Trial Title: Spectacle Tints and Thin-Films for Migraine

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Subjects must meet the International Headache Society criteria for chronic migraine (International Classification of Headache Disorders, 3rd edition (Headache Classification Committee of the International Headache Society, 2013). All subjects must be between the ages of 18 and 60 years-old.~To be included in the study, in the best judgment of the investigator, subjects must be stable on their current migraine treatment regimen. Stability is defined as no major changes in therapy contemplated within the next 4 months.~Exclusion Criteria:~* Subjects with other light sensitive conditions, such as iritis and blepharospasm, will be excluded. Subjects with best-corrected visual acuity less than 20/40 will be excluded. Subjects with diseases of the retina, such as diabetic retinopathy and macular degeneration will be excluded. Subjects using medications known to affect the eye will be excluded (e.g. chloroquine, hydroxychloroquine, ethambutol, amiodarone). Due to constraints on the manufacture and mounting of study lenses into study frames, the study must exclude subjects who are very nearsighted (more than 4 diopters), subjects who are very farsighted (more than 2 diopters), and subjects who have more than 2.5 diopters of astigmatism.~Because of the cyclical effects of botulinum toxin injections and other nerve blocks, patients undergoing these treatments will be excluded. Subjects must not have had any injections or blocks within 4 months of enrollment and should not receive any further blocks until they exit the study.~Subjects with continuous daily headache (a headache frequency of 100%) will be excluded. Subjects who do not have a headache frequency of at least 50% will be excluded.~Subjects with medication overuse headache will be excluded. A patient with a history of medication overuse who has not overused abortive medications for the past 4 months can be included.~Subjects who abuse alcohol or use illicit drugs will be excluded. Subjects considered to be from vulnerable populations will be excluded, including pregnant women, prisoners, subject who are mentally disabled, subjects with cognitive or decisional impairment, and wards of the state

Study Arms:
- Gray tinted spectacle lenses (Type: ACTIVE_COMPARATOR): Subjects in this arm will be asked to wear a neutral gray tint that blocks all wavelengths equally
- Thin-Film spectacle lenses (Type: EXPERIMENTAL): Subjects in this arm well be asked to wear a thin-film coating that specifically blocks 480-nm wavelength

Based on this trial design, predict the completion outcome and termination type (if applicable).
