What is the retina?
Its the part in the back of the eyeball that forms the image with the help of photosensitive cells
What is the fovea centrolis?
Its the dip in the back if the eye that is most dense with photosensitive cells
What are the two types of photosensitive cells?
There are rods and cones. The rods are responsible for producing clear crisp images. The cones are used for creating coloured images.
What is the optic nerve?
Its connected to the back of retina that carries the sensory information to the brain we can creat a image
