Ocular Experts Caution Against the Use of Bright Light and Blue Light Therapy Lamps

Many experts link the development of Age-related Macular Degeneration (AMD) to the cumulative lifetime exposure to blue light wavelengths, and studies indicate that a moderate increase in lifetime exposure to blue light can advance the onset of this blinding disease by several years. This has led a number of experts to caution against the use of bright and blue light therapy lamps. Sunnex Biotechnologies patented GreenLIGHT technology screens out hazardous blue light wavelengths and eliminates the risk of eye damage inherent in the use of bright light lamps and light therapy lamps that primarily emit blue light.

The consequences of AMD for users of light therapy can be severe. As reported in the journal Science on the 25th anniversary of the use of light therapy, the first person to use bright light therapy explained how light therapy became less and less effective for him over the years as his eyesight faded, and concluded "Now I can hardly see, and all hell has broken loose... I have had periods of depression lasting over a year".
