Optical Art is a mathematically-themed form of Abstract art, which
uses repetition of simple shapes and colors to create vibrating
effects, an exaggerated sense of depth, and other visual
effects.
Victor Vasarely
Bridget Riley
In the 1960's, the term "Op Art" was coined to describe the work of a growing group of
abstract painters. This movement was led by Victor Vasarely and Bridget Riley.

Op Art and The Science of
Perception (the way we see things)
The Op Artists studied the
science behind how the eye
and brain work together to
perceive color, light, depth,
perspective, size, shape,
and motion.
Op Art demonstrates the
relationship between the eye’s
(the organ that ‘sees’
patterns) and the brain (the
organ that interprets patterns).
Certain visual effects can
cause confusion between
these two organs, resulting in
the perception optical illusions.

MOTION
Optical Illusion and ‘Movement’
How can you create an illusion of movement on
a static (non-moving) 2D surface?
Studying the science of the eye gave Op Artists the
answer.
The use of repetition of pattern and
line, often in high contrast black and
white was one way Op Artists used to
create this illusion of movement. The
overall optical effect of the technique
leads the viewer to see flashing and
vibration.
Riley’s Untitled Diagonal Curve (shown right) is a good
example of this technique, where black and white wavy
lines are placed close to one another on the canvas
making the surface appear to shimmer and move
before the eyes.
DEPTH
Linear Perspective
The way of drawing that shows depth on a
flat (2-D) surface.
Because it is based on geometry Op Art is,
non-representational meaning the subject
is not a representation of an object.
However, despite this non-representational
nature, the Op Artists made use of the
traditional perspective techniques originally
developed to create the feeling of depth
and space..
Victor Vasarely’s Galaxie is a good example of the use
of perspective in Op Art with the centralized vanishing
point creating the illusion of a receding.
COLOR
Color Theory and the Science of Color
Colors appear to change depending on their
closeness to other colors. For example, a
red shape on a white background appears
much lighter than the same red shape on a
black background.
Complementary Colors: (Colors opposite
each other on the color wheel) when placed
next to each other seem to be of different
intensity than when placed far apart.
Cool Colors– blues, purples & greens – are
recessive and seem to sink back on the
surface
Warm Colors – red, orange and yellow are
emergent and pop out

All the lines are straight

"Rollers"
Rollers appear to rotate without effort. On the other hand, they appear to rotate in the
opposite direction when observers see this image keeping blinking.

Orthogonal Lines:
the line you draw from the corner of an object to the vanishing point
Where do all the orthogonal lines meet?
The Emphasis is on the area where all orthogonal lines meet.
