Traditional light therapy devices use white light. Blue light is more energetic than white light, which has raised concern with ophthalmologists because blue light can damage the retina and increase the risk for macular degeneration.

Macular degeneration is the degeneration of key areas of the retina which is what allows us to actually see things. The people most at risk for macular degeneration include:

  • People over 55 years old
  • People who have genetic risk (a family member with macular degeneration)
  • People with diabetes

Studies suggest that the visible blue light wavelengths emitted by blue light therapy lamps make the risk of retinal damage even greater for those with pre-existing retinal conditions, those using photosensitizing medications or supplements and older people.

The term “blue light hazard” is used to describe about 90% of the risk of photochemical retinal damage from fluorescent blue light lamps. Blue light is absorbed by retinal tissue which induces oxidative stress and can cause the formation of indigestible debris which can accumulate in the outer retina. This can contribute to the development of macular degeneration.

If you have an eye condition, eye disease or think you may be at more risk for developing macular degeneration, you should definitely avoid blue light. You should also consult your ophthalmologist for guidance if you have a history of eye disease or light sensitivity.

Say NO to Red Light Therapy

Red light therapy is associated with the treatment of skin disorders and is characterized by infrared light which is directed at the skin. It is used to reduce the appearance of fine lines and wrinkles, sun damage and treat skin problems like acne, eczema, jaundice or other skin disorders.

“My vitamin D was very low. My doctors wanted me to get out in the sun more and take additional D supplements. Being in the wintertime, sun is sometimes hard to find and when it is out it is usually very gold - not my kind of walking or sitting out in weather. This machine gives me the dose of vitamin D I need daily in only 5 minutes a day. It really helps raise my spirits as well. Good bye cold walks and damaging sun on my skin. This machine replaces what I need without the damage.”
