This type of therapy works through rapid eye movement. The client receives instruction to move their eyes in particular directions while under the guidance of the therapist. The therapist uses lights, moving objects or even sound to make the client move their eyes in particular directions. While the client is moving their eyes, they are encouraged to focus on their trauma. This combination of eye movement and focus helps the client’s brain to react differently when thinking about the traumatic situation. Ultimately, this allows the brain to change the way it responds to thoughts and memories when they resurface in the future. The client is not necessarily required to discuss their issues in deep detail for this therapy to work well. This type of treatment works well for complex PTSD, PTSD, trauma, painful and difficult memories, anger, anxiety, depression, and phobias.
