FL-41 Light Sensitivity Clips

An FL-41 tinted lens that clicks onto the glasses you already wear.

FL-41 is a rose-colored tint used for light sensitivity. It filters part of the blue-green range that many light-sensitive people find hardest to be around, especially under fluorescent and LED lighting, without darkening everything the way sunglasses do.

Two intensities, Light and Medium. Both custom-made for your frame.

Yes, that's how most orders work. You order the clip, we send a prepaid label, and you mail us the glasses you already wear. Our lab sets discreet magnets into your lenses, cuts the clip edge to edge to match your lens shape, and sends both back together.

The magnets become part of your lenses, which is what lets the clip line up perfectly every time. Your frames look exactly the same, and once your glasses are clip-ready you can add other Chemistrie clips to the same pair. If a clip isn't right for you, return it within 30 days and we'll fit new lenses in your original prescription type.

We work with virtually any frames, including full-rim, semi-rimless, and rimless.

Please note: we don't modify safety eyewear, since drilling would affect its impact rating, and we don't drill glass lenses.

Light (20%) for mild sensitivity. Medium (50%) for more pronounced sensitivity.

Both are custom-made for your frame and both use the same FL-41 tint. What changes is how much of it.

You can order both for the same frame if you want one for work and one for harder days.

There's a rose cast, yes. How strong depends on which tint you pick.

Light (20%) is the subtler of the two. Medium (50%) is visibly rose, both to you and to other people.

Whites will read warm either way. Color-critical work is easier with the clip off.

Different lens for a different problem. Neither is a step up from the other.

FL-41 is a broad rose tint, used for years by people who struggle with fluorescent lighting, bright rooms, and long screen days. It's comfortable to wear for hours and comes in two intensities so you can dial it in.

Chemistrie Migraine Clips uses Avulux, a precision multi-band filter with its own clinical testing behind it, made specifically for people living with migraine.

If it's everyday light that wears you down, start here. If migraine is the reason you're looking, look at Chemistrie Migraine.

Yes. Those are exactly the environments it's designed for: offices, classrooms, stores.

Fluorescent tubes and some LED panels throw a lot of short-wavelength light, which is what many light-sensitive people find hardest. FL-41 filters part of that band without making the room dark, so you can still read a screen and see faces.

It clicks on at your desk and off when you leave.

That depends on which tint you chose.

Light (20%) is made for indoor light. Medium (50%) is intended for indoors and outdoors, so if you want one clip that goes from the office to the parking lot, Medium is the one to pick.

For bright sun specifically, plenty of people add a Sun clip to the same frame and swap between the two.
