The invention provides a tinted pair of lenses for overcoming the deleterious effects of nystagmic oscillations, particularly in persons suffering from dyslexia, the tinting varying along the lateral direction and extending in each lens over at least two zones, a lighter tint being used in a first zone extending from the lens edge 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 being used in a second zone extending over the remaining lens area.
