Introducing
the "Revolutionary" Dyop® Test
The 21st century vision test which takes the
Guesswork out of vision
An “optotype” is the technical term for a
visual target. A Dyop® (short for dynamic optotype) is a spinning
ring visual target with contrasting segments and gaps (typically Black/White)
which provides a strobic stimulus to the photoreceptors of the eye. That Dyop
strobic stimulus functions akin to a visual “tuning fork” and enables it to precisely
resonate with the inherent vibratory motion of the
photoreceptors caused by the visual saccades.
Those saccade vibrations enable the refresh of the photoreceptors which
facilitates vision being a dynamic and autonomic process, and enables the
chromatic triangulation of acuity as the colors red, green, and blue to
provide autonomic focus for the biological lens. That Resonance
Acuity provides for a more precise
acuity and refraction measurements than static optotypes. The constant stimulus from “traditional”
static optotypes tends to deplete the photoreceptor response and creates a
potential for an overminused refraction and the
possible increase in the incidence of myopia. “It Spins. You See
It.”
Vision is a dynamic process which facilitates us to eat
rather than be eaten. That dynamic process
is enabled by the inherent
photoreceptor vibratory motion of the visual saccades. That motion refreshes the response of the
photoreceptors in the back of the retina much as do the refresh lines on your
monitor. The response of the
photoreceptors has the neurons on the retina inner surface act as the
equivalent of a biological circuit board.
The constant saccade motion also enables the blue, green, and red
photoreceptors to provide chromatic triangulation of their focal depths
regulate acuity. The need for that dynamic process
results in vision tests using static visual targets tending to be
imprecise and inconsistent, and may actually be making people blinder. The smallest Dyop
angular width diameter where the direction of spin can be detected is the
visual acuity and refraction endpoint.
At a sub-acuity diameter, the direction
of Dyop spin cannot be detected.
The motion of the saccades results in the perception of the strobic Dyop
segment/gap motion Resonating with
the saccades refresh rate. A Dyop
functions much as a visual equivalent of an audio tuning and fork uses Resonance Acuity to match the saccade
refresh rate of the photoreceptors.
That Dyop strobic Resonance
Acuity results in Dyop vision testing being three times as precise, with
one-sixth the variance, and up to three times the efficiency of Snellen or
other letter-based vision testing.
Unlike
letters, which are culturally dependent on Recognition Acuity, the Dyop Resonance
Acuity is based on the physiological refresh response of the
photoreceptors of the eye. As a Dyop
ring gets smaller, or you move further away from your computer screen, you
should no longer be able to detect a smaller Dyop ring as it is
spinning.
Resonance Acuity and the photoreceptor refresh response are essential for survival and
give your eyes a preference for detecting motion. As you fixate on the Plus (+) in the circle
image below you will likely see a moving Green circle which appears as the
Pink circles seem to rotate around that Plus.
The moving Green circle appears because of the strobic
photoreceptor refresh rate, the depletion of the Red photoreceptors, and
their (depleted) inability to respond to the color Red in the Gray
background.
Dyop visual testing has greater precision and less variance than
static visual targets

Your eyes function similar to the pixels receptors
in a computerized video camera. As you read these words you have
the illusion that you are seeing lines and shapes and letters. What you are actually seeing are pixels of
light generated by electronic phosphors within the surface of your computer
screen. However, those electronic
pixels are perceived by the photoreceptors of the retina in the back of your
eye. Those photoreceptors in your
retina respond to light as biological pixels.
Those biological photoreceptor pixels combine their response
(primarily to the colors blue, green, and red) into giving you the perception
of vision. Color Screening and Dyslexia Screening The eye’s
photoreceptors not only allow you to see in color, but the refresh rate
of the photoreceptors combines with the strobic saccade process to create a
matrix response to color-perception which allows the photoreceptors to track
changes in the location of those images.
The saccade process functions much as does the scanning lines of the
pixels on your computer monitor to keep the image from burning into the
screen. The response of about 100
photoreceptors combines to create the stimulus for each optic nerve fiber
going to the brain which creates vision and brings that image into
focus. However, the neural ganglia
layer of the retina “process” those photoreceptor responses in clusters of
about 20 photoreceptors much as a biological circuit board with the emphasis
on patterns of motion and proximity so that it takes the adjacent stimulus of
five clusters of 20 photoreceptors for an optic nerve fiber to respond. The comparative focal depth of the colors blue, green, and red of the images also regulates the
shape of the biological lens and adjusts focal clarity.
See www.redgreenscreening.com for the genetic color screening test. The History of Vision Measurement Thousands
of years ago, visual clarity (acuity) used Resolution Acuity as defined by the ability to see the nighttime
gap between two of the smaller stars in the handle of the Big Dipper
constellation.
In
1862 Dutch Ophthalmologist Herman Snellen
used the Recognition Acuity
ability to identify (European) letters as a benchmark for visual acuity. By then, reading had become a dominant
economic and social skill in Europe.
Snellen used the convenience and cultural bias of black letters on a
white background as his benchmark, although most of what we see is NOT in black and white, and other
cultures use pictographs rather than letter-based words. The Dyop Resonance Acuity is three times as precise, with one-sixth the
variance, and up to three times the efficiency of Snellen and other letter-based
vision testing. |

The personal use of the Dyop test
is intended to only measure visual clarity.
A PRESCRIPTION for glasses or
contact lenses requires vision testing and a refraction performed by an eye doctor
because it CANNOT be done on a two-dimensional display such as a
computer. You can measure your vision with
the Dyop test using the Dyop Personal Acuity Test. If you can’t see clearly enough, GO SEE YOUR EYE DOCTOR. Dyop®
tests are for vision screening
purposes only and
are NOT a substitute for an examination by a
licensed vision care professional. “Any sufficiently advanced technology is indistinguishable from
magic.” As a culture we are
only as good as our memory. As a
species we are only as good as our vision. Just as the hand, held before the
eye, can hide the tallest mountain, so the routine of everyday life can
keep us from seeing the vast radiance and the secret wonders that fill the
earth. -
