Visual Optics

Visual optics is the branch of optics that focuses on how the eye perceives light to form images. It studies how light enters through the cornea, passes through the lens, and hits the retina, where it is converted into signals sent to the brain. This process involves refraction, which is the bending of light rays as they move through different mediums, ensuring that images are focused correctly. Visual optics also examines how lenses, like those in glasses or cameras, can correct vision by modifying light paths to improve clarity and focus.
