Flip-up Clip-Mags Clip-on Magnifiers turn prescription eyewear and most safety glasses into "reading-style" magnifiers with versatile, broad-range magnification. Frameless, flush-fitting optics combine a long depth-of-field with unobstructed bifocal vision. Exceptionally lightweight optical polycarbonate lenses flip up and stay out of sight when not being used. Non-slip tips protect glasses from scratches. Includes protective carrying case. Available in 1.5X, 2.0X, or 2.5X magnification powers.
