Abstract:
1. An ophthalmic lens comprising on its surface, a first, central, zone having a transmission of less than 50% in the short wavelength range comprised between 400 nm and 480 nm, and a transmission of greater than 50% in the long wavelength range comprised between 480 nm and 700 nm, and a second, peripheral, zone having a transmission of greater than 50% in the short wavelength range comprised between 400 nm and 500 nm, and a transmission of less than 50% in the long wavelength range comprised between 500 nm and 700 nm, wherein the ophthalmic lens is a progressive corrective ophthalmic lens with a far vision optical centre and a near vision optical centre, the central zone essentially covering the zone around the far vision optical centre and the zone around the near vision optical centre, as well as a band linking these two zones and corresponding to the path followed by the eye when it passes from one to the other, and the diameter or the largest dimension of the central zone covering the far vision optical centre is comprised between 5 and 35 mm, preferably between 10 and 25 mm, and is in particular approximately 20 mm, the diameter or the largest dimension of the central zone covering the near vision optical centre is comprised between 5 and 15 mm, preferably between 7 and 13 mm, and is in particular approximately 10 mm, and the width of the band linking these two zones is comprised between 3 and 7 mm.
