DEF

The radius of curvature at the apex of an aspheric surface having a sagittal depth that is approximately equal to the sagittal depth of the aspheric surface in a small area surrounding its apex.

OBS

apical radius of curvature: term used to describe contact lenses.

OBS

Glasses and contact lenses are considered to be either visual orthotic devices or visual prosthetic devices.

OBS

apical radius of curvature: term and definition standardized by the International Organization for Standardization (ISO) in 2006.

DEF

Rayon de courbure au sommet d'une surface asphérique ayant une profondeur sagittale approximativement égale à la profondeur sagittale de la surface asphérique dans une petite aire entourant son sommet.

OBS

angle de courbure apical : terme utilisé pour décrire des lentilles de contact.

OBS

Les lunettes et les lentilles de contact sont considérées comme étant soit des orthèses visuelles, soit des prothèses visuelles.

English

Subject field(s)
  • Orthoses
  • Prostheses
  • The Eye
DEF

The radius of curvature in the sagittal plane at a specified off-axis point on the surface.

OBS

The radius at a specified point on the surface is equal to the distance along the normal at that point to its intersection with the axis of rotation. The sagittal plane contains the normal to the surface at the specified point, but does not contain the axis of rotation, being perpendicular to the tangential plane.

OBS

Glasses and contact lenses are considered to be either visual orthotic devices or visual prosthetic devices.

OBS

sagittal radius of curvature : term and definition standardized by the International Organization for Standardization(ISO).

French

  • Orthèses
  • Prothèses
  • Oeil
DEF

Rayon de courbure dans le plan sagittal en un point, hors axe, spécifié sur une surface.

OBS

Le rayon à un point spécifié de la surface est égal à la distance le long de la perpendiculaire séparant ce point de l'intersection avec l'axe de rotation. Le plan sagittal est le plan contenant la perpendiculaire à la surface en un point spécifié mais ne contenant pas l'axe de rotation, étant perpendiculaire au plan tangent.

OBS

Les lunettes et les lentilles de contact sont considérées comme étant soit des orthèses visuelles, soit des prothèses visuelles.

OBS

rayon de courbure sagittal : terme et définition normalisés par l'Organisation internationale de normalisation (ISO).
