Not everyone sees COLOR the same way.
The Dyop® test enables measuring acuity in COLOR as well as in Black and White.
Color perception affects your visual skills and personality.

Dyslexia
has little to do with intelligence, or limited
intelligence. Instead, it seems to be a caused by visual stress
which reduces the ability to read letter-based words. There
likely is a correlation between color perception and symptoms of dyslexia,
migraines, and epilepsy. Dyop® Color
Screening may be a useful indicator of potential symptoms of
dyslexia, migraines, and epilepsy. Color Perception and Dyslexia
– Sandra Stark Dyop Color
Perception as a Potential Diagnostic – Isiaka Sanni Other
Research Articles: Harris – Colored Contacts Paper Harris – Colored Contacts Poster Correlation of Reading Speed to L/M Ratios Visual acuity (and accommodation) is
regulated by the comparative responses by the cone-shaped Red
(L), Green
(M), and Blue
(S) cone photoreceptors in your eyes. The
cone photoreceptors function as pixelized biological receptors of color much
like those of a digital video camera. The cone photoreceptors also
use the focal length disparity between Red and Green to
adjust the shape of the lens and bring the overall image into focus
(accommodation).
There are approximately 100 photoreceptors
for every optic nerve fiber. The retina neural ganglia layers
“process” those photoreceptor responses in clusters of about 20
photoreceptors as a biological circuit board with the emphasis on patterns of
motion and proximity. Static photoreceptor stimulation tends to be
ignored or increase visual strain. The difference in the
perception of color allows the eye to use those colors to create chromatic
triangulation to regulate the focal length of the lens, with Blue, Green,
and Red at
increasing focal depths. Acuity
endpoints vary as to specific colors and visual perception group. Smaller
arc width or Snellen ratio indicates better acuity. The above color/contrast permutations are
included in the Dyop professional test as part of the Chart2020 vision test
platform. Dyslexia
also seems to be associated with HOW we see colors. Your Red/Green ratio
determines HOW you see and WHAT you see. Ask
your friends what THEY see as to The Dress
(below).
One of the possible causes of symptoms
of dyslexia, migraines, and/or epilepsy is the Near Vision Stress (NVS) caused by having a higher ratio of Red to Green photoreceptors
(75% red and 20% green photoreceptors). Near Vision
Stress (NVS) increases the visual stability of distance images
but also decreases the stability of the lens when it needs
to focus on near images. That visual dissonance
at near distances is associated with dyslexia-type symptoms. A Stable Near Image
(SNI) - with 50% red and 45% green photoreceptors, enables a more
stable close visual image. Photoreceptor
Distribution
Near
Vision Stress (NVS) enables a more
stable distance image which facilitates spotting predators
and game and seeing pictographs as words, rather than words as letter-based combinations, and may contribute to symptoms of
dyslexia, migraines, and epilepsy. Dyop color/contrast screening test To
screen for the color vision group, select the FREE Dyop®
Color Screening Test above for use on a PC, iPad, or SmartPhone (iPhone or Android). Move
away from the identical-diameter spinning Dyop® rings until you CAN
ONLY detect either the
spinning Green-on-White Dyop® OR the Blue-on-Black
Dyop®. You can also use
the Minus (-) or Plus (+) symbols to make the spinning rings
smaller or larger. For a proper color perception screening,
the test should be taken without wearing your glasses or
other corrective lenses. If you can detect only the spinning Green Dyop® when the spinning rings get
sufficiently smaller or further away, you
have Stable Near Image (SNI). If
you can detect only the spinning Blue Dyop®
ring you have Near Vision Stress (NVS). The higher-red
ratio (75% red and 20%
green) of Near
Vision Stress (NVS) contributes to an
unstable near vision but enables you to better see pictographic words
rather than letter-based word combinations.) The
spinning Dyop® color images below are
for use on a Smart Phone or tablet.
When you
move away from the screen, detecting spinning of ONLY the Blue-on-Black
Dyop® is potentially indicative of Near Vision Stress
(NVS) and
symptoms of dyslexia, migraines, or epilepsy. You
may also use the colored spinning GIF files on this webpage
(above) by moving away from the spinning images and noting, when they are
sufficiently smaller, as to whether you CAN ONLY detect spinning of the Green-on-White Dyop® OR the Blue-on-Black
Dyop®. The
following is a Static image screenshot of the Dyop® Color/Contrast Screening Test. Near
Vision Stress (NVS) contributes to an
unstable near-image. That
unstable near-image is symptomatic of dyslexia, and likely a catalyst for
migraines and epilepsy. -

factor with Dyscalculia (number dyslexia). |

A Dyop® creates
a unique, and previously unavailable, ability to understand and experiment
with visual perception. The Dyop® color/contrast test uses
the Near
Vision Stress (NVS) versus Stable
Near Image (SNI) response to significantly correlate to
symptoms of dyslexia, migraines and epilepsy. Previous
Color/Contrast Research Using
the ability of a Dyop test to determine precise acuity endpoints, a matrix of
color/contrast permutations was created to validate those specific color
acuity endpoints. Dyop Color Matrix with 60 color/contrast permutations Dyop Color Matrix with 60 color acuity endpoints - visual
threshold endpoint distances in feet. It
was subsequently realized that the color/contrast acuity endpoint for some
individuals with dyslexia significantly differed from individuals WITHOUT
associated symptoms of dyslexia, migraines, or epilepsy. 31
permutations of the Dyop Color Matrix for dyslexia screening The 31 color/contrast permutations became
the basis for a Dyop duo test which can be used as a ten second color vision
group screening test for potential symptoms of dyslexia, migraines, and
epilepsy. -
