A permanent anti-fog coating for eyeglasses may be available in the future.  Those who excercise, live in cool climates, and wear eyeglasses encounter foggy lenses from time to time.  This happens when moisture builds up on the cooler surface of your lenses.  Once the lenses warm up to the surrounding temperature the mositure re-evaporates and your lenses are again clear.  Anti-fog coatings have been around for a while, but they all fade over time and wash off with water.

Researchers at Laval University in Quebec City have developed a coating that can be applied to lenses that allows moisture to spread more evenly across the surface of a lens eliminating fog.  The coating is clear and and permanent even after washing.
