What is the function of a rod in the eye?

Answer 1

The rods are cells in the retina of the eye which perceive colour. They together with the cones(which perceive brightness) contribute to creating an image in the retina and that's how we are able to see.

Answer 2

Rods are one of two types (the other are cones) of photoreceptor cells in the retina. Both are located at the back of the eye and gather strong and weak light. Rods are active at night and so are more sensitive in low light levels. Cones give sharp detailed central vision during daylight hours.

This effect can be noticed at dusk or dawn: when light changes from high to low levels, the rods are not fully active for night mode and so there is difficulty with vision when driving or riding a bike. For low to high level light change, cones are not fully active for daylight mode and again causes difficulty with vision when doing activities.

Answer 3

Rods allow you too see black and white, which is why they are used when seeing in the dark. Cones are used to see color.

Answer 4

The rods in human eyes are sensitive (photoreceptive) to light and dark, as opposed to the cones which are sensitive to colour.

Answer 5

Rods are cells on your retina. They are used for seeing in the dark and for seeing things at the edge of your vision.
