Light Therapy without the risk of eye damage

Light Therapy that's Safe, Comfortable, and Effective

The Superior Light Therapy Lamp
For Seasonal Depression

The Lo- LIGHT therapy lamp provides low intensity light therapy for sleep and mood disorders including Seasonal Affective Disorder (SAD or Winter Depression). Since 1995, the patented technology used in this low-intensity light therapy lamp has provided the benefits of light therapy safely and comfortably, without the risk of eye damage that other light therapy lamps may cause.

It's Worth It To Protect Your Vision

Age-Related Macular Degeneration (AMD) is reaching epidemic proportions in the developed world. Experts have linked the development of AMD with the retinal stress that results from the absorption of visible blue light in the retina. Oxidative damage caused by the "blue light hazard" accumulates in the retina throughout life. Recent research indicates that regularly subjecting the eye to increased levels of exposure to blue light wavelengths, even in young adults, advances the onset of this debilitating disease later in life by several years. Older people are at greater risk because the retina becomes increasingly vulnerable to photo-oxidative stress from blue light after age forty. Regular exposure to light therapy devices that emit high intensity "bright" light, or light with a high proportion of blue light wavelengths can only advance the onset of AMD in users of this manner of light therapy. Sunnex Biotechnologies patented Lo-LIGHT technology screens out the hazardous blue light wavelengths and provides a safe alternative that poses no increased risk of eye damage.

The consequences of AMD for users of light therapy can be severe. It is worth noting what Herbert Kern, the first person to use bright light therapy for the treatment of Seasonal Affective Disorder (SAD), said in the Sept 14, 2007 issue of Science regarding his developing AMD. After explaining that [bright] light therapy became less and less effective for him over the years as his eyesight faded, he said "Now I can hardly see, and all hell has broken loose" "I have had periods of depression lasting over a year...".

Tested and Validated in Laboratories Around the World

An independent study by the Canadian Defense Research and Development Centre and the U.S. Air Force recently confirmed that Sunnex Biotechnologies low intensity green light therapy technology provides the most efficient form of light therapy. This study found that less than 10% of the intensity (energy) of light from a GreenLIGHT lamp induces double the physiological response as The Litebook®, a therapy device that primarily emits blue visible light wavelengths. (More at Studies in the Workplace).

The U.S. Coast Guard developed the light management protocol for their Crew Endurance Management System (CEMS) using GreenLIGHT lamps. Years of trials at the USCG R&D Center has shown that the low intensity GreenLIGHT lamps are an equivalent alternative to "bright light" for light management of circadian rhythms. This fatigue management program now being implemented on commercial vessels in the US and Europe. (See Using the GreenLIGHT System for counteracting night work fatigue)

Sunnex Biotechnologies low-intensity light therapy lamps are currently in trials at a U.S. Naval Medical Center to help correct sleep disorders of veterans with head injuries, and by the U.S. Air Force and the Canadian Defense Research and Development Center for maintaining operational alertness at night.

For Non-Seasonal Major and Bipolar Depression

In addition to the numerous people successfully using Lo-LIGHT therapy for Seasonal Affective Disorder (SAD) and sleep disorders, Lo-LIGHT therapy lamps have shown dramatic benefits when used in combination with antidepressant medications for non-seasonal Major Depression. Studies published in the most prestigious psychiatric journals have also found properly timed exposure to this low-intensity green light therapy provides rapid and sustained relief of Bipolar Depression, without the use of antidepressants or anti-psychotics. Because of the demonstrated efficacy and lack of adverse side effects, this chronotherapeutic intervention is now being recommended as a first line intervention for bipolar depression in clinical practice.
