EyeLight Color Therapy
If you've struggled with focus, anxiety, insomnia, or mental fatigue, you've likely tried more than one solution already. Maybe medication helped a little, or maybe it came with side effects you didn't want to live with. At Personalizing Your Health Functional Medicine - Dr. Serle, we offer a different path: a gentle, non-invasive technology called Audio-Visual Entrainment, or AVE, that works with your brain's natural rhythms instead of overriding them.
AVE uses precisely timed pulses of light and sound to guide your brainwaves toward healthier patterns. It's simple to use, backed by decades of clinical research, and requires no needles, drugs, or downtime. For many patients, it becomes one more tool in a broader, root-cause approach to healing the Brain–Immune–Gut Connection.
What Is Audio-Visual Entrainment?
A Brainwave Entrainment Technique
Audio-Visual Entrainment is a brainwave entrainment technique. It uses gentle pulses of light, delivered through soft LED glasses, paired with rhythmic tones through headphones. Together, these light and sound pulses encourage your brain's electrical activity to synchronize with the stimulation — a process known as entrainment.
Your brain naturally shifts between different electrical states throughout the day. Some of those states support alertness and focus. Others support rest, digestion, and repair. When those states become imbalanced — whether from chronic stress, poor sleep, or a nervous system stuck in overdrive — symptoms like brain fog, anxiety, or insomnia often follow.
AVE sessions are typically short, lasting between 20 and 40 minutes. Each session uses a specific frequency pattern designed for a particular goal, whether that's calming an overactive mind or sharpening focus before a demanding task. Because the technology is precise and repeatable, it pairs naturally with the QEEG brain mapping already central to care at Personalizing Your Health Functional Medicine - Dr. Serle.

How AVE Works
Guiding the Brain's Natural Rhythms
To understand why AVE can be so effective, it helps to understand the electrical language your brain speaks. Every thought, feeling, and state of alertness corresponds to a measurable brainwave pattern. AVE is designed to speak that same language, using external rhythm to gently shift internal rhythm.
Understanding Brainwave States
Brainwave activity is generally grouped into five categories, each tied to a different mental or physical state:
| Wave | Frequency | Associated State | Clinical Relevance |
|---|---|---|---|
| Delta | 0.5–4 Hz | Deep, restorative sleep & physical recovery | Excess during waking hours may contribute to fatigue or brain fog |
| Theta | 4–8 Hz | Daydreaming, creativity & deep reflection | Plays a role in memory processing during waking and sleeping states |
| Alpha | 8–13 Hz | Calm, wakeful relaxation — "in the zone" | Supports a clear, settled mind without strain |
| Beta | 13–30 Hz | Focused, alert thinking & active problem-solving | Excess beta often linked to stress, racing thoughts, or anxiety |
| Gamma | 30+ Hz | Heightened engagement & cognitive processing | Associated with peak cognitive performance |
The Role of Light and Sound
During an AVE session, light pulses reach the eyes through LED glasses, while sound frequencies reach the brain through headphones. These pulses occur at carefully timed intervals, matched to the brainwave frequency being targeted for that session. As the stimulation continues, brain activity tends to naturally follow along.
LED Glasses
Pulsed light is delivered through soft glasses, even through closed eyelids. The visual cortex is one of the most electrically active regions of the brain — stimulating it at a precise frequency creates a powerful entrainment signal across a broad area of neural tissue.
Rhythmic Tones
Paired audio tones delivered through headphones reinforce the light signal. Because sight and sound both engage large areas of the brain, combining the two produces a stronger and more consistent entrainment effect than either modality alone.
This process can be observed on an EEG, where brainwave speed shifts in response to the rate of stimulation. Sessions are designed to begin and end gradually, easing the senses in and out so the experience feels calm rather than jarring.
AVE and the Brain–Immune–Gut Connection
No Therapy Exists in Isolation
At Personalizing Your Health Functional Medicine - Dr. Serle, every intervention is viewed through the lens of the Brain–Immune–Gut Connection — the framework Dr. Serle uses to understand how these three systems influence one another. AVE fits naturally into this model, because brainwave imbalance rarely stays contained to the brain alone.
Chronic stress and dysregulated brainwave patterns can keep the nervous system locked in a fight-or-flight state. Over time, this may affect digestion, immune function, and inflammation throughout the body. By helping calm this overactivation, AVE may support the broader systemic balance that Dr. Serle's functional approach is built around.
Brain
Dysregulated brainwave patterns drive the nervous system toward chronic fight-or-flight, disrupting focus, mood, sleep, and cognitive function. AVE helps guide brain activity back toward healthier rhythms.
Immune
Prolonged nervous system overactivation generates inflammatory signals that impair immune regulation. Calming the brain's electrical overactivity may help reduce this downstream inflammatory burden.
Gut
The autonomic nervous system governs gut motility and barrier integrity. When that system is dysregulated, digestive function suffers. AVE supports autonomic balance as part of a whole-body strategy.
This is also why AVE is rarely used as a standalone therapy. When paired with QEEG brain mapping, targeted neurofeedback, and functional medicine testing, it becomes part of a personalized picture — not a one-size-fits-all solution. Dr. Serle uses your brain map to help determine whether AVE, neurofeedback, or a combination of both fits your specific needs.
What AVE May Help Support
Areas of Clinical Relevance
Research on brainwave entrainment suggests it may offer benefits across a range of concerns, particularly those tied to an overactive stress response or disrupted brain rhythms. As with any therapy, results vary by individual, and AVE should be considered a complement to, not a replacement for, appropriate medical care.
Focus & Attention
Challenges with concentration, including patterns often associated with ADHD, may respond to frequency-specific entrainment targeting attention-related brainwave states.
Anxiety & Chronic Stress
By helping calm an overactive nervous system, AVE may reduce the physiological markers of chronic stress and the anxious thought patterns that accompany them.
Sleep Difficulties
Sessions targeting delta and theta frequencies may support healthier pre-sleep brainwave patterns, helping the nervous system transition into restorative rest more readily.
Mood Regulation
By helping the brain shift out of prolonged high-stress states, AVE may support more stable mood and emotional regulation over time.
Migraine Symptoms
Photic stimulation has been studied specifically in relation to migraine. As autonomic involvement is well documented in migraine pathophysiology, AVE may offer relevant support.
Mental Fatigue & Brain Fog
Often tied to imbalanced daytime brainwave activity, mental fatigue may improve as entrainment helps restore more appropriate electrical patterns during waking hours.
Peak Performance
For patients seeking sharper focus for academic or professional demands, AVE can be calibrated to support heightened alertness and sustained cognitive engagement.
What to Expect During an AVE Session
Simple. Comfortable. Non-Invasive.
Before Your Session
Our team will review your QEEG brain map, if available, to help select the most appropriate program for your goals. You'll get settled in a quiet, comfortable space — seated or lying down, whichever feels more natural. Most patients choose to close their eyes, since the LED glasses are designed to deliver light even through closed eyelids.
During the Session
Once the session begins, you'll notice gentle pulses of light and rhythmic tones working together. Many patients report a growing sense of calm within the first several minutes — sometimes describing it as similar to deep meditation. Your body may respond with slower breathing, warmer hands and feet, and a general sense of physical release as the nervous system settles.
After Your Session
Sessions typically last between 20 and 40 minutes. Afterward, most patients feel calm, clear-headed, and ready to return to their day. Because AVE is non-invasive, there's no recovery time needed, and many patients schedule sessions as part of an ongoing care plan rather than a one-time visit.
Is AVE Right for You?
Professional Guidance Matters
AVE is generally well tolerated, and most patients report no adverse effects. As with any brainwave-based therapy, individual sensitivity varies, and it's important to be evaluated by a qualified provider before starting.
Some patients may feel unusually sensitive to sessions, especially longer or more intense ones. If a session feels overwhelming or uncomfortable, it should be paused and discussed with your provider before continuing. At Personalizing Your Health Functional Medicine - Dr. Serle, your program is built around your unique brain map — not a one-size-fits-all setting.
Because AVE uses pulsed light, it is not recommended for individuals with a history of photosensitive epilepsy or seizure disorders, unless specifically cleared by a physician. Please disclose any relevant medical history before your first session.
