Eye and vision techniques are alternative approaches based on physical eye movement and visual perception.
Some are dedicated to improve the way we process visual information such as the Irlen Method, while others are mainly dedicated to improve eyesight such as the Bates Method. Another well-known method uses eye movement as a way of stimulating the brain in the processing of traumatic memories. This approach is called EMDR (Eye movement desensitization and reprocessing).
Finally, color and light therapy focuses on visual perception and brain stimulation.
