Transcript of Science Part 1: How We See

The Way We See The human eye can do amazing things! Presentation by
Carson Covell and
Christian Bueche How the Eyes Work Light rays bounce off objects to enter
your eyes. Once the rays enter the eye through the pupil
they go to the retina which holds tiny nerve sensing cells. Functions of the Different Parts of the Eyes Cornea - bends or refracts so that
they will enter the pupil Iris - Controls how much light
enters through the eye Retina - Holds the nerve sensing cells that tell the message to the brain of what light is being seen These cells can then detect the light rays that are coming in and send the message to your brain so that you see them as light. Pupil - The passageway through which
the light enters the eye Sclera - The tough muscle that surrounds
the eyeball and holds it in place Optic Nerve - Carries the elctrical message
recieved in the retina to the brain so that you
see the image Virteous Humor - Jelly like substance that fills
the eye from the lense back Lense - Bends image so that it can be seen
as a clear image Understanding the Human Eye Optical Illusions Parts of your eyes receive rays of light at different speeds.
This way you see different parts of the image at different times When this happens the image that the eyes are seeing is different than what the brain thinks should be seen resulting in an optical illusion 3D How it works There are Two Different Types of 3D Imaging Anaglyph Polarized Uses the Conlimentary colors that are on the screen (red and blue)
These colors corespond to the lense colors which are one red and one blue
When the colors cancle each other out it makes the image appear to be in three demensions Two images are projected superimposed onto the same screen
You wear glasses with two different polarized lenses that will only let in certain light
Since each lense will only let in light of the same polarization this creates two creates a three demensional image on the screen
This way of viewing 3D is higher quality and will be more enjoyable to watch The History of 3D 3D imaging was orgiginally used in comic books in the 1950s. At the time anaglyphs were used to make the pictures pop out at kids or anyone else that was using them. The technology used to produce these 3D comics was enventually transferred into movies that can be still seen today. These movies were originally made with red and green as the two main colors but were then changed the red and blue because it proved to be more effective.
