McCray FL41 Clip-on

What is the FL-41 tint? The FL-41 tint has built a strong reputation in the optical and neurology communities not through clinical trials, but through decades of consistent results and the testimonials of patients who found relief when little else worked. The rose-copper tint filters wavelengths in the blue-green light spectrum, the range most commonly linked to migraine triggers, fluorescent light sensitivity, and prolonged visual fatigue.

When should I recommend it? It is particularly well suited for patients managing chronic migraines, photophobia, blepharospasm, post-concussion sensitivity, or general light intolerance that has not responded to standard lens solutions. When a patient describes light as a trigger or a daily frustration, the FL-41 clip-on is a meaningful, low-barrier recommendation you can make with confidence.

What makes McCray different? Every clip-on is individually measured to the patient's existing frame and handmade in Canada. The fit is exact, the finish is clean, and your patient keeps the frame they already rely on. Optical practices and dispensaries across Canada work with McCray through a simple process: send us the frame, we craft the clip-on, we return it ready to dispense.
