Smartphone displays, computer monitors, TV screens – artificial sources of blue light are ever-present, both in our everyday working lives and in our private lives.

Safety spectacle lenses are usually coated to prevent fogging and/or scratching. An anti-fog coating is especially important for high humidity environments or physically demanding work, such as in the paper or food industries. For work involving high dust exposure, for example on construction sites, an effective scratch-resistant coating is necessary so that dirty lenses do not become scratched when they are cleaned. This improves the comfort of the person wearing the safety spectacles, allowing them to concentrate to the best of their ability on the most important thing – their work.
