WebSep 6, 2024 · Light travels through the retina in a complicated process that begins when light enters the eye through the pupil. The pupil is the small opening in the center of the iris, which is the colored part of the eye. The iris controls how much light enters the eye by getting smaller or larger. Once light passes through the pupil, it hits the lens. WebDec 7, 2014 · Theoretically, the photon (or the beam of photons, there really isn't a difference) can go an infinite distance, traveling all the while at a speed c. Since photons contain energy, E = h ν, then energy conservation requires the photon to only be destroyed via interaction (e.g., absorption in an atom).
