Summary

This study tests three different types of tinted lenses—FL41 glasses, Biomedics55 contacts, and Altius grey-green contacts—to see which works best for reducing light sensitivity (photophobia) in people who get migraines or have other eye conditions. About 200 volunteers who have already used FL41 glasses will rate their light sensitivity on a scale of 1 to 10 while using each option. The goal is to find a more convenient and effective way to manage this common and disruptive symptom.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 200 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Jul 2026

An estimate. Start dates often move.

Expected to finish

Dec 2027

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Two hundred voluntary subjects will be recruited by researching those who have purchased FL-41 tinted spectacles from the Dean McGee Eye Institute Optical Department. If this does not recruit enough subjects then subject referrals will be solicited from the patient population of the Dean McGee Eye Institute and/or neurology clinics throughout the Oklahoma City metro area. Subjects must meet the following criteria in order to participate in this study: * Subjects must have worn FL-41 tinted spectacles for at least one month prior to participating in this study. * Subjects must have at least 20/30 distance visual acuity in each eye while wearing the contact lenses. Altius lenses are currently available in spherical powers from plano to -6.00. * Subjects must demonstrate the ability to insert and remove contact lenses. Assistance from friends and family is acceptable. * Subjects must not have an infectious or progressive ocular disease. Subjects not meeting all of the above criteria will be excluded from participating in this study. Early Termination: If a subject feels their photophobia increases to an intolerable level, they can stop wearing that contact lens type and switch to the other the next day or terminate participation in the study. If this occurs, the data from those subjects will still be included in the study data analysis. If a subject or physician feel that the health of their cornea is at risk, the subject will cease wearing all contact lenses and seek medical care from the Dean McGee Eye Institute. \-
