WebThere are about six to seven million cones in a human eye (vs ~92 million rods), with the highest concentration being towards the macula. [1] Cones are less sensitive to light than the rod cells in the retina (which support vision at low light levels), but allow the perception of … WebThe cone cells (for colour) and the rod cells (for low-light contrasts) in the retina detect and convert light into neural signals which are transmitted to the brain via the optic nerve to produce vision. Such eyes are typically spheroid, filled with the transparent gel-like vitreous humour, possess a focusing lens, and often an iris. WebRods are more sensitive to light than cones so they are useful for seeing in dim light. There … balista menu
