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. - - - - - - - - - - - - - - - - - - - - - - -

may NOT seem to be a
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. - - - - - - - - - - - - - - - - - - - - - - -
