Software solutions can achieve the same effect on the computer screen. Here are some options that you can try, many of which are free. Colored lenses provided by optometrists and vision specialists to treat reading problems are not the same as the Irlen Method. These professionals do not have the correct diagnostic process for color selection and inaccurate color selection can result in worsening symptoms. Is it Dyslexia or Irlen Syndrome? Despite the research suggesting colored overlays is not an effective treatment for dyslexia, colored overlays continue to be used as an intervention to improve reading skills of individuals with dyslexia. The authors of this study sought to add to the literature regarding the effect of colored overlays on reading fluency for individuals with dyslexia, as well as extend the literature by investigating the effectiveness across age levels, ranging from 7 to 32 years old. When colored overlays were ineffective, the authors then investigated the effects of research-based reading interventions on oral reading fluency for the same individuals. The results of this study indicate that colored overlays either had no effect on words read correctly per minute (as was the case for Emily and Lindsay) or resulted in a decrease in words read correctly per minute (as was the case for Lisa). These results support the previous research demonstrating colored overlays have little effect on reading fluency (e.g., Ritchie et al. 2011). Further, whereas previous research has suggested that colored overlays have greater effect on children with dyslexia than adults (Singleton and Trotter 2005; Singleton and Henderson 2007), this study suggests that colored overlays may have a deleterious effect on adults. Although colored overlays did not improve reading fluency for the children in this study, the adult’s performance actually worsened with the colored overlay intervention. For example, in a rigorous double-masked design (in which neither the subject nor the experimenter knew the true diagnosis and prescribed colour) researchers from the University of Edinburgh reported that Irlen coloured overlays had no immediate effect on reading ability.
Visual dyslexia is a reality for about 30% of the population. It can cause headaches, migraines, reading discomfort and distortion of text that can vary from mild to so severe that reading is seriously impaired or even prevented. Fuchs, L. S., & Fuchs, D. F. (2011). Using CBM for progress monitoring. Washington, DC: National Center on Student Progress Monitoring, American Institutes for Research. Retrieved from http://www.studentprogress.org/library/Training/CBM Reading/UsingCBMReading.pdf To truly determine if your child suffers from light sensitivity, or Irlen Syndrome, it is recommended that they be screened by a professional trained in the Irlen Method. Bright blue light can also improve auditory attention, suggesting that the effects of light on alertness and attention are automatic and not mediated by conscious visual perception. Rather they are mediated by this retino-hypothalamic synchronising system. Learning aids for dyslexia can come in different forms. Such as coloured paper and coloured overlays can help with reading and writing difficulties by easing visual stress, improving reading rate and comprehension, and making reading and writing feel far more comfortable. Pencil grips can help if you feel that you struggle with your handwriting or hold your pencil correctly. Dictaphones are perfect for recording important information in case of forgetfulness and they alleviate the stress of reading and writing if you’re not confident in those areas.Hoyt CS.

The DRT has carried out a randomised control trial that showed that in suitable dyslexic children, wearing blue filters for 3 months improved their reading age by an amazing 9 months. Blue light therapy has also been shown to help people with sleeping problems, to improve alertness during night shift work and to help overcome jet lag. This probably also works on the suprachiasmatic nucleus to alter the timing of diurnal rhythms. We found that children whose reading benefitted from wearing blue filters during the day also often reported that their sleeping patterns had improved, and we showed that this was probably due to an effect on the SCN; at night secretion of the sleep hormone, melatonin, which is also under the control of the SCN, can be inhibited by just 15 minutes of blue light ie blue light can reset the SCN rhythms to improve sleeping. I’ll often get asked if these letters being transposed and reversed diagnoses dyslexia. The simple answer is ‘no’. As a stand alone difficulty we would not say this is dyslexia, yes it can be a characteristic of that, along with other clusters of difficulties. However I would always strongly recommend a full diagnostic dyslexia test and certainly a visit to a behavioural optometrist. This light sensitivity can cause symptoms that look similar to dyslexia and Irlen Syndrome experts suggest that some people are incorrectly diagnosed with dyslexia when in fact, they have Irlen Syndrome. The vision screening that most children undergo at school entry (age 4 to 5) is only a test of whether a child can see clearly in the distance. It is not a comprehensive assessment of eyes or vision and does not test any of the functions required for clear and comfortable vision when reading. For this reason, every child should have a full sight test when they start school, and as frequently as recommended by their optometrist after that.In cerebellar patients he had shown that their unstable vision was due to damage to large nerve cells in the brain, known as visual magnocells, that are specialised for detecting movement. When these magnocells are not working properly the servo system that keeps your eyes fixed on a letter fails, and so the letters appear to move around. So with Sue he set up a clinic to investigate whether children's visual reading problems were due to the same cause.
Visual dyslexia needs to be objectively observed. Most sufferers are not aware that their experience of reading differs from that of other people. Fortunately, behaviour associated with visual stress can be quite easy to spot. Dyslexia assessor Georgina Smith says that coloured overlays can help people with visual stress as well as dyslexia. When Smith assessed some students, who were experimenting with coloured overlay rulers, the students said that they wanted to try their favourite colours at first. Smith thought that it was best for the student to try every coloured overlay ruler available to them for 10 – 15 minutes before deciding which colour worked best for them.

To make matters worse English is littered with exceptions to the letter-sound rules. Compare bough, dough, lough, cough, enough! After all that effort on reading each word, many children can't remember the words they read at the beginning of a sentence to understand the whole thing.

Myth versus evidence
In people with Irlen Syndrome, colored overlays can improve reading fluency, comfort, comprehension, attention, and concentration while reducing light sensitivity. This is not a method of reading instruction. It is a color-based technology that filters out offensive light waves, so the brain can accurately process visual information. Getting the right color overlay But disagreement among researchers still exists over the mechanisms and theory behind the filters’ effects. And debate still rages surrounding the fundamental issue of which colour is needed to achieve optimal results. Myth versus evidence Wilkins A. Coloured overlays and their effects on reading speed: A review. Opthalmological and Physiological Optics. 2002; 22:448–454. doi: 10.1046/j.1475-1313.2002.00079.x. [ PubMed] [ CrossRef] [ Google Scholar] Many people who experience these issues find that placing coloured overlays onto the printed reading material helps alleviate discomfort and can improve reading efficiency and comprehension. Some people who experience headaches and other forms of visual discomfort have also found improvements from using these overlays.
