Eye Cells act as light pipes (fibre optics)

Researchers have worked out how the eye is able to guide light to the cells in the eye that are sensitive to light.  The retina is the part of the eye that is sensitive to light.  The retina is located at the back of the eye. Light sensitive cells are called photoreceptor cells. At first, scientists were not sure why the eye was “blurring” the light before making use of light for image formation.   The cells on top of the photoreceptors have the ability to guide light to photoreceptor cells.
