    “I am a MD/PhD student who just got diagnosed with Irlen Syndrome. I have been using my overlays, and it has changed my world. My overlay has allowed me to quickly and efficiently read highly complex scientific papers and textbooks. I want to increase recognition of Irlen in the medical community."

    Kate Fraiser’s son has completed his PhD, and she called to say that he could not have done this without his Irlen Spectral Filters. Kate used to call him her Salvador Dali reader as words dripped (fell) off the page. He could not see anything on the page. Both Kate and her husband wanted to say “thank you for saving our son.” Now, they have a 6 year old grandson who needs to be tested for Irlen as he is complaining that words are moving.

    "I had a great response from the Irlen Overlays. I cannot thank you enough for what you have done for my life; I don’t know what I was missing. This has had such a calming effect and has improved my eye health. I enjoy my Irlen Filters and I cannot thank you enough."

    In Memorium

    We lost one of our own when Irlen Screener Heidi Yellen passed away on August 27, 2017. Heidi was a screener for more than a decade. She was so passionate about Irlen that she talked her husband, Dr. Drew Yellen, into becoming an Irlen Diagnostician. Heidi was a tireless advocate and one of the finest people I have known. She is sorely missed. I want to share one lingering memory of Heidi and Drew dancing the two-step at the Irlen International Conference held in Houston, Texas, in 2015. They stood out amongst all the other couples as they glided seamlessly across the floor in perfect step and harmony. Heidi may be gone, but she will forever live in our hearts and memory. We pay tribute to our brilliant, elegant, and kind friend and consummate professional whose inner light will continue to inspire all of us and those whose lives she touched for many years to come.

    Q & A: We Answer Your Questions

    Question: Hello. I have been using peach overlays for many years. I was tested in a local center when I was at college; am now doing a lot of paperwork and form filling as part of my job. However, I cannot write on an overlay. I am wondering if I was to use peach paper, would this do the same as my peach overlay that it helps with reading?

    Answer: The colored overlay and the paper color you would write on would be the same. However, if you are working or sitting in meetings under fluorescent lights or having to look at whiteboards or power points, I would suggest that you consider Irlen Spectral Filters, which are worn as glasses. This would simplify your life as you would no longer need a colored overlay or colored paper.

    Question: I listened to your intro video on Irlen Syndrome, and I was wondering if I could get some more information. I have had severe light sensitivity for years which was investigated by my eye doctor but could not really be explained. I've also been diagnosed with ADHD and dyslexia as an adult and suffer from chronic migraines. My eyes will hurt and my head will hurt when I read, the page swims, and the words move in waves. I have glasses, but I find that I cannot see at all in really bright light or fluorescent light. I was wondering if it is possible to get Irlen glasses with a prescription or if there is anything that is possible for this? I would love to try them out. I love to read, but it is so hard to do and usually makes me feel terrible. It would be so amazing to just be able to read normally.

    Answer: All of your difficulties sound like those we have helped hundreds of thousands of times with the Irlen Spectral Filters. If you wear prescription glasses, your special and unique filter color is added to your prescription. I am so sorry you have had to suffer for so long and have only recently heard about the Irlen Method. Let me know how your life changes with your Irlen Spectral Filters.

    Smith County Champions for Children Helps Families Grapple with Little Understood Reading Disability Irlen Syndrome

    Irlen Syndrome can be scary for children learning to read. Their eyes process light differently and make words appear to be floating off of the page. In recent years, understanding of the condition has expanded. It is estimated that as much as 15 percent of the general population has the condition, according to the Irlen Syndrome Foundation. Smith County Champions for Children helps families determine if their child’s reading disability is a result of Irlen or other conditions.

    Child Development Specialist Debbie Lauman said dyslexia and Irlen often go hand in hand or share symptoms, which can make diagnosis difficult. “Irlen is how the brain processes light,” Lauman said. “A person who is completely dyslexic can see things up to 37 different ways. With Irlen, things move.” Treatment for Irlen can be as simple as finding the right tint of a colored overlay to help one’s eyes focus. Clear plastic sheets are placed over the text and the movement of the writing is reduced. Parents meet with school personnel after diagnosis to request an accommodation for the student.

    Brooklyn White was first diagnosed with Irlen in 2016, which led to a dyslexia diagnosis in February. Her mother, Joni, said Brooklyn already is noticing a difference in her behavior and schoolwork. “It was like I was sitting on a boat with a child reading a book,” Joni said. “When she would look at a book before, it was moving and that made her want to move, too.”

    During testing, Joni noticed a drastic change come over her daughter when Lauman held up a rose colored overlay. She said Brooklyn lit up and stopped moving around as she finished the testing. “It was kind of scary when things were moving, and I couldn’t read,” Brooklyn said. With the Irlen diagnosis out of the way, Lauman was then able to focus on the other issues Brooklyn was having with reading. “People who have really severe Irlen may not see the world the way it is,” Lauman said. “It can make kids agitated if everything is moving.”

    Because Irlen is hereditary, Joni had an inkling that Irlen may have been a possible cause of her daughter’s problems. Joni was not diagnosed until she began college. With Irlen, symptoms may not be apparent. Students perform visually intensive activities for a period of time. Fluorescent lighting also can agitate symptoms. Lauman said it is important to try to catch Irlen as early as possible. Once a child begins reading, they can be tested. “If you struggle with reading, it affects every other part of your education,” she said. “Everything is a tool in our toolbox. If they have both Irlen and dyslexia, some of the symptoms tame with treating Irlen.”

    Not only are Brooklyn’s grades improving, she also is seeing a boost in self-confidence. Brooklyn said she now feels like she is the same as other students. She no longer worries that she is different or something is wrong with her because she struggled to read. For more information, visit Twitter: @TMT_Cory

    Being an Irlen Warrior

    We want to give a big shout out to Jennifer Owen, an Irlen Spectral Filter wearer, who is doing so much to increase Irlen awareness. Jennifer writes: “I never imagined that I would be educating government officials about Irlen Syndrome and the issues that those with Irlen face on a daily basis. During this year, I gave a talk about Irlen Syndrome at my local Rotary Club. I started to educate the local election candidates where I live about Irlen Syndrome and am working on changing the voting paper where I live from black text on white background to black text on cream background. I was asked to write a piece about Irlen Syndrome for Learning Disabilities of Wales and for a company where I live. I am helping a youth club and a company learn about Irlen Syndrome. After a presentation to the Parliament, at which some Irlen Directors and I participated, the Welsh Assembly is considering having exams on coloured paper for those with Irlen Syndrome. Finally, my MP Gerald Jones is on the front bench for the Labour party which means Irlen now has a voice in Parliament well as the Welsh Assembly.”

    Shape Young Minds Through Sensory Environments
    During the first three years of life, children experience the world in a more complete way than children of any other age. The brain connects to the world through its system of sight, hearing, smell, touch, and taste. This means that young children develop their social, emotional, cognitive, physical, language, and cultural skills through their sensory experiences. This article provides practical ways to create a sensory environment for your young child. The piece is here:

    Strategies for Improving Your Sleep
    Maintain a regular sleep schedule. Go to bed at the same time each night and wake up (regardless of how much sleep you got the night before) at the same time each day, including on weekends.

    Your bedroom should be comfortable. Control the temperature so that your room isn’t too hot or too cold. Also, keep your room as dark as possible while sleeping.

    Don’t take naps! This is one of the biggest mistakes you can make if you have trouble sleeping. Daytime naps will make the nighttime sleep cycle disruption worse.

    Use sounds. Soothing nature sounds, soft music, wind chimes, white noise makers, or even a fan can induce a very peaceful mood and lull you to sleep.

    Technology-free bedroom. Take computers, video games, the TV, and cell phones out of your bedroom and turn them off an hour or two before bedtime to allow time to “unwind.”

    Avoid a full stomach. Try not to eat for at least two to three hours before going to bed. Regular exercise. However, don’t do vigorous exercise late in the evening as it may energize you and keep you awake.

    Don’t drink any caffeinated beverages and avoid chocolate, nicotine, and alcohol in the late afternoon or evening. Although alcohol can initially make you feel sleepy, it actually interrupts sleep.

    Move the clock so you can’t see it. Don’t toss and turn. If you are unable to fall asleep or return to sleep easily, get up and go to another room to do something relaxing until you feel more tired.

    Study: Mixed Results for Holding Students Back
    Students who are held back in third grade because they do not meet achievement benchmarks may experience some positive results, such as higher GPAs, according to a study of almost one million students. Researchers, however, say the findings overall show mixed results.

    Preemies have increased survival but developmental delay risk persists
    French researchers found that rates of two-year survival and survival without sensory or neuromotor disabilities among infants born from 22 weeks to 31 weeks of gestation rose by 6% and more than 7%, respectively, between 1997 and 2001. However, the findings in The BMJ showed that 50.2% of those born at 24 weeks to 26 weeks, 40.7% of those born at 27 weeks to 31 weeks and 36.2% of those born at 32 weeks to 34 weeks scored below average in a test assessing neurodevelopment.

    Digital Vs Print Reading Formats
    The benefits of digital versus print reading formats are unclear, according to an analysis published in the Review of Educational Research. Researchers found format had little effect when reading to get the “gist” of a text, but format can have an effect when reading for detail or comprehension. There’s some good evidence that readers seem to process longer texts for understanding better in print than digitally, but beyond that there are a lot of question marks, concludes the review, which was published online in July in the Review of Educational Research.

    Study: 51% of Parents Support Delayed School Start Times for Teens
    Fifty-one percent of parents said they supported later school start times for their adolescent children, researchers reported in the Journal of Clinical Sleep Medicine. The findings, based on a C.S.
