Title
(EN) CONTACT LENS
(FR) LENTILLE DE CONTACT
Abstract
(EN)
Contact lens (10) that, during use, creates a hollow space between its concave internal surface and the convex external surface of the eye and contacts the corneal epithelium only for a fraction of its internal surface facing toward the eye thanks to the presence of a plurality of micro-protuberances (13) which allow to raise the contact lens (10) by a few micrometers with respect to the corneal surface.
(FR)
Lentille de contact (10) qui, pendant l'utilisation, crée un espace creux entre sa surface interne concave et la surface externe convexe de l'oeil et vient en contact avec l'épithélium cornéen uniquement pour une fraction de sa surface interne tournée vers l'oeil grâce à la présence d'une pluralité de micro-protubérances (13) qui permettent de soulever la lentille de contact (10) de quelques micromètres par rapport à la surface cornéenne.
