TECHNICAL SPECIFICATIONS From 40 to 45 years of age, the eye is subject to presbyopia, a natural phenomenon linked to aging, which results in a decrease in vision when reading closely. This decrease in the accommodative function of the lens, leads to an increasing difficulty in focusing on nearby objects and, if not corrected, can lead to headaches and eye burns. TWIG® reading glasses are specially made to facilitate the normal functioning of the eye and restore visual acuity reduced by presbyopia. In addition, thanks to the flex rods equipped with a spring mechanism, they are comfortable and light, adapting perfectly to any type of face. ✓ Model: TWIG® Grieg ✓ Gender: Unisex ✓ Frame: Added polycarbonate ✓ Lenses: Polycarbonate ✓ Type: Reading ✓ TWIG® package
