This product for the visually impaired allows you to take advantage of today's modern cell phones. It's also known as a Phone Monocle because it enlarges the display on a cell phone as if you were looking at it through a monocle. A 2X lens is framed in rubber and a flexible band fits around just about any size cell phone. Since the band stretches, it even fits on many portable phones. Not only does the lens increase the size of the letters by about 2 times, but the rubber frame and band makes it easier to hold onto the cell phone. The Phone Monocle is an affordable and unique low vision aid. The lens measures approx. 1" X 1.5". The solid frame measures approx. 1.5" X 1.75" and the rest is a stretchy translucent rubber band-like material.
