A new world
of photobiology.
The science of how specific wavelengths of light shape the human brain — sleep, pain, mood, alertness, memory. We engineer the optical filters that translate this science into clinical relief.

Eyewear, reframed as medicine for the photic system.
For a hundred years, glasses have done one thing: bend light to the retina. We work in the second register — which wavelengths reach the brain. By selectively attenuating the bands that drive migraine, suppress melatonin, or destabilise the circadian clock, while preserving the bands the visual system needs, we are designing a generation of lenses that are clinical instruments first and accessories second.
Four lines of active inquiry.
Each stream is grounded in published photobiology and validated against in-house spectral measurement. None of this is marketing.
ipRGC & melanopsin signalling
Intrinsically photosensitive retinal ganglion cells regulate circadian timing, melatonin synthesis, pupillary response, and a documented migraine pain pathway. Our work characterises subtype-specific wavelength sensitivity and translates it into lens specifications.
Dual-band selective attenuation
FL-41 evolved. Granted Indian Patent IN 587746 describes a dual-notch lens addressing both the 460–490 nm melanopsin pathway and the 585–600 nm cone-driven pathway identified by Noseda et al. (Brain, 2016) — while preserving the 520–560 nm green band shown to reduce migraine severity.
Sub-560 nm cutoff lenses
A complete short-wavelength cutoff for the post-sunset window, engineered to maximise melanopic protection without the perceptual penalty of conventional amber lenses. The technology is the subject of pending application IN 202521120977.
Portable spectral measurement
Most clinical environments cannot quantify the light their patients are actually exposed to. We are building VYLO — a portable, sub-second photobiological light scanner reporting CIE S026 melanopic EDI, CCT, flicker, and circadian-stress metrics in real time.
