The science
The research is established.
The product is being validated.
This page separates published circadian research from OptimRise development targets and preliminary engineering measurements.
How to read this page
Two kinds of evidence,
kept apart.
General circadian science
Peer-reviewed research about light, the eye and circadian timing. Externally citable, and every claim below links to its primary source. It describes the field OptimRise is built on — not OptimRise's own results.
OptimRise-specific
The production design is targeting a spectrum near 480 nm. One preliminary engineering-validation reading peaked near 472 nm. The target and preliminary result remain separate until production-intent spectrum and eye-level output are validated.
In plain terms
Six things worth understanding.
How the eye senses light
Specialized retinal cells containing melanopsin, together with input from rods and cones, help translate light exposure into signals involved in circadian timing.
This is why light is a biological input and not only a visual one, and it is the mechanism every product in this category depends on.

Timing changes what light does
The same light has different effects depending on when it lands. Light in the morning tends to shift circadian timing earlier; light in the evening and at night shifts it later. This relationship is mapped in what researchers call a phase response curve.
That is the reason OptimRise is a morning product rather than an all-day one.

Why we are aiming near 480 nm
Human melanopsin sensitivity is commonly reported near 480 nm. Studies of sustained human circadian responses have identified peaks around 477–483 nm under specific experimental conditions. The CIE melanopic weighting function peaks nearer 490 nm; these values describe different measurement models and conditions, not competing product scores.
OptimRise V1 is targeting a production spectrum near 480 nm. Early EVT testing measured a spectral peak near 472 nm. Final evaluation requires the complete measured spectrum, eye-level output, exposure geometry, intended duration and photobiological safety testing.
Wavelength is one part of the design, not a complete biological dose or safety claim.

What we measure, and what we have not measured
Because the relevant receptors are inside the eye, product output should be measured at the eye on production-intent hardware. That validation is not complete, so OptimRise is not publishing an eye-level output or melanopic EDI figure yet.
We will publish verified measurements rather than use an unmeasured “equivalent to 10,000 lux” comparison.

Twenty minutes is a design decision
Twenty minutes is the intended bounded V1 setting and remains subject to final validation. It is a product decision, not a promise of a specific health outcome.
Responses to light vary with spectrum, intensity, timing, duration, prior exposure and the individual. No fixed session produces the same response in everyone.

Safety: what we can say, and what we can't
Product-specific photobiological safety validation is underway and must be completed before shipment. When production-intent testing is complete, OptimRise will publish the applicable report reference.
If you have an eye condition, take a medication that increases light sensitivity, or have a condition affected by bright light such as bipolar disorder, consult a qualified healthcare professional before using any bright-light product.

Being explicit
Four things to know
while we validate V1.
- Consumer wellness product in developmentOptimRise is not intended to diagnose, treat, cure or prevent disease and is not FDA-approved or FDA-cleared.
- Production validation is still aheadThe hardware shown is an engineering-validation unit. Production-intent optical output and photobiological safety testing must be completed before shipment.
- Targets and measurements stay separateV1 is targeting a production spectrum near 480 nm; one preliminary EVT reading peaked near 472 nm. Neither is presented as a tested product outcome.
- Individual precautions matterPeople with eye conditions, medications that increase light sensitivity, or conditions affected by bright light should consult a qualified healthcare professional before use.
Clear about what is established. Equally clear about what remains to be validated.
