Improvised snow goggles can greatly limit the amount of light entering the eye and help reduce the chance of snow blindness. They can be fashioned from duct tape, strips of cloth, a soft strip of leather, or even inner bark strips. Select a piece of material that is wide enough to cover your eyes (duct tape is just right) and long enough to wrap around your head and fasten. Cloth is easy to tie, so it can be knotted in place; leather can be fitted with a toggle or button; and the duct tape can stick to itself. For quick-and-dirty duct tape snow goggles, tear off a piece of tape a little over two feet long. Fold it almost in half and let the sticky sides adhere to each other. The offset gives you a sticky tab on one end of the tape to fasten the band to itself. Next, lay the strip on a smooth log or similar surface. With a sharp knife, cut slits 2 inches long and about 3/16 inch wide, spaced where your eyes would be. Wrap the strip around your head, stick the tape to itself and you’re done. These are also good for blocking the glare of the sun in deserts and on the open water.
