Dyslexia Screening

 

 

 

Not everyone sees color in the same way.

Color perception affects your visual skills and personality.

 

 

Dyop® Color Screening may be indicative of symptoms of dyslexia, migraines, and epilepsy.

 

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). 

 

One of the possible causes of symptoms of dyslexia, migraines, and/or epilepsy is the near vision stress in having a higher ratio of Red to Green photoreceptors (75% red and 20% green photoreceptors).  We call that 75%red/20%green photoreceptor ratio Image Based Vision or “Red-Focused Vision” – (RFV).  That Red-Focused Vision increases the visual stability of distance images but also increases the instability of the lens when it needs to focus on near images.   That RFV visual dissonance at near distances is associated with associated with dyslexia-type symptoms.  Letter-based or Green-Focused Vision – GFV (50% red and 45% green photoreceptors) enables a more stable close visual image.

 

Image Based implies that you see words as pictographs rather than as letter-based combinations.

Dyops® create a unique, and previously unavailable, ability to understand and experiment with visual perception.  We have created a series of experimental Dyop® color/contrast tests whose Red-Focused response by subjects seems to significantly correlate to symptoms of dyslexia, migraines and epilepsy.

There are approximately 100 photoreceptors for every optic nerve fiber.  The retina neural ganglia layers “process” those photoreceptor responses 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.

 

The Dyop® (Dynamic Optotype™) tests and concept are covered under U.S. Patent US 8,083,353

and International Published Patent WO 2011/022428.
