25 years university research

Re-Timer is University developed and scientifically proven to re-time your body clock. Since 1987, world-renowned sleep psychologists at Flinders University have studied the effects of light on the human body clock. Eleven patents and studies are evidence of the performance of the Re-Timer technology. Read our research here.

Superior green-blue light

The green-blue color has been chosen for both safety and efficacy. Green-blue light is most effective at re-timing your body clock.

100% UV-free

Re-Timer light is UV-free and has been independently tested for eye safety to the international standard CEI IEC 62471.

Just 30 minutes a day

Re-Timer is worn while you are awake either in the morning or evening, depending on how you wish to change your sleep. A recommended schedule to change your sleep is typically 7 days for 30 minutes each day. To beat Long Winters, Re-Timer can be worn daily throughout winter or just used on the darker colder days when you wish to boost your energy and mood.


Optimal Delivery Angle

Most light entering the eye is from below. Re-Timer replicates this. If light were delivered from above it would be blocked by your eyebrows, diminishing performance.

Sleep clinic recommended

Sleep clinics around the world recommend Re-Timer.

“I see many people with body clock problems which can be readily managed with light therapy. Their ease of use and portability make them an excellent option…” Dr. Marcus McMahon.

Portable & rechargeable

At just 2.64 ounces (75 grams), Re-Timer is the weight of sunglasses.
Watch TV, eat breakfast or read the newspaper as you use Re-Timer. Re-Timer has an in-built battery which is recharged via a USB cable.

A better night’s sleep, naturally
