In a tinted pair of lenses (10, 10') for overcoming the deleterious effects of nystagmic oscillations, particularly in persons suffering from dyslexia, the tinting varies along the lateral direction and extends in each lens over at least two zones (12, 14). A lighter tint is used in a first zone (12) extending from the lens edge (16) nearest to the nose of the wearer, when the lens is in use, to a position corresponding to the centre of the pupil, and a darker tint is used in a second zone (14) extending over the remaining lens area. <IMAGE> |
