Put your 3D glasses on now…
The red goes on your left eye.
Red Cyan 3D Glasses• Overlapping two slightly
different images of opposite colors can produce a 3D image. Your brain will combine the images, creating a 3D effect.– The red filter only allows red
light through– The cyan filter allows blue and
green light through

Color Vision
Color Vision Deficiency / (Color Blindness)
• About 0.4% of women and 8% of men are affected by some type of color blindness
• The most common type of color blindness is a form of red-green color blindness called deuteranomaly. This means that the green cones of the eye are sensitive to “incorrect” wavelengths, affecting perception of the colors green and red.
• People can also have absent or non functioning green cones, causing a more severe form of red-green color blindness.
• Less commonly, people can be blue-yellow color blind.• Very rarely, people can have monochromacy, and only see in
black, white, and gray.

Polarization• Light travels as a transverse wave, with the electric
and magnetic fields oscillating perpendicular to the forward motion of the wave
• Light from the sun, from a lamp, or from a candle is all unpolarized– Unpolarized light oscillates in many planes– Polarized light only oscillates in one plane
Polarization• Polarization occurs when you take unpoloraized light
and make it polarized• Using a polarizing filter (or Polaroid) absorbs some of
the incoming light, reducing the amount or intensity of light passing through the filter
