The Irene Method is one effective way to treat visual perception disorders. This method uses color to create a more harmonized world. You may have heard of these methods if anyone has ever suggested using a color filter over the page when reading to be able to read better and more quickly. This method is proven to work, and if your autistic child is at the maturity level of reading, you may want to try these color filters to see if there is a difference in speed and comprehension. However, it is more likely that your autistic child will benefit from color filters during the entire day, not just when reading.
