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 (circadian rhythm). Eleven patents and five clinical trials are evidence of the performance of the Re-Timer light therapy technology. Read our research here.


“Re-Timer works. It took less than a week to dramatically transform the time I went to sleep and the time I got up. All I had to do was wear Re-Timer once a day for less than an hour and boom my sleeping pattern was changed. It was easy. Probably too easy. Highly recommended.”

100% UV-free

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

Superior green-blue light

The green-blue color has been chosen for both safety and efficacy. Green-blue light therapy is most effective at re-timing your body clock (and suppressing melatonin, the hormone our bodies produce which makes us feel sleepy).

Sleep clinic recommended

Sleep clinics around the world recommend Re-Timer.

“As a Sleep Disorders Physician, I see many patients with body clock problems which can be readily managed with light therapy. Their ease of use and portability make them an excellent option for treating circadian rhythm disorders.” 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.

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 treat Seasonal Affective Disorder, 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.


A better night’s sleep, drug free

Sleep medication may not treat the underlying problem. This is why so many people on medication complain of insomnia.
Re-Timer uses light therapy, a natural solution.

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.
