Veiling glare is a phenomenon that occurs when bright light scatters within a lens or optical system, reducing contrast and detail in an image. This scattering can happen due to imperfections in the lens or when light reflects off surfaces, creating a haze that obscures the subject being viewed. In photography and vision, veiling glare can lead to less sharp images and can be particularly problematic in high-contrast situations, such as when shooting towards the sun. Understanding and managing veiling glare is essential for improving image quality in devices like cameras and binoculars.
