Simple to use, precise optical delivery.
Halcyon focuses on one job: delivering deep red light at a measured output, in a routine that’s easy to keep. No complicated setup. No long sessions. Just consistency.
Modern life is visually demanding
Your retina is one of the most energy hungry tissues in the body. As we age, cellular energy systems can become less efficient. Halcyon is designed as a small habit that fits real life: deep red light, delivered in a controlled session.
What if three minutes was enough?
The best routine is the one you actually keep. Halcyon is built around a short session, a simple schedule, and a calm moment in the morning.
The science, in plain terms
suggested session time
deep red light
Photobiomodulation studies how red to near infrared light (roughly 600 to 1000 nm) can interact with cellular energy processes. Research suggests these wavelengths can be absorbed by cytochrome c oxidase, a key enzyme in mitochondrial respiration, which can influence ATP production. Halcyon delivers 670 to 675 nm deep red light in a simple, timed session.
Research is ongoing. Halcyon is not a medical device and is not intended to diagnose, treat, cure, or prevent disease.
Your eyes deserve better.
