Frequently Asked Questions

Are rods more sensitive to light than cones?

The cones are less sensitive to light than the rods, as shown a typical day-night comparison. The daylight vision (cone vision) adapts much more rapidly to changing light levels, adjusting to a change like coming indoors out of sunlight in a few seconds.

What is the main function of rods and cones?

What is the main function of rods and cones? Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity.

Do rods or cones help you see in the dark?

There are more rods than cones in your eye – typically hundreds of millions – and these cells are responsible for helping you see in dark conditions, a state known as scotopic vision. Not only do your eyes have a greater number of rods, but these cells are also more sensitive than cones.
