Because every face is unique, Bolle Safety has developed IRI-s, a model of universal safety spectacle that are ultra-modular and infinitely adaptable to every individual thanks to the B-Flex shape memory bridge. IRI-s is also available with dioptric corrective lenses. The +3 strength is only present in the d-shaped segment sat within the bottom part of the lens where typically a wearer would look through for help in reading. The remainder of the lens has no strength adjustment.
