Dyslexia and Vision Q&A
Q. WHAT IS DYSLEXIA?
A. The word 'dyslexia' comes from the Greek and means 'difficulty with words'.It primarily affects the skills involved in accurate and fluent reading and spelling. It is believed to be one of the most common learning difficulties although many dyslexics are very bright and often have strong visual, creative and problem solving skills. Many famous and sucessful people are known to be dyslexic.
Q. WHAT IS VISUAL STRESS?
A. Simply explained, Visual Stress ( also known as Visual Dyslexia or Irlen Syndrome) is a sensitivity to visual patterns, particularly stripes.It can occur when a white background appears to interfere with lines of black print and causes difficulties with visual processing of the reading content.
Q. IS VISUAL STRESS THE SAME AS DYSLEXIA?
A. Visual Stress is not the same as dyslexia, but is more common in those who are dyslexic and can occur despite normal vision. It is thought that it affects 12% of the population and 65% of dyslexics. Many dyslexic people are sensitive to the glare of white backgrounds on page, white board or computer screen. This can make the reading of text much more difficult.
Q. WHAT ARE THE SYMPTOMS OF VISUAL STRESS?
A. Sufferers may report movement and blurring of the text. Letters can appear to reverse or change shape. Halos, colours or patterns, sometimes described as 'rivers' or 'worms'. Red, sore eyes and headaches are also frequent complaints. These individuals often have poor comprehension of the reading content and are observed to fidget, move book around, skip words and lines and often rub their eyes and blink frequently. Frustration and low self esteem can occur in children who are under achieving at school due to visual stress, threfore erly diagnosis is essential. The longer it takes to identify and remedy visual stress, the greater the loss of confidence that can result.
Q. MY CHILD HAS DIFFICULTY READING BUT I WAS TOLD THAT HIS VISION IS NORMAL?
A. It is important to remember that normal sight may not necessarily be synonymous with normal vision. reading is a complex task and involves many aspects. Most recent studies found that people with reading difficulties, such as dyslexia, are more likely to have unstable binocular vision at near distance, which means that their eyes have to work harder than usual to maintain alignment and tracking whilst reading and writing. Some of the conventional tests used in routine eye examination may not show this instability in children. SCHOOLVISION binocular vision assessment method with its battery of tests is very accurate and specifically designed for testing children.
Q. IS THERE A CURE FOR VISUAL STRESS?
A. There is no 'cure', but visual stress can be reduced or eliminated by the coloured lenses worn in spectacles. These are prescribed following Colorimetry assessment when the precise tint is selected with the aid of INTUITIVE COLORIMETER, which produces thousands of colour combinations. To achieve best result it is essential to investigate and correct any binocular vision instability before undertaking colour assessment. The sucess rate in our practice is around 80%. Degree of improvement differs - some individuals reach up to 150% increase in speed of reading, some about 20% due to other non-visual learning difficulties. Very often children move up several reading levels within few weeks.
VISUAL STRESS assesments are available at TAYLOR BIDDLE OPTICIANS and include a full binocular SCHOOLVISION assessment and COLORIMETRY. Please enquire about further information.Next
