Colored overlays are designed to help alleviate reading disabilities caused by visual processing disorders by emphasizing text and giving an illusion that the text is on a colored background. They work by changing each color's wavelength, revising how fast signals are sent from the eye to the brain.
Individuals with a diagnosis of SSS may have difficulty fluently reading a text or may quickly become fatigued while reading. Colored filters are intended to relieve these issues and improve reading performance.
These glasses help dyslexic patients see texts and words more clearly, which can help speed up their reading pace. ChromaGen lenses are reported to reduce the visual distortions that dyslexic patients see. This is done by altering the wavelength of light that enters their eyes.
Coloured overlays reduce the perceptual distortions of text that children sometimes describe. They enable some children to read text more fluently and with less discomfort and fewer headaches. It is important to assess the effects of a wide range of colours because individuals do not all benefit from the same colour.
Use dark coloured text on a light (not white) background. Avoid green and red/pink, as these colours are difficult for those who have colour vision deficiencies (colour blindness). Consider alternatives to white backgrounds for paper, computer and visual aids such as whiteboards. White can appear too dazzling.
Color Cueing in Multisensory Programs
Because of this multisensory phonics programs sometimes use color cueing to help a child who has dyslexia. This color cueing allows children with dyslexia to have a visual reminder to aid them in identifying the different phonological features.
It is therefore likely that blue light, selected optimally to recruit melanopsin RGCs, will have the greatest effect on improving alertness and concentration and may therefore be the best for remediating the impaired attentional responses seen in dyslexia.
Coloured overlays, also known as tinted overlays, are thin sheets of coloured plastic that can be placed over text to help improve reading. Its purpose is to act as a reading aid for those with visual stress and learning difficulties.
We know that certain cells in the Visual Cortex are colour sensitive and therefore by placing a colour in front of the eye; the pattern of excitation can be changed. In other words the colour will help to slow and calm these cells therefore quietening the pattern and reducing the Visual Stress.
Studies have found that students with dyslexia may benefit from using different color paper or paper overlays because it reduces stress on the eyes.
Primary benefits – Pat Wyman's research
She suggests that the overlays help in making the print clear up (by helping the reader in actually viewing what one reads more easily) and lessening the adversity of the visual perceptual problems like Dyslexia.
To date, research on the efficacy of coloured lenses for dyslexia has failed to do this. Put simply, it seems unlikely that wearing coloured lenses would directly harm children who have dyslexia.
Coloured overlays can significantly reduce the symptoms of visual stress by filtering out the wavelengths that over-stimulate the visual cortex.
Second, while it is true that a large number of individuals with reading problems that have been diagnosed as dyslexia can be helped with colored overlays and lenses, this is not because color can help dyslexia.
Are blue overlays helpful? Coloured overlays are usually helpful to a student when they are experiencing visual stress. You can usually identify visual stress in relation to reading when reading is slower, inefficient and erroneous.
Bright white slide backgrounds can make text harder to read; choose an off-white or cream background instead. Text should be dark, with lots of space around the letters. Alternatively, a dark background with white text also works well.
We observed that children with developmental dyslexia found it easier to read along when audio was synchronized with text highlighting, particularly for the highlighting style that used a blue band for whole sentences.
The results show that using certain background colors have a significant impact on people with and without dyslexia. Warm background colors, Peach, Orange and Yellow, significantly improved reading performance over cool background colors, Blue, Blue Grey and Green.
The 4 types of dyslexia include phonological dyslexia, surface dyslexia, rapid naming deficit, and double deficit dyslexia. Dyslexia is a learning disorder where the person often has difficulty reading and interpreting what they read. It is neither infectious nor brought on by vaccinations.

Dyslexie font is a typeface – specially designed for people with dyslexia – which enhances the ease of reading and comprehension.
Pink sunglass lenses can help reduce eye strain and enhance visual clarity. They are also great to wear while driving, providing heightened road visibility due to their ability to boost contrast. In fact, a lot of the same benefits you get from wearing red sunglasses you'll also get from pink glasses as well.
The overlays work as light filters, reducing contrast and can also be used as a ruler or a guide line to help track the writing in a notebook or pad, allowing the reader to follow each sentence. They can also support as a handy bookmark tool.
Taken together, these results suggested that the green filter improved reading performance in children with dyslexia because the filter most likely facilitated cortical activity and decreased visual distortions.
