EYE: v7

SEE THROUGH NERVES: After light passes through your pupil and then though your constantly moving lens, it immediately enters the vitreous humor liquid. 

SEE THROUGH NERVES: After you go through the lens and then through the vitreous humor, you bump into something. What? 

SEE THROUGH NERVES: At the back of your eye in your retina, light first hits the noodly nerves on top of the retina. It then goes through them and hits the the ganglion cells,.  After light goes through the ganglion cells of the retina, it hits the bipolar cells which are right under them.

SEE THROUGH NERVES: Finally after going through the ganglion cells and the bipolar cells of the retina, light next hits the third nerve cell layer, the rods and the cones. 

SEE THROUGH NERVES: In the rods and cones, light strikes different kinds of opsin protein molecules. These proteins cause the rod and cone cells to send signals to the brain to enable you to see waterwheels, wagons, wolverines, and weasels…whatever!

SEE THROUGH NERVES:  Scientists recently discovered that there are special pink cells that live in your retina that tunnel through the maze of nerve layers in the retina including the ganglion and bipolar cells. 

SEE THROUGH NERVES: You have millions of these living, clear tube cells which act like spaghetti noodles.  They channel the light through the nerve maze directly to your rods and cones. It makes it so the world doesn’t look fuzzy and dark to you! 

FOVEAS: The fovea is a tiny, 1.5 inch dent in the back of your eye where over one million color-detecting cones are located.  That’s an area the size of a little pebble!

FOVEAS:   When you look at anything like a rabbit on a hill, both your eyes’ tiny fovea must be perfectly aimed at it or you’ll have triple vision….all the time.  Not so fun!

FOVEAS: Though our fovea are tiny, they are the only part of our eye that we can see 20-20 with.  They are the part of our eyes that we focus with. Half the messages going to our brains from our retina are from the fovea.  Fovea are hugely important!
