The Bloc Viper Junior sunglasses. Maintaining both the inherent properties and exacting standards of manufacture as Bloc Classics, Bloc Sports Frames utilise an 8 based curve to provide a natural close cranial fit and thus helping to eliminate the vortex of wind which can be so disconcerting during high speed pursuits. The 8 based curve also dramatically improves peripheral vision. The frames are further reinforced in areas of stress and fitted with integral sports hinges to increase strength, flexibility & durability. Following polishing, cleansing and painting, frames are fitted with soft rubber nose pads to assist facial grip without the uncomfortable cranial pressure often associated with some other brands.
