A new gold standard for antifog eyewear

Swiss researchers have developed a transparent gold nanocoating that vanquishes the perennial nemesis of glasses wearers – fogging.

Unlike traditional antifogging methods, which uses hydrophilic coatings that evenly spread condensation across the surface of the glass, the micro-thin gold layer developed by scientists at ETH Zurich harnesses sunlight to passively heat the lenses to prevent fog from...
