Silent Light is listed as an ARTG Class I medical device.

How does Silent Light work?

Silent Light is a wearable wellness device that emits low-intensity red light at the skin surface. Light-based technologies of this kind, broadly known as photobiomodulation, have attracted significant scientific interest over recent decades. Silent Light is intended for general wellness use — designed to be a calm, comfortable part of your evening routine.

Is Silent Light a treatment for sleep apnoea?

No. Silent Light is not intended to diagnose, treat, cure, or prevent sleep apnoea or any other medical condition. Individuals diagnosed with obstructive sleep apnoea should follow the advice of their healthcare professional. If you use CPAP or another prescribed therapy, consult your healthcare provider before using Silent Light.

Can I use Silent Light with CPAP?

Silent Light may be used alongside CPAP therapy; however, it is not a replacement for prescribed treatment. If you have been diagnosed with sleep apnoea, you should speak with your healthcare professional before combining therapies.

Is Silent Light safe?

Silent Light is a non-invasive wearable device designed for external use only. It does not penetrate the body, does not emit heat at harmful levels, and does not deliver electrical stimulation. As with any wearable device, discontinue use if skin irritation occurs and consult a healthcare professional if you have concerns.

Who is Silent Light suitable for?

Silent Light is designed for adults seeking support for nighttime Snoring, comfort and quieter sleep environments.
It is not intended for:

Does Silent Light replace mouth guards or nasal strips?

Silent Light works differently from mechanical devices such as mouth guards or nasal strips. It is designed to support the body's natural function rather than repositioning the jaw or altering airflow
mechanically. Some users choose to combine different approaches. Always consult a healthcare professional if
unsure.
