E-15 Blue

Large-scale anecdotal evidence based on Chadwick’s experience tinting 10,000s of E blue shades suggests these tints are highly suited for relief from migraine, concussion, brain injury symptoms. We’ve found E blues to be especially popular with Veteran Affair TBI centers and have worked closely with VA doctors to confirm their efficacy in minimizing patient symptoms.

Z Blue

Also known as z1 Blue or NoIR 26, this highly specialized lens suppresses the brain activity triggered by flickering or intense light in highly photosensitive patients. By filtering the specific wavelengths known to trigger seuizures, it provides a vital layer of protection for patients with epilepsy. A 2006 Italian study found that the Z Blue lens effectively controlled symptoms in over 93% of participants.

NoIR 88

Spectrographically matched to Axon’s FL-41 filters, NoIR 88 is a soft plum tint designed to block the harsh blue-green wavelengths emitted by fluorescent lights and digital screens. It is ideal for continuous indoor use, providing relief from mild glare and screen-induced eye strain without overly darkening the wearer's vision.

NoIR 81

Tailored for pronounced sensitivity to artificial lighting, this plum lens matches the protective profile of Axon’s FL-41 filters with a slightly deeper tint. It effectively reduces painful glare from overhead commercial lighting in places like supermarkets and offices to help prevent migraine onset and ease chronic photophobia.

COI Plum

Serving as a versatile middle-ground, this moderate plum shade strictly adheres to FL-41 standards to combat severe light sensitivity in mixed-use environments. It provides a robust shield against both natural and artificial glare, making it highly effective for individuals suffering from chronic migraines or post-concussion syndrome.
