Eurospec X Progressive No Line Bifocal

Expand your field of vision with ruggedly stylish Eurospec X Progressive No-Line Bifocal reading glasses. Featuring optical quality lenses that are correction-free at the top with gradually increasing magnification toward the bottom, you can wear these glasses all day and see well at a distance, up close, and in between. The almost weightless semi-rimless metal frame has hidden spring hinges and silicone nose pads for a flexible, comfortable fit. A companion hard case and micro-fiber cleaning cloth are included with each pair. Your New "No Line" Lenses, also known as Progressive Lenses, will provide a clear, comfortable close up vision, without a line of sight. The Upper portions of your lenses are clear. As you lower your eyes, the magnification increases gradually allowing you to see better at different close up distances. CR39 Optical resin. 1.50 index of refraction.
