Study summary

The purpose of this study is to determine if a special coating, applied to the surface of glasses can reduce the frequency and severity of migraine headaches in children and adolescents. This study is being conducted by researchers at Primary Children's Medical Center, The John Moran Eye Center, and the University of Utah Department of Electrical Engineering. The investigators have determined that a specific frequency of light is particularly bothersome to migraine patients. The coating they've developed is designed to block this frequency of light. Very few treatments are approved for the treatment of childhood migraine. The investigators hope that these glasses will provide a safe way to improve headaches in children.

What researchers measure

Primary outcomes

  1. HIT-6 Score

    The HIT-6 (Headache Impact Test) is a validated measure of the impact of headache on activities of daily living, functional health and well-being. The minimum score is 36 and the maximum score is 78. The higher the score, the more your headaches are adversely affecting activities of daily living. Patients who score higher than 50 are encouraged to seek help from their physician.

    Time frame: 12 weeks

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jan 2014, a primary completion of Apr 2018 and a completion of Apr 2018. It does not say whether these dates are actual or estimated.

Results were first posted in Mar 2020, 1 year 11 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 9, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
