. 'Iris' is a muscular diaphragm lying between the aqueous humor and the crystalline lens. Iris has an adjustable opening in the middle called the pupil of the eye. The pupil appears black because all the light entering is absorbed by the 'retina', which covers the inside of the rear part..

Atmospheric refraction is the shift in apparent direction of a celestial object caused by the refraction of light rays as they pass through Earths atmosphere. The twinkling of stars and variation in size of the Sun are due to atmospheric refraction of starlight. Twin..

They are the visual sensory organs. They are equipped with the photoreceptors called the rods and cones. In humans, there is a pair of eyes that are directed forward and give binocular vision. The eyes are situated in the eye sockets or orbits of the skull. Human ..
