If you’ve just started learning about EMDR therapy, you might wonder how and why moving your eyes from left to right can help heal trauma. EMDR, which stands for Eye Movement Desensitization and Reprocessing, is a powerful therapeutic technique that was first developed to treat PTSD (post-traumatic stress disorder). Today, it is used to treat many other trauma-related conditions.
This wider use matters because trauma does not always fit a PTSD label. EMDR can support people with childhood trauma, complex PTSD, anxiety, panic symptoms, phobias, grief, medical trauma, distress after accidents, and stressful life events that still feel “alive” in the body.
Let’s break down how and why this seemingly simple eye movement process works.
What Is EMDR Therapy?
Developed by Francine Shapiro in the late 1980s, EMDR Therapy uses bilateral stimulation typically through guided eye movements to help you recall distressing memories.
You might be curious about the science behind EMDR. The therapy relies on the brain’s natural ability to process and integrate information. During traumatic events, this processing can become stuck or improperly integrated, which causes symptoms of PTSD.
Bilateral stimulation, such as moving your eyes left to right, seems to help the brain reprocess these stuck memories. It mimics your eye movement during the REM stage of sleep, which is also the phase where most of our emotional processing and memory consolidation occurs.
EMDR does not erase memories. It changes how the brain stores them. The event remains part of your story, but it loses emotional intensity and physical charge.
Why Does Moving Your Eyes Help?
Here are a few reasons why moving your eyes left to right help:
- Dual Attention Stimulus: Eye movements create a dual attention stimulus, so you must focus on the traumatic memory and the external movement. It softens the intensity of your emotional response.
- Working Memory: Bilateral stimulation taxes your working memory, making it harder for you to maintain the vividness and emotional intensity of the traumatic memory.
- Neurobiological Effects: Some studies suggest that bilateral stimulation can cause changes in brain activity, particularly in areas involved in emotional regulation and memory processing.
Therapists may also use tapping or alternating sounds instead of eye movements. These methods provide the same bilateral stimulation effect when eye tracking feels uncomfortable. Virtually, many EMDR therapists also use software and guide you through.
How Does EMDR Therapy Work?
During an EMDR session, your therapist will ask you to focus on a traumatic memory while following their fingers. This therapy also works just as well when done virtually. Your therapist will use a software to guide your eye movement. It involves eight phases:
- History Taking: Your therapist gathers detailed information about your history and identifies target memories for treatment.
- Preparation: You learn about EMDR and practice techniques to manage emotional distress.
- Assessment: to identify specific aspects of the target memory to process.
- Desensitization: You focus on the memory while engaging in bilateral stimulation, which helps reduce the distress associated with it.
- Installation: Strengthen positive beliefs about yourself and replace the negative beliefs associated with the trauma.
- Body Scan: You focus on physical sensations to identify and address any residual distress.
- Closure: Each session ends with stabilization techniques to make sure you leave feeling safe and grounded.
- Reevaluation: In following sessions, your therapist assesses your progress and determines if further processing is needed.
EMDR therapy is usually short-term with one or two sessions every week lasting for about 6 to 12 weeks. Your therapist will combine it with a couple more therapies or modalities for a more rounded approach.
What Does Virtual EMDR Therapy Feel Like?
Many people hesitate with virtual therapy, thinking it won’t work as well. But virtual EMDR uses the same eye-movement techniques through software that mimics finger tracking. Therapists may use moving dots, tones, or vibrations to guide your focus. You’ll still follow the eight phases of EMDR but from the comfort of your home. In most cases, clients report the same emotional release and breakthroughs in virtual sessions as they do in-person.
What Happens After EMDR Therapy?
The effects of EMDR therapy can vary based on the person, the memory being processed, and how long that trauma has lived in the body. Still, many clients notice a shift after just one session, enough if it’s minor.
After Your First EMDR Session
You may feel tired, emotional, or mentally drained. That’s normal. Your brain has just done a lot of emotional work, and your nervous system is adjusting. Some people feel lighter. Others report vivid dreams, subtle shifts in body tension, or emotional waves they hadn’t felt in a while.
After a Few Sessions
By session three or four, most people begin to feel changes in how they remember the event. The image may feel less sharp. The emotions feel more distant. You might start to say, “It still happened, but it doesn’t control me the way it used to.”
You might also notice:
- Less reactivity in your body when thinking about the memory
- Fewer emotional triggers in daily life
- Clearer connections between past trauma and current coping habits
- More space to think before reacting in stressful situations
Some people feel immediate breakthroughs. Others feel a steady shift over several sessions. There’s no one-size-fits-all timeline, and your therapist will guide the pace based on your nervous system’s readiness.
Hydration, rest, gentle movement, and grounding exercises support recovery after sessions. Avoid emotionally intense activities on the same day when possible.
How Will You Know When You’re Done?
EMDR therapy ends when:
- The distress linked to the memory is gone or very minimal
- Your body no longer reacts when you recall the memory
- You believe a new, empowering thought (e.g., “I am safe now”) and it feels true
- You can talk about the memory without feeling flooded or dissociated
Your therapist will revisit the original target memory during reevaluation phases. If you feel neutral, emotionally balanced, and physically calm, that’s a good sign you’ve completed the reprocessing.
But EMDR doesn’t have to stop after one issue. Many people continue with new memories, attachment wounds, or traumas that show up later in life. It’s a tool you can return to whenever you feel stuck or emotionally overwhelmed again.

Frequently Asked Questions
What makes EMDR vs traditional talk therapy different?
EMDR targets how the brain stores traumatic memory, not just what you think about it. You hold the memory while bilateral stimulation helps your brain reprocess it. Talk therapy often builds insight and coping first, then shifts beliefs over time. EMDR can move faster when trauma keeps replaying in the body, especially with triggers and flashbacks.
Is there anything you advise or caution before starting EMDR?
Ask your therapist how they assess safety and stability before memory work. Good preparation matters if you dissociate, feel emotionally flooded, or live with ongoing crisis stress. You should also plan recovery time after sessions, since vivid dreams and fatigue can show up.
How do I find a virtual EMDR therapist in Toronto?
Start by checking licensure and scope of practice. Use CRPO to verify a Registered Psychotherapist, or CPBAO to verify a psychologist. Then ask if they have formal EMDR training, plus trauma experience with your concerns. You can also use CAMH resources for safe search starting points.
Is EMDR recommended for first responders, and would it work virtually?
Many guidelines list EMDR as an evidence based option for PTSD, which includes occupational trauma. First responders often carry layered grief, moral injury, and repeated exposure stress, so pacing matters. Virtual EMDR can work when the therapist builds strong stabilization first and sets clear safety steps. Ask about dissociation screening, between session supports, and how they handle acute triggers after sessions.
