Abstract (en)

[origin: WO2006003275A1] The invention concerns an ophthalmic lens having a complex surface, with a substantially umbilic meridian and an average sphere progression ranging between 0.50 diopter and 0.75 diopter. The lens is prescribed for esophoric and non-presbyopic users. The lens is prescribed as a standard unifocal lens. Through the presence of the average sphere progression, the user is less adapted to near vision, thus compensating for his/her esophoria.
