The brain takes in and interprets information (words) at the moment when the reader’s eyes fixate on a word rather than during a saccadic movement. Uncontrolled, high amplitude/high frequency involuntary eye movements, or ‘overactive saccades’, appear to be a causal factor in word and line skipping. The understanding of the meaning of text initially relies on the brain's pattern recognition process. If a reader's eyes are erratically jumping from place to place on the page due to overactive saccades, three things can negatively impact cognitive processing: 1. the eyes may fixate on the wrong word(s), 2. the pattern of words is disrupted, and 3. the peripheral vision is unable to effectively predict upcoming text. In effect, the text becomes meaningless, thus reducing or eliminating both fluency and comprehension.


There are four issues that can impact the visual process when reading: 

1. Pattern Glare. Refers to the illusions of color, shape and/or motion that a person may experience as part of their visual perception (readers say that “words appear to move on the page”). These symptoms can impact the ability to cope with black lines on white backgrounds (e.g., text on white paper). Sufferers have a range of symptoms including losing their place, headache, eyestrain and eye fatigue. Sufferers can be extremely sensitive and can experience great discomfort, thus reducing willingness to read.

2. Eye Dominance. Unstable eye dominance may cause loss of place (e.g., word- and line-skipping). Cross dominance may be a factor in mixing up letters (saw vs was) and letter reversals (e.g., dyslexia).

3. Visual Field and Peripheral Awareness. The peripheral vision surrounding the point of the eye’s fixation impacts how the reader integrates upcoming information with his/her central vision. In skilled readers, approximately 90% of saccades move the eye forward, with the remaining 10% moving the eye backward in the text (regression) either to resolve comprehension difficulty or resolve errors (Gaskell, M. and Altman, G., 2007, p. 327). The implication is that less skilled readers may spend an even greater percentage of time on regression, slowing them down and/or disrupting pattern recognition; i.e., reducing fluency and comprehension.

4. Visual Centering. Relating where the reader is in his/her visual space on the page with other objects. Smooth left to right eye movement and line transitions are enabled by efficient visual centering.

Further support for the integration of receiving, processing and remembering information gleaned from the written word or the “amount of information” received by the short-term memory is cited in the research by Dr. George A. Miller of Princeton University. In 1956, he published an article in “The Psychological Review” entitled, The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information. The focus of this article was exploration of the optimal “amount of information” that short-term memory could receive and effectively process at one time. 

After analyzing a variety of experiments on the capacity of people to absorb information, Dr. Miller found that the “amount of information” or “variance” humans most successfully process is “seven, plus or minus two” or in other words, five to nine units, or “chunks,” of information at one time (Miller, 1956). 
Therefore the length of the ReadBar™ in the See-N-Read® Reading Tool is based on Dr. Miller’s “seven, plus or minus two” findings in order to maximize a reader’s visual and cognitive processing.

The color (a blue/gray/mauve) and non-glare design elements of the See-N-Read®reading tool are based on research in the fields of Reading, Dyslexia, Visual and Cognitive Processing, and ophthalmology. Fowler, 2000, Iovino, Fletcher, Breitmeyer & Foorman, 1998; Wilkins, 1996 research discovered that individuals in their studies who were sensitive to glare or print against a light background when reading, more often chose a blue/mauve (end of the color spectrum) overlay to help them as they read. “Blue not only appears to reduce glare, but also the apparent motion of print.” (Fowler, 2000, Iovino, Fletcher, Breitmeyer & Foorman, 1998; Wilkins, 1996). 

The findings of Fowler, Iovino, Fletcher, Breitmeyer & Foorman in 1998 were grounded in A.J Wilkins and I. Nimmo-Smith study conducted in 1984, on the reduction of eyestrain when reading. In their study they reported that “Some children and adults with or without reading problems complain of glare of the black print against the white background. Basically, the background appears to interfere with the print. They may see patterns in the gaps between lines and words, which can be distracting, can cause headache and migraines (sic). (Wilkins & Nimmo-Smith 1984)”



The See-N-Read® Reading Tool helps improve fluency, comprehension, reading rate and accuracy by directly supporting the visual brain pathways (cortical brain center) in three key areas. See-N-Read® helps readers:

1. Gain control of the “field of vision” (a basic requirement for reading)
2. Smoothly and efficiently track left to right (an essential skill for fluency in reading)
3. Effectively use peripheral vision while reading to:


• Accurately interpret contextual cues – improve inference skills 
• Better predict content as they read – improve comprehension skills
• Re-read content for clarity without losing their place – improve regression skills


When readers improve reading fluency and learn how to increase reading comprehension, reading also becomes more fun! The joy of reading and the love of learning are tied to one another. Without strong reading skills, learning across all subject matter, even mathematics, becomes a struggle.
