You will love the London Clear Progressive. It has a rectangular shape that is favored by both men and women. This new progressive lens concept has never before been available in an over-the-counter priced eyeglass. It is amazing how well your eyes will adjust to the progressive lenses. They will work well for reading, computer work and over-the-desk distance. Many people need readers who do not need distance correction or perhaps just a bit of distance correction. These glasses are for that person! The London style comes in black and a few other options listed in the dropdown menu.. The frame has a spring hinge for a flexible fit. Frame Measurements: 5 1/8" x 1 3/4" (temple to temple x height of lens)
