“Any sufficiently advanced technology is
indistinguishable from magic.”
Arthur C. Clarke’s Third Law
International Vision Standards
1988
“Visual resolution, as used in optics and visual science, refers
to the ability to just detect a break in a line or the separation of
parallel lines or points of light (minimum separable).
This class of thresholds can be measured using short bars,
Landolt rings, gratings or other targets.”

How Dyops™ Work
• The eye is a digital camera, NOT analog
• Dyop™ precision based upon physiology
• Dyops™ can be virtually any rotating shape

The Threshold Distance is the maximum distance where
The Threshold Image can still be perceived as rotating.
Arc degree perception threshold remains constant.

“Any sufficiently advanced technology is
indistinguishable from magic.”
Arthur C. Clarke’s Third Law
Animated Vision Associates
When a distinguished but elderly scientist states
that something is possible, he is almost certainly
right. When he states that something is
impossible, he is probably wrong.
Arthur C. Clarke’s First Law

“The benefit of technology is NOT in what it lets
people accomplish, but in how it improves the
character of people.”
