Avulux, Avulux Adapt, and Avulux Atlas are three Avulux migraine light sensitivity lens options designed for different lighting needs and preferences.

All Auvlux lenses use Avulux’s precision light-filtering approach, but they’re configured for different use cases so you can choose the best fit for your day-to-day triggers.

The base Avulux lens is intended for indoor use and overcast days outdoors.

The Avulux Adapt lens is the most well-rounded. In its deactivated state, the Avulux Adapt lens contains the same filtration properties as the base Avulux lens. When the photochromic molecules in the Adapt lens are exposed to UV outdoors, the lens darkens and filters over 90% of both harmful blue and amber light while delivering 2x better light quality than a neutral sunglass.

The Avulux Atlas lens is polarized and intended for outdoor use only. The Atlas lens delivers 2x better light quality by selectively filtering harmful light while allowing soothing light to pass. Avulux Atlas lenses are a great choice for outdoor enthusiasts and in situations with lots of reflected light (water, snow, light pavement, etc).

Avulux lenses are made using a proprietary technique that is not a tint or coating. A refined organic material is blended with proprietary dyes and resin then injection molded into a lens. The Avulux material is throughout the substrate of the lens and it’s this material that drives the filtration properties and color appearance of the lens. Since you cannot surface into the Avulux material (this will change the filtration properties), semi-finished lenses are made with an Avulux filtration layer on the front side fused with a clear layer on the back.

Our manufacturing process subjects the lens to high heat and polycarbonate is the most durable material for these processes.

The Avulux lens is design-agnostic and compatible with any full backside, free-blank designs. It is up to our lab partners to choose the lens designs offered alongside Avulux lenses.

It is always recommended to use a fully rimmed frame with Avulux lenses. It is not recommended to drill into the lenses, so we recommend against rimless and semi-rimless frames. Some labs may still process jobs with rimless and semi-rimless frames, it depends on their level of comfort doing so. It is important to use an eye size that provides the wearer sufficient coverage, as the purpose of the lens is to prevent harmful light from entering the wearer’s eyes.

In some ways, FL-41 was a very early precursor to Avulux; but Avulux is much more advanced. FL-41 refers to a way of dyeing/tinting a lens that was originally developed in the 1980s as an early “blue blocker” to combat fluorescent light sensitivity (that’s what the FL stands for). While FL-41 does indeed block a portion of blue light, Avulux very precisely blocks blue, amber and red light waves that have been shown in various scientific studies to trigger and exacerbate migraine attacks. Importantly, Avulux allows soothing green light through, as this green light has been shown to have a soothing effect in these same studies. Avulux overall delivers 2x better light quality when compared to FL-41 lenses, meaning more soothing light passes through all while blocking even more of the harmful light.

Avulux lenses should only be cleaned with mild soap and cold to lukewarm water. We recommend against using lens cleaners as some may contain harsh chemicals that could negatively impact Avulux lenses.

Avulux lenses are not recommended for driving at night. Avulux lenses pass the traffic light test, meaning they don't distort the color perception required to properly assess traffic light color.

Patients may confirm they're comfortable wearing Avulux for driving by first wearing them as a vehicle passenger.

All Avulux lenses come with factory hardcoat. Anti-reflective coatings are recommended and come standard on Avulux plano lenses.

Blue light coatings aren't necessary since the Avulux lens already filters more blue light than a typical blue light coating.

There is only one Avulux lens density and this is due to the precise transmission curve of the lens. The lens is not currently available with a photochromic tint, or in an outdoor sun lens.
