Almost nothing is asked of you.

No. AOI is an experiential wellness and lifestyle technology. It is not a medical device, it is not intended to diagnose, treat, cure, mitigate or prevent any disease, and it does not replace appropriate medical or psychological care. CE certification is ongoing.

Do not use AOI if you have photosensitive epilepsy or a history of seizures triggered by light, or if flashing, flickering, dynamic or high-contrast visual stimulation is known to cause you significant symptoms. Do not begin a session during migraine aura, severe headache, acute dizziness, nausea or disorientation; during an active panic attack, or where severe claustrophobia makes safe use inappropriate; while alcohol, recreational drugs or medication significantly impair your perception, balance or reaction time; or whenever your physical or mental condition makes intensive sensory stimulation inappropriate.

AOI is not recommended for unsupervised use by anyone with a diagnosed psychiatric disorder unless the condition is stable and use has been discussed with their treating psychiatrist. It must not be used during an acute psychiatric state, including active psychosis, mania, severe dissociation, severe agitation or confusion, significant suicidal or self-harm risk, or any condition significantly affecting perception, judgement or the ability to use the chamber safely.

Seek appropriate professional advice before your session if you are pregnant, have a neurological disease, have significant eye disease or recent eye surgery, take photosensitising medication, have an implanted or electronic medical device, or live with an unstable cardiovascular condition. The available AOI documentation does not establish universal protocols for these situations — when in doubt, speak to your physician or treating specialist first.

Arrive adequately hydrated; normal hydration is enough and excessive water is not required. Avoid a large or heavy meal immediately beforehand. Check how you feel on the day, and do not begin if you are significantly dizzy, nauseous, disoriented, acutely unwell, or in the middle of a migraine aura or severe headache. Do not come intoxicated or otherwise impaired.

It is your choice. Closed is advised, and especially so if your eyes are sensitive — an opaque eye mask or blackout goggles is provided and worn where the program calls for it. Never deliberately look into individual LEDs at close range: the manufacturer's instructions warn that direct close-range LED viewing may cause eye irritation or injury.

Do not rush out of the chamber. Give yourself a moment to reorient, and make sure you feel awake, know where you are, can stand comfortably and can walk normally. We recommend resting for at least ten minutes somewhere dark and quiet, and drinking water according to your normal needs. If a session leaves you emotionally heightened, unusually sensitive or irritable, give yourself extra time before driving or making important decisions.

As often as suits you. There is no required cadence for a studio session — come when it fits your week, and let your own experience set the rhythm. It is worth noticing which time of day works for you: a session close to bedtime can feel stimulating, so leave more time before sleep, and allow about an hour afterwards if you are using one before something that matters. Chamber owners follow a structured journey instead, described on the Method page.
