Web5 Jun 2007 · The period of integration is up to 0.1 seconds or 100 ms (for rods) and 10 to 15 ms for cones. The advantage of long integration time is that under limited light level conditions, threshold will be reached, whereas when light levels are not limiting (cone or photopic vision), a short integration time is preferable to improve temporal resolution. WebWhat is the difference in function between the rod cells and cone cells? Rods are ultra-sensitive to light and simply detect light, good for night vision. No color vision. Cones are responsible for color vision. What are the three types of cones? Cones come in 3 types: red, green, and blue.
