The Diffraction of the Spectacle

The diffraction of a spectacle refers to how light waves bend and spread out as they pass around the edges of a lens or an object. When light encounters a narrow opening or sharp edge, it doesn't just go straight through; it disperses slightly, creating a pattern of light and dark areas called diffraction. In spectacles, this phenomenon is negligible but can affect the clarity of vision if the lenses or edges are very small or sharply defined. Essentially, diffraction influences how sharp images appear and is a fundamental aspect of how light behaves when interacting with objects or openings.
