    Can you believe your eyes? Not always. Here you will discover that eyes are just the beginning of our complex visual system. That system includes the brain which can be fooled into seeing things that aren’t there. Learn how by exploring some eye opening optical illusions.

    Increase Your Eye Q

    Vision is a complex sense. The eyes are the entry to a multilayered visual system that processes millions of bits of information every second. In fact, seventy percent of the body’s sense receptors are found in the eyes. Let’s take a closer look.

    • Can You Name The Parts Of The Eye?

    Binocular Vision

    Humans see the world with two eyes. This is called binocular vision. However, since our eyes are about two inches apart, each eye sees a slightly different view. Our brain combines the views together forming a 3-D picture.

    Key Concepts:

    • What Is Depth?
    • What Is A Blind Spot?

    Experiments:

    • Different Views
    • The Hole In Your Hand
    • Find Your Blind Spot

    The Eye-Brain Connection

    Seeing happens in your brain. Your eyes take in information from the world around you in the form of light. That information is sent to the brain, which makes sense of what your eyes are seeing.

    Key Concepts:

    • What Are Optical Illusions?

    Activity:

    • Optical Illusion #1: Train Tracks
    • Optical Illusion #2: Rotating Staircase
    • Optical Illusion #3: Barrel
    • Optical Illusion #4: Smiling Frogs
    • Optical Illusion #5: Two Straws
    • Optical Illusion #6: Two Flowers

    Persistence of Vision

    Persistence of vision is the ability to keep seeing an image for a fraction of a second after it has disappeared from view. Your retina and brain retain a visual impression for about 1/30th of a second. This principle is what makes movies and cartoons work.

    Key Concepts:

    • Moving Pictures

    Activities:

    • Make A Spinning Disc (Thaumatrope)
    • Make A Flipbook
