There are two types of photoreceptors in the retina, cone cells and rod cells. There are 92 million rod cells in a retina. Rod cells function in less intense light and are important for peripheral vision and night vision.

How is it useful when cats eyes flash in the dark?
It's the reflection of the light off of the rods in the back of the eye. Humans have the same rods, they just do not have as many, which doesn't allow for the reflection. And due to the reflection of the light, the cat is able to see in the dark.
Which animal's eye is bigger a whale or a horse?
horse
Which animal has largest eyes?
The giant squid has the largest eye. It is approximately the size of a basketball.
Why do lions have better eye sight at night time then humans?
Lions have an eyesight that is very similar to a cats. The retina is much more sensitve in a lions eye so it detect light better. They also have something called 'rods' in their eye which are very sensitive to small amounts of light and allow animals to see in poor light conditions. But this normally means they cannot detect colour. There is a higher proportion of rods in animals with good night vision (noctunal animals).
What animal can lose an eye and grow a new one?
Dog fish
Do rods detect color in eye receptors?
Rods are used to detect variances in light and are perceived as black, grey and white. Cones are used to pick up colors.
What do rods do for the eye?
Rods are the primary pigments in the retina of eye detecting black and white light or objects.
Where do you find rods and cones in your eye?
in yor eye
How your eye works?
Your eye has cones and rods that are stimulated by light.
How many rods are in the human eye?
*
What are rods and cones for a cows eye?
Rods are a part of the eye that takes in low light. Cones are located in the retina and they are responsible for seeing in color. All mammals have rods and cones in their eyes.
Where do you find rods and cones?
You find rods and cones in the back of your eye near the retium
What are rods in the eye sensitive to?
The rods (themselves) are sensitive to light The cones are sensitive to colour
In the eye rods and cones are found?
Rods and cones are found in the retina at the back of the eye. They are directly connected to nerve cells that lead into the brain.
Where are the rods and the cones of the eye found?
The retina
What parts of the eye are used to see colour?
The retina is mostly rods and cones. They are placed across the back of the eyeball. The cones are the color receptors. The rods give the light intensity information.
What is the major function of rods in the eye?
The major function of Rods in the eye is that of Photo (light) reception. They are more sensitive to light thn are the cones, but are not color sensitive,The rods are photo receptor cells found in the retina. Their main function is to help the eye see in dim light.
