Nanocoatings are thin layers of materials, often only a few nanometers thick, applied to the surface of glasses to impart specific properties. These coatings can provide anti-reflective, anti-fog, and self-cleaning functionalities. For example, anti-reflective coatings reduce glare and improve vision clarity by minimizing light reflections. Similarly, anti-fog coatings prevent condensation on the lenses, ensuring clear vision in various environmental conditions.
