Do Rods Have Low Acuity

Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity.

Do rods have better acuity than cones?

While the visual acuity or visual resolution is much better with the cones, the rods are better motion sensors. Since the rods predominate in the peripheral vision, that peripheral vision is more light sensitive, enabling you to see dimmer objects in your peripheral vision.

Why are rod cells more sensitive to light?

One reason rods are more sensitive is that early events in the transduction cascade have greater gain and close channels more rapidly, as alluded to previously.
