The Rod-Cone-Break is considered to be a d</span>ark environment adaptation function in the eye, wherein for an estimated time of the first ten minutes in the dark, the cones<span> needs less light to reach a threshold response than do the </span>rods<span>. Thereafter, the </span>rods<span> need less light. The point at which the </span>rods<span> become more sensitive is called the </span>rod-cone break<span>.</span>
