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 - SandraStark 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.)
One of the possible causes of symptoms of
dyslexia, migraines, and/or epilepsy is the Red Focused Vision (RFV) and near vision stress caused by having a higher ratio of Red to
Green photoreceptors
(75% red and 20% green photoreceptors).
That Red
Focused Vision 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. Green Focused Vision (GFV) - with 50% red and 45%
green
photoreceptors enables a more stable close visual image. Photoreceptor Distribution
Red Focused Vision (RFV), 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 Green Focused Vision (GFV). If you can detect only the spinning Blue Dyop® ring you have Red
Focused Vision (RFV). The higher-red ratio
(75% red and 20% green) of Red Focused Vision (RFV)
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 Red Focused Vision 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.
Red-Focused Vision contributes to an
unstable near-image. That unstable near-image
is symptomatic of dyslexia, and likely a catalyst for migraines and epilepsy.

Dyops® create a unique, and
previously unavailable, ability to understand and experiment with visual
perception. The Dyop® color/contrast test uses the Red Focused Vision (RFV) versus Green Focused Vision (GFV) 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. - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
