Want this question answered?
The cones are the sensory receptors responsible for picking up light of different wavelengths and therefore colours. These are concentrated in an area of the retina called the macular lutea in particular in a pit called the fovea.
The highest concentration of cones in the retina is 50 per 100 micrometers in the central fovea. (from wikipedia) So there are approximately 17,500 cones in central fovea.
retina
-Peripheral areas of the retina contain very few, if any, retinal cones. Those areas contain only rods, which cannot distinguish color. -Cones are necessary to see color, there are 3 types of cones (red, green, and blue), mostly concentrated in the center of the macula, which is known as the fovea.
The highest concentration of cones is in the macula. The fovea centralis, at the center of the macula, contains only cones and no rods. The macula is a small, yellowish central portion of the retina. It is about 5.5 mm in diamter and is the area providing the clearest vision.
Rods and cones are inside a layer of the eyeball called the retina.
cones help us to see color
the cones which sence colour are concentrated near the center of the retina. when looking straight at an object it maxmizes the number of cones being stimulated. Alice rocks!!!!!!!!!!!!!!!!!!!!
The retina (the red of your eye that you sometimes see in photographs) are where the rods and cones are located.
There are two types called rods, which a simply sensitive to light and dark, and cones which are sensitive to colours. Both types are found on the retina but the rods dipsersed evenly over the surface whereas cones are concentrated on an area called the fovea.
Rods and cones are in the sensory components in the retina of the eye. They are essential to the sense of sight.
The retina of the eye has rods and cones.
