| | Eyes are very complex sensory organs that allow us to percept all the beauty of the world we live in, to read and gain knowledge, and to communicate to each other through visual expression and visual arts.
The eye is a principal optical device designed to focus the visual images on the retina. Journey of the light, which has a dual nature as wave and particle, starts with the cornea and lens. Next, it traverses the vitreous humour which fills the eye cavity before being absorbed by the photoreceptor cells that are in the shape of rods and cones.
The incoming light waves are converted to the electrical signals that stimulate neurons in the retina. Although this general visual mechanism seems to be well discovered and explained, neurobiologists still research on the details of the circuit that provides vision in human eyes.
In this seminar we follow the journey of light through the eye, and describe some physical points of view regarding the visual processing by the retina.
