DEVICE AND METHOD FOR FACILITATING THE IDENTIFICATION FROM A DISTANCE OF PREFERRED RETINAL LOCI (PRLS) AND THE ECCENTRIC FIXATION

摘要

Lens for people having a visual deficit in one or both the eyes comprising at least one magnifying portion and at least one prismatic portion with a predetermined prismatic element and a predetermined orientation, which orientation corresponds to an angle of rotation or of positioning of said prismatic element about an axis of rotation. Said prismatic element is rotated and/or rotatable by a predetermined angle about an axis of rotation, which axis of rotation is parallel and/or coincident with the axis perpendicular to the anatomical frontal plane of said lens, said angle being defined on the basis of the position of the eccentric preferred retinal locus (PRL) (31) within the parafoveal region in order to facilitate image fixation on said area.
