Contrast Viewer Set

$ 8.99 Sale

These adorably shaped red and green contrast viewers work as a filter to allow you to see how fabric contrasts more easily. Everything you view through these lenses takes on a black and white effect (a.k.a. greyscale), with the contrast viewer's color applied to it. It's almost like magic, except that it's science. 

Use the red lenses when viewing anything but reds. Use the green lenses when you're viewing shades of red. Use the two together to black out everything -- just for fun; there's no practical use for both lenses simultaneously that we have found.

Includes:

  • 1/8" Acrylic Transparent Red Contrast Viewer
  • 1/8" Acrylic Transparent Green Contrast Viewer
  • 4" Ball Chain
