Anti-reflective coating is a special layer applied to lenses, such as those found in glasses or camera equipment, to reduce glare and reflections. This coating allows more light to pass through the lens, improving visibility and clarity. It is particularly beneficial in bright environments or when using digital screens, as it minimizes distractions caused by reflections. The coating works by using multiple thin layers of material that interfere with light waves. When light hits the lens, some of it reflects off the surface, but the anti-reflective coating helps to cancel out these reflections. This results in clearer vision and a more comfortable viewing experience for the wearer of glasses or the user of cameras.
