Many of us assume that everyone sees print, people’s faces and the environment around us, exactly the same way. People with perceptual problems, even with perfect visual acuity, can perceive print like the examples in the interactive picture below.
These distortions can occur every day, regardless of how hard you try. People with this type of perceptual issue have never known anything else, so they believe everyone else perceives things the same way as them.
Perception is a brain function and is different to vision, which involves eye function. In people with perceptual difficulty, the brain is mis-processing images coming from the eyes, causing these distortions. It has nothing to do with intelligence.
The word dyslexia is associated with a variety of reading and perceptual problems. Symptoms of Perceptual Dyslexia include poor spelling, writing, inefficient reading, sore eyes, headaches, glare sensitivity and depth perception difficulties. The condition is genetic, however the symptoms and severity can be different in each individual.
Perceptual Dyslexia is not an optical condition. For some, it can co-exist with non-related visual acuity conditions.
Helen Irlen’s colour lens technology corrects the way the brain is mis-processing specific frequencies in the light spectrum. Irlen Lenses can therefore, provide immediate assistance. Where necessary, a prescription from your optometrist can also be included. The result is a miracle for some, an important part of the puzzle for others.
