Iris and Kori -eye pupil- (b)<\/o:p><\/font><\/font><\/span><\/u><\/span><\/p>\n

 <\/font><\/o:p><\/span><\/span><\/p>\n

The other one, Kori, the eye pupil (the only part to on human being who is actually black) traps deep inside its “cave” as much of light radiation is needed for the project of visual perception. <\/o:p><\/font><\/font><\/span><\/span><\/p>\n

There is no return for the light pass by the entrance of Kori’s chamber. That light cannot pass back out from the threshold to shine again in the outside world. <\/o:p><\/font><\/font><\/span><\/span><\/p>\n

Some of this light conflict in the rods and cones in the retina irritating it and helps for the light perception. <\/o:p><\/font><\/font><\/span><\/span><\/p>\n

It passes through the optic nerve and directed to the relevant part of the brain it is imprinted as image. The rest that didn’t manage to irritate some cones or rods, disappears on the the retina. A small Hades exists in each eye and in that cave of Hades’ queen a divine mystery is unfolded at any time. <\/font><\/span><\/span>
\nBut what is the retina on which happens the drama of light perception and representation? <\/span>
\nThis is a photosensitive substrate of the eye globe, on which there are about 120 to 140 million rods and only 6 to 7 million cones. Rods are responsible for the perception of brightness, while cones decode color radiation when they are irritated. Both have a pigment called rhodopsin which is irritated by the light rays and turn on the rods and cones in operation. <\/span><\/font><\/font><\/span>Rhodopsin consists of a protein and a retinol, a derivative of vitamin A. <\/font><\/span><\/span>
\nSo if you want to have good eyesight, eat foods rich in vitamin A. Eat a lot of carrots. <\/span>Like Bugs Bunny.<\/font><\/font><\/span><\/span><\/o:p><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
