Bifocal Lenses (BL)


Blended bifocal lenses are also referred to as the invisible or seamless bifocal. This lens is designed to conceal the transition from the magnification segment to the distance segment. This is accomplished by placing a blended range of 1mm to 2mm between the segments. This range can distort perspective at times that some may not adapt to easily.
