Transcript of 3D and Eye Science Project

The Human Eye! O_o Parts of the Eye Lens It is located right behind the iris.
It focuses on light rays.
Cornea primary focusing element of the eye
main job is to protect the eye
has two layers
Pupil dark circle at the center of the iris through which light travels through
Sclera the white tough of the eye wall Optic Nerve at the back of the eye
transports the information from the retina to the brain Iris inside the anterior chamber
dictates the eye color of a person
dialtes and contricts to let more or less light in Retina is a membrane lining the back wall of the eye
the cells within the membrane react to the presence and intesity of light
sends and impulse to the brain trhough the optic nerve

Virteous Humor a jelly like substance that fills the inside of the eye
normally clear Optical Illusions! How It Works Once a receptor is active it inhibits adjacent receptors. This inihibition createscontrast hilighting edges. In this illusion, the gray spots appear at the intersection because of the inihibitory which occurs as a result of the increased dark surround. 3D Movies Old 3D movies use anaglyph images to take
advantage of binocluar vision and parallax.
These images include two color layers in a single
strip of flim shown from one projector. One layer
is red, while the other is blue. To watch a movie,
you must wear glasses with one blue lens and one red lens.
These lenses force one eye to see the red part and the other
eye to see the blue part. Because there is a difference
between the two, your brain sees it as one 3D image.
