usually caused by the eyeball growing too long such that images created by the lens focus in front of, rather than on, the retina, which can cause objects far away from the eye to appear blurry. A visualization of this process is illustrated in Fig. 1 .
  • lens designs have been studied and shown to potential effectiveness for myopia control.
  • Such lens designs include multifocal (e.g., bifocal, trifocal) and aspheric lens optics.

Abstract

L'invention concerne une lentille ophtalmique sélective en longueur d'onde qui utilise la coloration ou la teinte pour filtrer des longueurs d'onde sélectives et fournir ainsi un traitement de diverses conditions. Une lentille de base d'une première puissance de correction peut comprendre une pluralité de petites lentilles surélevées sur sa surface, chacune des petites lentilles étant d'une seconde puissance de correction qui est différente de la première puissance de correction. La coloration ou la teinte peut être appliquée à une ou plusieurs des petites lentilles disposées sur la lentille de base. La coloration ou la teinte peut être appliquée à la lentille de base, à un stratifié appliqué à la lentille de base, ou aux petites lentilles elles-mêmes. La coloration peut être appliquée à l'aide de colorants, de pigments ou analogues. Divers motifs de petites lentilles colorées ou teintées peuvent être utilisés, y compris des motifs formant des anneaux concentriques ou analogues.
