Eye Movement Therapy in EMDR

What is eye movement therapy?

Eye movement therapy is the foundational bilateral stimulation (BLS) technique used in Eye Movement Desensitization and Reprocessing (EMDR). Developed by Francine Shapiro in 1987, it involves the client tracking a visual stimulus — typically the therapist's fingers, a hand-held pointer, or a light bar — moving horizontally across their field of vision. It is the most researched form of bilateral stimulation and remains the method most closely associated with EMDR therapy.

How it works

During eye movement therapy, the therapist guides the client to follow a moving target with their eyes while holding a distressing memory in mind. The rapid saccadic eye movements engage the visuospatial sketchpad component of working memory. Because working memory has limited capacity, the dual task of tracking the visual stimulus while recalling the memory competes for resources, reducing the vividness and emotional intensity of the memory. Over repeated sets of eye movements (typically 20–30 back-and-forth cycles per set), the memory becomes less distressing and can be reprocessed with more adaptive beliefs.

When therapists choose this technique

Eye movement therapy is used as the primary bilateral stimulation method in standard EMDR protocols for PTSD, anxiety, phobias, and other trauma-related conditions. It is typically the first-choice BLS method in clinical settings where the client can comfortably track visual stimuli. Therapists may switch to alternative BLS forms if the client has visual impairments, finds sustained eye tracking uncomfortable, or experiences headaches or dizziness during the process.

Strengths and limitations

Strengths

• Most extensively researched BLS method with strong evidence base
• Closely matches Shapiro's original EMDR protocol
• Engages the visuospatial sketchpad, which has well-documented effects on memory reconsolidation
• No equipment required when therapist uses hand-guided movements

Limitations

• Can cause eye strain or headaches in some clients
• Difficult for clients with visual tracking issues or certain neurological conditions
• Requires in-person proximity when done with hand guidance (less suited to telehealth)
• Therapist fatigue from repetitive hand movements during long sessions

Frequently asked questions

How did Francine Shapiro discover eye movement therapy?

In 1987, Francine Shapiro noticed that her own distressing thoughts diminished while she was walking and her eyes were moving back and forth spontaneously. She systematically tested this observation, developing the structured eye movement protocol that became the foundation of EMDR therapy. Her controlled study was published in 1989 in the Journal of Traumatic Stress.

How many eye movement sets are needed in a typical EMDR session?

A typical EMDR session involves multiple sets of eye movements, with each set consisting of 20 to 30 back-and-forth cycles. The number of sets per session varies depending on the client's response, but a single desensitization phase may include 10 to 20 sets. The therapist checks in with the client between sets to assess progress.

Is eye movement therapy effective without the full EMDR protocol?

Research suggests that eye movements alone can reduce the vividness and emotionality of distressing memories, even outside the full eight-phase EMDR protocol. However, the structured EMDR framework — including preparation, assessment, and installation phases — provides a comprehensive therapeutic container that maximizes safety and effectiveness. Standalone eye movements are not a substitute for complete EMDR therapy.
