Abstract (en)
[origin: WO0184213A2] The invention relates to a spectacle lens comprising: an area intended for looking at far distances and especially ad infinitum (far part); an area intended for looking at near distances and especially reading distances (near part), and a progression area located between the far part and the near part, in which the effect of the spectacle lens increases from the value of the distant reference point situated in the far part to the value of the near reference point situated in the near part along a curve (main line) that bends towards the nose. The invention is characterized, inter alia, in that the deviation (the difference between the maximum and minimum value occurring during the movement) of the binocular imaging properties while a moving object is being followed lies below a physiologically predetermined limit with the purpose of minimizing alteration of the binocular imaging properties during horizontal eye movements.
