PHOTOBIOLOGY AND CIRCADIAN LIGHT SCIENCE

Photobiology, Circadian Light Science & Ophthalmic Lens IP

Acieon Labs is the research and intellectual property division of Sleepaxa Private Limited. It studies how biologically relevant wavelengths interact with retinal light-signalling pathways, including melanopsin and intrinsically photosensitive retinal ganglion cells, to guide wavelength-selective ophthalmic lens technologies.

Acieon Labs is a photobiology research division based in India. It develops and holds the intellectual property behind wavelength-selective ophthalmic lenses. Its work characterises how specific wavelengths of light drive melanopsin phototransduction in intrinsically photosensitive retinal ganglion cells, and how selective spectral filtration can preserve beneficial daytime light while attenuating the evening wavelengths that suppress melatonin and delay circadian phase.

What is Acieon Labs

Acieon Labs is a photobiology research and intellectual property division. We translate non-visual photoreception biology into research-led optical filtration frameworks. Our work begins at the photon and ends at the suprachiasmatic nucleus. We characterise how specific wavelengths drive melanopsin phototransduction in intrinsically photosensitive retinal ganglion cells, and we engineer spectral filters that preserve beneficial daytime light while attenuating the evening wavelengths that suppress melatonin and delay circadian phase.

Acieon vs Sleepaxa

A clear separation of research and commerce

Acieon Labs

Research, IP, publications, patents, ethics, evidence, and clinical and scientific documentation.

Sleepaxa

Commercial eyewear products, consultation, customer support, order processing, and fulfilment.

The principle

Every photon works for the human eye.

Every photon that enters the eye carries spectral information. Some photons support vision and daytime alertness. Others, concentrated near the melanopic action spectrum, reach the circadian system at the wrong hour. The Acieon Labs principle is that filtration should be selective rather than blunt, so that every photon works for the human eye rather than against it.

The science

Light is a spectrum, and the eye reads it

Across the 380 to 720 nm extended visible-to-near-red research window, the melanopsin response peaks near 480 nm. Acieon Labs studies how selective filtration shapes the light that reaches the circadian system.
