Assessment of Silent Reading Efficiency


“The Decline of Comprehension-Based Silent Reading Efficiency in the United States: A Comparison of Current Data with Performance in 1960” appeared in Reading Research Quarterly in 2016. While there are endless debates about reading pedagogy, there is consensus that the best way to assess silent reading efficiency is by measuring eye movements. Continue reading


Patient H69 The Story of My Second Sight


Vanessa Potter

Vanessa Potter experienced a brain injury from a sudden inflammatory response triggered by a rare autoimmune disease. Within two days she went completely blind and lost much of her feeling and motor skills. She regained her sensation and motor abilities and partially regained her sight during an extended period of recovery. Continue reading

Plasticity in Sensory Systems

2011 International Conference on Plastic Vision

Edited by Jennifer K. E. Steeves and Laurence R. Harris

The term “plasticity” in neuroscience means that the brain can change and discoveries over the last couple of decades have proven that we retain a degree of neuroplasticity into old age. This volume is a collection of papers from the presentations at the meeting. None of the scientists are optometrists but all of their research relates to vision development and vision therapy. Visual skills and the processing of visual information develop through experience and can be modified through directed, intensive rehearsal. This happens as people improve at a craft, hobby, music, art, job, or sport. Visual skills and visual processing can also be developed through vision therapy. The following excerpts are taken directly from the scientific papers. Continue reading

RightEye: Computerized Assessment of Eye Movements

We have used technology to evaluate eye movements for decades. RightEye is revolutionary technology for recording and analyzing the movements of each eye while tracking targets presented on the screen of a specialized lap top computer. Sensors within the lap top monitor the position of the head and eyes while tests are administered that would normally be assessed and recorded primarily through observation. Movements are recorded as the patient follows targets that move horizontally, vertically, and in circles. Eye movements are also tracked as the patient shifts gaze between targets that are separated horizontally, targets that are separated vertically, and while reading material that is appropriate for their reading level. This assesses their eye movements at their most efficient level of reading. The movements are recorded and compared to norms.


These movements, which are critical for efficient visual function, cannot be assessed with this degree of precision without RightEye technology. The analysis displays the movements graphically. It also allows the movements to be replayed so the movements can be observed in the sequence in which they occurred. This information augments our ability to determine the degree to which eye movements are contributing to problems in reading, attention, and comfort and to develop effective treatment plans.


Vision is a sense, but like touch, controlled movements are critical. We must Look to See. The quality of our eye movements determines the quality of our visual input. Input that is not clear and coordinated binocularly (convergence insufficiency), input that is missing because it is skipped, and input that is out of sequence compromises visual processing and its interpretation. Testing visual perception, reading, or attention and making decisions based on the results can be misdirected without a thorough evaluation of ocular motor skills.

Reading is complex. Many visual skills are involved which must be coordinated with language skills, phonics, and prior knowledge. Poor readers often skip words, read words out of sequence, misread words, and experience garbled input due to poor focus or the lack of precise binocular alignment. Their visual processing speed may also be slow and out of synchronization with their other abilities. Their visual system may not have adequate stamina to maintain visual efficiency for extended periods of time. Visualization is necessary to develop sight vocabulary and to simulate real experiences from the words on the page and to store the simulation for future retrieval. These visual skills are not innate. There is innate potential but the skills must be developed and rehearsed to become automatic and applied. Ineffective visual function can rob attentional resources needed for comprehension, referencing, and storage and to make reading enjoyable and interesting.

Faulty visual skills cause faulty rehearsal interfering with the progress anticipated based on a child’s intelligence and environment. This can lead to the child’s frustration and frustrate those who are working with him, all of whom care and all of whom appear to be doing the right things. Visual skills that are inadequate for school, work, and avocations have been developed through optometric vision therapy for decades. RightEye builds on this background as efficient visual skills become increasingly important in the visually intensive world of the 21st century.

VT As Part Of A Natural Approach To Health

The VisionHelp Blog

Tusk Health CoverIt’s always good to see nice endorsements of vision therapy from health care providers outside of our profession who “get it”.  This one comes from Yael Tusk of the Jerusalem Center for Natural Health, a source for holistic health counseling and treatment in Israel.

Regarding solutions for ADHD Yael writes: “Vision problems that cause ADHD symptoms are rarely diagnosed by a regular optometrist and are therefore often overlooked.  Anyone with reading problems, learning problems, or ADHD symptoms may have an undiagnosed vision problem … Many people have reported great improvement in their learning, reading, and concentration after receiving vision therapy.”
