What Industry Leaders Are Saying
Got Questions? We’ve Got Answers.
Re-Timer 3 emits a specific 500nm blue-green wavelength of light that has been scientifically shown to influence the suprachiasmatic nucleus (SCN) in your brain — the master pacemaker of your circadian rhythm. When worn in the morning, this light suppresses melatonin production and signals your brain to be alert, effectively “resetting” your internal body clock to your desired schedule. The effect is similar to exposure to natural morning sunlight, but portable and consistent regardless of weather, season, or your location.
Most users report noticeable improvements within 3–5 days of consistent use. For circadian rhythm disorders and significant time zone adjustments, a full shift may take 1–2 weeks of daily 30–60 minute sessions. The companion app helps you track your progress and optimise your schedule.
Yes. Re-Timer 3 is 100% UV-free and has been designed to deliver therapeutic light without harmful radiation. The device has been developed through 25+ years of research at Flinders University and has been used safely in multiple clinical trials worldwide. However, if you have pre-existing eye conditions, we recommend consulting your ophthalmologist before use.
Re-Timer 3 is designed to be worn comfortably over most prescription glasses. The adjustable nose pads and lightweight frame ensure a secure fit. Many users successfully wear them together during their morning routine.

A full charge provides up to 7 hours of continuous use — far more than the recommended 30–60 minute daily session. Charging takes approximately 1 hour and 20 minutes via the included USB-C cable. You can easily charge it overnight and have it ready for your morning session.
