Lenz is an innovative durable transparent device that when placed over your reading page will reduce reading eye strain and in some cases headaches when reading in bright lights or the Sun. It is the same on both sides.
Simply place your choice of Lenzcolor over the page you are reading then read through it as shown.
Lenz is a durable, lightweight, waterproof product. Not only is Lenz a great filler gift for those who love to read but also for the practical reader who needs to bulk read for college or a professional who spend the bulk of their day and night reading.
