Special spectacle lens for forming sunglasses, has one horizontal bending radius and different vertical bending radii on one of its inner and outer surfaces, where exterior convexity of lens near temporal side is more bent than nasal side

摘要

The lens (1) has single horizontal bending radius and different vertical bending radii on one of its inner and outer surfaces. The ranges of variation of each vertical bending radius and horizontal bending radius are between -10 millimeter (mm) and 10 mm and between -15 mm and 15 mm, respectively. The lens has exterior convexity near the temporal side, where the convexity is more bent than the nasal side.
