Understand How Arizona State University Uses Green-Enriched Light for Migraine Relief
For the roughly one billion people worldwide who suffer from migraines, light sensitivity—clinically known as photophobia—is one of the most debilitating symptoms. The standard advice for decades has been to retreat to a dark, quiet room when an attack hits. However, isolating oneself in darkness carries significant negative side effects, including disrupted sleep cycles, increased stress, and impaired cognitive function. Researchers at Arizona State University have challenged this outdated paradigm by developing an innovative approach to lighting technology that provides measurable migraine relief without forcing patients to live in the dark.
By engineering a specific type of green-enriched light, ASU researchers have created a practical, real-world solution that allows individuals with migraine disorders to remain active in well-lit environments.

The Problem with Traditional Lighting for Migraine Sufferers
Modern indoor environments are predominantly illuminated by light-emitting diodes (LEDs). To enhance alertness and energy efficiency, many of these commercial and residential lighting systems are engineered to emit blue-enriched or cyan-enriched white light. While this lighting technology is heavily marketed as beneficial for productivity and circadian rhythm regulation, it presents a severe problem for people living with neurological conditions.
For a migraine patient, exposure to blue and cyan wavelengths can trigger or exacerbate an attack, significantly worsening visual discomfort. Nina Sharp, an associate professor in The Design School at Arizona State University, understands this dynamic firsthand. Having experienced migraines since the age of five, Sharp has frequently had to teach her university classes in near-darkness to manage her symptoms. She recognized that the prevailing approach to “healthy lighting” in the USA was fundamentally flawed for a massive segment of the population.
Spending extended periods in darkness is not a sustainable treatment strategy. The lack of proper light exposure negatively impacts mood, exacerbates anxiety, and deteriorates overall cognitive performance. Finding a way to maintain functional, well-lit spaces without triggering neurological pain became the primary focus of Sharp’s research.
The Science Behind Green-Enriched Light
Prior studies had established that pure green light could reduce pain signals in migraine patients. However, translating that clinical finding into a viable lighting technology presented a massive logistical hurdle. Installing bright green bulbs in homes, hospitals, schools, and offices across the USA is highly impractical. Furthermore, prolonged exposure to monochromatic colored light can induce brain fatigue, even in individuals without migraine disorders.
Why Pure Green Light Isn’t Practical
A household or workplace cannot function effectively under an overlay of green light. Colors appear distorted, and the environment feels unnatural. Sharp needed to formulate a lighting solution that would provide the neurological benefits of green wavelengths while maintaining the standard, high-quality white illumination required for daily tasks.
The breakthrough came through the development of green-enriched white light. By carefully calibrating the spectrum of standard white light to include a higher proportion of green wavelengths—while minimizing the harsh blue and cyan frequencies—the researchers created a light source that looks virtually identical to regular indoor lighting. To the naked eye, this green-enriched light appears slightly warmer than standard LEDs, but it remains entirely functional for reading, working, and navigating a space.
Clinical Trials and Measurable Results
To validate this lighting technology, Sharp partnered with Dr. Todd Schwedt, a neurologist and headache specialist at the Mayo Clinic. Together, they designed a rigorous study to test four distinct types of white light: blue-enriched, cyan-enriched, red-enriched, and green-enriched.
The study participants, all of whom suffer from migraine disorders, were asked to visit the testing facility twice—once while experiencing an active, untreated migraine attack, and once while symptom-free. During these sessions, they were exposed to each of the four lighting conditions at varying intensities for ten-minute intervals, with their visual discomfort measured every minute.
The results clearly demonstrated the advantages of the green-enriched light:
- Blue and Cyan Light: These wavelengths significantly worsened visual discomfort. Participants frequently asked researchers to turn the lights off entirely, unable to tolerate even low intensities.
- Red-Enriched Light: This performed better than blue and cyan but was still inferior to the green-enriched option.
- Green-Enriched Light: This condition actively relieved visual discomfort and slightly reduced the overall intensity of the patients’ headaches.
Remarkably, the control group—participants without migraine disorders—also reported that the green-enriched white light was more visually comfortable. Furthermore, cognitive testing administered during the study showed that both groups performed better under the green-enriched lighting.

Bringing Lighting Technology from the Lab to the Clinic
Scientific data is only valuable if it can be translated into practical applications. Following the clinical trials, Sharp and Schwedt spent years fine-tuning the precise balance of light waves required to optimize the migraine relief benefits. This iterative process led to the founding of a startup focused on manufacturing “neuro-optimized” lights for consumer and commercial use.
The first real-world deployment of this lighting technology occurred at the Dr. Bondy Headache Center in Fountain Hills, Arizona. Dr. Brooklynn Bondy, a neurologist and headache specialist who also lives with migraines, intentionally designed her clinic to minimize patient triggers. Photophobia is one of the most common complaints among her patients, making the lighting selection a critical component of their care.
Dr. Bondy installed the neuro-optimized, green-enriched lighting system in her treatment rooms, specifically where she performs delicate procedures like nerve blockers. In the past, she had to compromise between having enough light to see the injection site accurately and keeping the patient comfortable. The green-enriched white light eliminated this compromise, providing excellent visibility for the physician while preventing the light from triggering or worsening the patient’s pain.

Broadening the Impact of Migraine Relief in the USA
The implications of this research extend far beyond a single medical clinic. As awareness of photophobia and neurological wellness grows, there is a pressing need to rethink how indoor spaces are illuminated across the USA. Current architectural and interior design standards often prioritize energy efficiency and aesthetic brightness over neurological health.
Sharp’s mission is to shift this paradigm. By demonstrating that blue-enriched white light can be actively harmful to a significant portion of the population, she is challenging the lighting industry to adopt more inclusive standards. Implementing green-enriched lighting technology in corporate offices could reduce the number of migraine attacks triggered by harsh overhead lights, potentially lowering absenteeism and increasing productivity. Similarly, schools that adopt this technology could create more accommodating environments for students who currently suffer in silence under fluorescent or standard LED fixtures.
For individuals managing migraine disorders, this research offers a clear, actionable takeaway: audit your personal environment. While widespread commercial adoption of neuro-optimized lighting is still in its early stages, understanding the impact of blue light versus green light can help you make better choices for your home office or bedroom. Opting for warmer, green-enriched light bulbs can serve as a proactive step to reduce your daily exposure to triggering wavelengths.
Next Steps for Managing Light Sensitivity
The development of green-enriched light represents a significant step forward in non-pharmacological migraine management. It proves that environmental design can directly influence neurological pain and that practical solutions do exist to help patients stay out of the dark. As this lighting technology becomes more widely available, it has the potential to drastically improve the daily lives of millions of people.
If you or a family member experience severe light sensitivity, consider evaluating the lighting sources in your most frequently used spaces. Transitioning away from high-intensity, blue-enriched LEDs can be a simple but effective adjustment.
