RAINBOW LENSES

for VISUAL DYSLEXIA

Reading is one of the most important skills for children to acquire. Reading has a fundamental impact on basic skills in the overall learning process such as counting, writing understanding and processing sentences. It is essential in tulle interactions in the classroom, school and other environments. Unfortunately, reading difficulties are common in children especially in the elementary school age.

Those who suffer from reading disorders from an early age often do not catch up with time and carry their problems with them throughout their school careers. Behavioral problems and unwarranted absences in secondary school often resultanp caused by frustration due to failure and difficulties in reading. Therefore, it is important to be aware of existing and easily applicable methods that can help children improve reading skills and reduce their stress. Reading involves complex visual and cognitive processes. Printed text is a set of letters dispersed on horizontal lines; sometimes the repetition of groups of letters can causaer abnormal visual effects, such as illusory colors, sparkles, and vertical movements throughout the body of the text. These illusions are frequently accompanied by somatic reactions such as nausea, eyestrain, headaches, and reading fatigue. Readers who are affected by these discouraging symptoms may, for example, complain of the "blinding whiteness" of the page and the feeling that the letters are "moving," "tipping over," and "blurring."

These unpleasant experiences are referred to as visual stress. Visual stress refers not only to the perceptual distortion and difficulty that can be elicited while reading, but also to similar experiences in other environments where stripes, dots, repeated geometric patterns, or flickering lights appear uncomfortably. Looking at television, computer screens, or even whiteboards can be visually stressful in these cases. Visual stress is also called Meares-Irlen Syndrome, or Scotopic Sensitivity, and is also often reported as Visual Dyslexia. This disorder is believed to be caused by a specific wavelength within the color spectrum that over-stimulates certain parts of the visual cortex, disturbing the perception of the image of black text on a white background. Changing the colored background to a hue that filters out the disruptive wavelength can drastically improve aspects of visual perception involved in reading and writing. When a person identifies the right filter tint, attention time, reading speed and fluency, and text comprehension can improve.
