Retinas
The retina contains the rods and cones. There are more rods than cones but is is more like 120 million rods to 5 million cones. Both are special cells that are photoreceptors. This means that they are sensitive to light. The cones are best for color vision but the rods are for low light. That is one reason why you don't see color in low light.
There are about 120 million rod cells compaired to 6 million cone cells, for a ratio of about 20 rods for each cone.
Rods are responsible for night vision and detecting low light levels, while cones are responsible for color vision and high acuity vision. Rods are more sensitive to light than cones but do not perceive color. Cones are concentrated in the central part of the retina, while rods are more abundant in the periphery.
The average human has about 90-120 million rod cells and 6-7 million cone cells in each eye.
The retina contains two types of photoreceptor's, rods and cones. The rods are more numerous, some 120 million, and are more sensitive than the cones. However, they are not sensitive to colour.
The human eye has two types of light receptors: rods and cones. Rods are responsible for vision in low light conditions, while cones are responsible for color vision and detail in brighter light. There are about 120 million rods and 6-7 million cones in the human eye.
Rods and cones are photoreceptors in the eye that allow people to see. Rods allow people to see colors, while cones allow people to see in low light, and in great detail.
The retina is located at the back of the eye. It is a thin layer of tissue that contains cells sensitive to light and helps process visual information before sending it to the brain through the optic nerve.
The three types of cones found in the retinas are red cones, green cones, and blue cones. These cones are responsible for color vision and work together to detect different wavelengths of light, allowing us to perceive a wide range of colors.
It is 120 million in the Philippines and everywhere else.
The longest curtain rods out there are 120", however custom curtain rods can be made longer if neccessary.
380 million.
