FAQ
How are Avulux lenses made?
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.
Why are Avulux lenses polycarbonate only?
Our manufacturing process subjects the lens to high heat and polycarbonate is the most durable material for these processes.
What lens designs are available for Avulux lenses?
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.
What frame types are recommended for 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.
How are Avulux lenses different from FL-41?
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.
How do you clean Avulux lenses?
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.
Can you drive with Avulux lenses?
Avulux lenses are not recommended for driving per ISO 12312-1:2013. This is not due to the overall filtration being too dark (the filtration is only about 45%), or the distortion of traffic light color. These ISO standards were written for typical ophthalmic lenses rather than precision optical filters like the Avulux lens. At a certain wavelength (590nm), Avulux lenses filter out about 97% of light and this falls below the ISO standard to be recommended for driving.
What base curves are available?
Plano: 2,4,6,8
Semi-finished: 2,4,6,8
Chemistrie Avulux: 4
What coatings are recommended for Avulux lenses?
All Avulux lenses come with factory hardcoat. Anti-reflective coatings are recommended for Avulux lenses. Blue light coating is not necessary since the Avulux lens already filters more blue light than a typical blue light coating.
Is there more than one Avulux density?
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.
