Spectacle lenses for the prevention of myopia in children of risk group, having an asymmetric horizontal progression. The Central refraction range is from 0.0 V to +0.75 D with a cylinder up to 6D. The design feature of the lens is the progression on both sides of the optical center along the horizontal. The beginning of the progression is 6 mm. in the nasal side from the optical center and 4 mm. in the temporal side, respectively. The progression is saturated in 25mm from the optical center to both the nasal and temporal sides. The value of the nasal progression is 2.0 D, the temporal progression is 2.5 D.
