Light Therapy and Eye Safety

Can Bright Light Therapy Damage the Eye?

Experts are concerned that blue light wavelengths emitted from bright light therapy lamps contribute to the development of age related blindness. Refs. It is recommended users of blue or bright light therapy lamps be screened by ophthalmologists, and those with pre-existing retinal conditions not use bright light therapy treatment or be closely monitored. Refs.

The low intensity GreenLIGHT technology used in Lo-LIGHT therapy lamps eliminates the risk of retinal damage from bright light or blue light therapy lamps. Lo-LIGHT lamps operate at normal indoor light intensity and do not emit the hazardous blue wavelengths of light that damage the retina.

People using bright light or blue light therapy while taking photosensitizing medications have an increased risk of eye damage. Medications that sensitize the eye to damage by blue light include nonsteroidal anti-inflammatory drugs (NSAIDs), antidepressants, antibiotics, diuretics, beta-blockers and other heart medications. Refs.

Impaired vision can be particularly difficult for people suffering from depression. Herbert Kern, the first person to use bright light therapy, described in the journal Science how light therapy became less and less effective for him over the years as his eyesight faded because of his developing AMD. He explained, "Now I can hardly see, and all hell has broken loose" "I have had periods of depression lasting over a year..."
