Photoreceptors are the fundamental component of the entire vision process. These specialized cells that absorb light and trigger a specific physiological reaction in the body come in two varieties: cones (responsible for sharp color vision) and rods (responsible for black-and-white vision in low light, e.g. after dark). To properly receive visual stimuli and perceive the world around us, we need both in large quantities.
New method allows quick measurement of photoreceptor response
