Designed and constructed with the same rigorous standards and high-quality components and materials as our GuideLine Pro Series, GuideLine Bifocals are equipped with an additional magnifying feature - nealy imperceptible to others - to compensate for the farsighted water-sportsman.
A small magnifying lens inset into the lower third of the surrounding polycarbonate lens allows the wearer to adjust instantly from seeing clearly up close to far in distance.
Award-winning Guideline brand bifocals are the best product of its kind on the market today!
Mantis Bifocal
With its progressive-looking brushed aluminum-and-magnesium semi-rimless composite
frame, no one will suspect a bifocal lens is hiding in such a sporty sunglass.
Like the non-bifocal Mantis, the Mantis Bifocal includes spring hinges, rubber temple tips and adjustable nose pads.
