Rod, one of two types of photoreceptive cells in the retina of the eye in vertebrate animals. Rod cells function as specialized neurons that convert visual stimuli in the form of photons (particles of light) into chemical and electrical stimuli that can be processed by the central nervous system.
Q. Are rods sensitive to light?
There are 2 types of photoreceptors in the retina: rods and cones. The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision. However, cones are most sensitive to one of three different colors (green, red or blue).

Q. What color do S cones see?
The human eye has over 100 million rod cells. Cones require a lot more light and they are used to see color. We have three types of cones: blue, green, and red.
Q. Where are rods located in the eye?
retina
Q. What would happen if we didn’t have cones?
In low light conditions, most of our visual perception comes from the rods. If one eye had no cones, there would be no color vision in that eye, and sharp detailed vision would be compromised. In that case, overall vision might not suffer too much, as the other eye would provide the missing information to the brain.
Q. What happens when rods and cones are damaged?
Deterioration of Rods and Cones Deterioration of cones and rods can cause decreased sharpness in vision, increased sensitivity to light, impaired color vision, blind spots in the center of the visual field, and partial loss of peripheral vision.
Q. What will happen if the rods and cones are missing from your retina?
The cones cells enables us to see the colours and makes us distinguish between various colours. So if Rods and cones are not present in retina , then person cannot see the objects at nights and during day time the person cannot see the colours at day time. Person may suffer with blindness.
Q. How would your vision change if rods were selectively damaged?
When the rod cells become more involved, affected individuals experience a decreased ability to see at night or in low light situations and may lose the ability to see clearly to the sides (peripheral vision).
Q. Which is more important rods or 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.
Q. Would you be able to see things in color if you didn’t have cones?
Still, people see the colors of some objects in dim light because their brains have memories of those same objects in bright light. This proves that the colors people see aren’t only determined by wavelengths of light or our cells. People who have colorblindness are missing some cone cells.
