Can ChromaGen Glasses Really Cure Dyslexia?

                                               Image offered at Chromogen Website 
If ChromaGen glasses can cure dyslexia, this implies that the root cause of this condition lies in the visual domain.  However, recent research, by Guinevere Eden, Ph.D. at George Washington University Medical Center suggests that visual processing weaknesses are not the cause of dyslexia.  Nonethless, some individuals with dyslexia also report visual distortions when reading, and for those who suffer from the illusion that words appear to move on the page and also experience headaches, fatigue, and nausea when reading, these glasses may warrant a second look. 

What is the History of ChromaGen Glasses

The ChromaGen website reports that what began as an optical corrective solution for color blindness, soon became a tool for some individuals with dyslexia when they reported a reduction in certain symptoms.  As a result, ChromaGen now offers a series of 16 lenses that are designed to help children or adults who have visual reading disorders associated with dyslexia.

How Do the Glasses Work:

According to ChromaGen, for some individuals, the eyes do not work together properly.  The visual information that travels along the brain’s neurological pathway is imbalanced.  The creators of ChromaGen glasses claim that colored lenses change the wavelength of light going into the eyes so that the speed of the information is altered.  By placing different colored filters over the eyes, the glasses can balance the information traveling to the brain.  Dr. Harris, who developed the ChromaGen lenses, also purports that 90% of individuals with dyslexia, that report visual distortions, benefit from their product.

What are the Pros
1.   ChromaGen glasses are noninvasive and could offer a quick fix for some visual processing symptoms.
2.   ChromaGen glasses are approved by the FDA.
3.   ChromaGen glasses offer a 90 day, no questions asked, money back guarantee.
4.   There are no reported side effects.

1.   ChromaGen glasses are expensive at $150.00 for a screening and $750-$1200 for a pair of glasses.
2.   ChromaGen glasses are not covered by insurance.
3.   ChromaGen glasses only address one specific symptom that effects only some individuals with dyslexia.
4.   Although the ChromaGen website offers plenty of written and video-based testimonials about the benefits of their product for individuals with dyslexia, they still need to back their claims with rigorous, quantitative research. 

If you are still curious about ChromaGen glasses, they offer a questionnaire on their website that can help you determine whether you or your loved one is a candidate for this technology.  Here is a link to the survey:

You can also view some videos about the Chromagen lenses at the following link:

In conclusion, these glasses may help some individuals with dyslexia to correct a specific visual processing issue, but it’s definitely not a cure for all the symptoms associated with this condition.  Although, there are many testimonials for this technology, one must consider the placebo effect.  But, if you really want to know for yourself, and money is not an issue, why not give it a try.  If you have any experience with these glasses, I would love to hear your feedback.

Back to School: Planning, Time Management and Organization Instruction

Many teachers can not fathom how apparently simple tasks such as using an agenda or turning in an assignment can be very difficult for some of their students.In fact, many students need comprehensive instruction and scaffolding to learn to plan, manage time, and organize.Executive functioning, which encompasses these skills is the last part of the brain to fully develop, and in actuality, does not reach maturation until students reach their early 20's.
How Hard Can it Really Be to Plan, Manage Time and Organize? I have to admit, when I first started working with students that struggled with executive functioning, I was surprised how challenging planning, time management and organization could be for some of my young, bright learners.What seemed to be clear and obvious was obscure, taxing and problematic for them.
These Students are Often Misunderstood: Instead of compassion and strategies, students that have difficulties with executive functioning are often intimidated, harassed and m…

Help for Struggling Readers: Creating Your Own Color Overlays

You can create your own overlays by using whole sheets or cutting strips of transparent, colored report covers, dividers or overhead projector film. 

Step one: Buy a variety of colorful transparent sheets.  You can use - color, transparency filmcolor, transparent report covers (plastic)color, transparent dividers (plastic)

All of these options can be found at office supply stores.
Step two:  Everyone is different.  Let your students try out the different colors and see which one they like the best. Step three:  For some students, keep whole sheets so that students have the option of changing the background color of the entire page of text.  Other students might like a thin strip of color, as it can help with tracking from one line to the next.  I make them a variety of lengths and widths, and often let students decide for themselves.  Note: The strips also make wonderful book marks. 
Step four (optional):  Place a plain sticker on the end of the overlay strip or the bottom of a whole sheet…

10 Free Ways to Improving Visual Tracking for Weak Readers

While reading, tracking across the page from one line to the next can be tricky when the text is small, but for students with dyslexia or weak reading skills, it can be a problem regardless of the font size. 
What Exactly is Tracking? Tracking is the ability for one's eyes to move smoothly across the page from one line of text to another. Tracking difficulties happen when eyes jump backward and forward and struggle to stay on a single line of text.  This results in problems such as word omissions, reversals, eye fatigue, losing your place while reading and most importantly it can impact normal reading development.  
Can Tracking be Improved? Tracking can be improved by strengthening eye muscles as well as getting your eyes and brain to work cooperatively.  There are three eye movements that need to be developed:   Fixations: The ability to hold one's eyes steady without moving off a target.Saccades: The ability to jump to new targets that randomly disappear and reappear in a dif…

Following Directions: How Do I Teach this Skill?

Learning to follow directions is a crucial milestone in any student’s learning program.  It is the foundation of learning and difficulties in this area can impact a student’s ability to take notes, follow a sequence of steps, as well as show their knowledge on written assignments and even multiple-choice tests.

Even if a student is listening carefully or reading and rereading text, it doesn’t mean that they will succeed at following directions.  Weaknesses in attention, executive functioning, and language processing (both auditory and visual) can present as great obstacles for these students.  So what can be done about this?

We need to teach students how to follow directions.  They need to learn the subtleties of linguistic cues.  They need to learn to carefully analyze each word and then know how to decipher what it all means.

Whether it involves listening comprehension (auditory, receptive language) or understanding written directions (reading comprehension), there are a number of…

15 Ways to Nurture a Growth Mindset in the Classroom

How can we nurture resilient, active learners that embrace challenging academic material and become successful lifelong learners? Carol Dweck suggests that what we need to do is help students shed a fixed mindset and adopt a growth mindset. What's more, Dweck contends that developing a growth mindset will also result in less stress and a more productive and fulfilling life. 

What is a Fixed and Growth Mindset?
In a fixed mindset, students believe that their abilities are dependent on fixed traits that can not be changed such as intellect or talent. Individuals that think this way, often cultivate a self-defeating identity, feel powerless, and many struggle with a sense of learned helplessness. In contrast, students with a growth mindset accept that abilities and aptitude can be developed with persistence and effort. As a result, these individuals are not intimidate by failure, because they realize that mistakes are a part of the learning process. They continue working hard despite a…

Remediating Dyslexia with Orton Gillingham Based Reading Games

Students with dyslexia and other language-based learning disabilities often learn differently and require an alternative approach to learning basic reading.  What's more, these young learners are working full tilt while sitting in the classroom and by the time they get home and have to complete their homework, they are mentally spent.  As a result, tagging on remedial reading lessons to a cup that is already overflowing can be enough to turn these kids off to learning altogether.

How Do We Help These Students Learn the Core Skills Needed to be Successful Readers?
First, use a remedial program that is backed by time, testimonials and research.  The Orton-Gillingham approach to reading is a well-established and researched approach that offers a multisensory, sequential, incremental, cumulative, individualized, and explicit approach.  There are many programs that are available.  Click here to learn about a selection of these programs. Second, employ an individualized approach as each …

Improving Spelling for Students with Dyslexia

Not all students require the same remedial process even though they struggle with the same academic difficulties.  Diverse combinations of cognitive processing weaknesses and deficits can unite to create the "perfect storm" that can cause challenges with reading, math, writing, spelling and more.  In fact, no two students have the same cognitive profile, so to provide the optimal solution, one needs to consider both a student's strengths and weaknesses when designing a remedial approach.  

Occasionally, I like to present the questions emailed to me from parents and teachers.  This week, I will share an email that I received from a parent in England as well as my response.

Email received: 

Hi there:
Love the website!
Our son (age 8) is dyslexic and we have been told that he has a good visual memory (so he can easily spot a correctly spelt word and can even easily distinguish the correct meanings of similar sounding words e.g. sea and see). However, he has poor memory retrieval…

How Can I Improve my Executive Functioning?

Executive functioning, or what I like to call the conductor of the brain, is the process of the mind gathering together and making sense of all the information we receive from our instruments or senses.  Helping us to create meaning from what we see, hear, touch, taste and experience, executive functioning also allows us to focus our attention, think about new information, and make connections to what we already know.  
Many teachers and parents have trouble understanding how simple tasks such as remembering appointments, using an agenda or turning in assignments can be difficult, but unfortunately these and other similar tasks can be extremely challenging for some individuals.  However, the good news is the part of the brain that manages executive functioning, which is called the frontal lobe, continues to develop through high school and college.  Therefore, many kids that struggle with executive functioning can significantly improve their abilities.
You Might have Executive Functionin…
