Multi-Focal Progressive Reading Glasses B016

These lightweight, comfortable and fashionable multi-focal progressive reading glasses feature sturdy hypoallergenic acetate frames, metal screwed hinges, and crystal-clear acrylic lenses at a price that won't break the bank. What Are Progressive Multi-Focal Lenses? While standard magnified reading glasses have a single prescription strength for near-vision across the whole lens, progressive multi-focal lenses have a near-vision section only in the bottom 40% of the lens while the upper section of the lens has no magnification power. Between the two sections is an 8mm wide transitional zone where the magnifying lower section blends into the non-magnified upper section, providing a degree of intermediate distance assistance. The magnification power shown is the power of the near-vision (reading) section of the lens. The upper section of the lens is not magnified.
