Sickle Cell and Blue Light Jack Kruse MD

Several of my members recently went to a bio-hacking conference in California and were told blue light exposure during the day was NOT harmful, and quite helpful for the human eye. I've decided to share a few things with you over the next few weeks that challenges this very bad idea. People have no idea that blue light can effect their baby born with jaundice in the hospital. Did you know today's light specifically use blue light to get rid of the jaundice? The reason is simple......yellow is the color of jaundice and blue is its complimentary color therefore phototherapy using these wavelenghts. What is not well known is that blue light in children stimulates melanogensis and hyperpigmentation that lowers the ability to handle UV light. It is even associated with more nevi and more melanoma longr term. Phototherapy induces isomerization of bilirubin rendering it extractable because it becomes water soluble by altering the charge in the kidney's basement membrane allowing its easy clearance via the urine and hence it is used as a routine treatment of neonatal jaundice. What the article does not tell you is that pre-1950's full spectrum light was used and it was more effective. Then in 1959 a paper on retrolental hyperplasia of the eye showed up in the literature and caused all peditricians to begin avoiding UV light for this reason. They linked the two incorrectly. This one paper is why today modern medicine universally thinks UV light is always toxic. John Ott talked about this paper in his book "Heath and Light". You might want to read the paper and his book. Today's literature links uvela melanoma to early blue light exposure. These kids are all baked under blue light. Unlike cutaneous melanoma, however, ultraviolet radiation does not figure prominently among the risk factors for ocular melanoma, but blue light does seem to be linked to this new fast growing cancer. Eye melanoma is the fastest growing cancer of the eye today. Guess why? Blue light is behind it. This interesting observation of blue light effects to ocular melanocytes was followed up by a study that sought to mimic the effect of blue light on UM cells within the context of the mammalian eye. Human UM cells were xenografted into the eye of an albino rabbit model of ocular melanoma and subsequently exposed to blue light showed enhanced proliferation upon removal and recapture, compared with control samples protected from blue light. The significance of this finding is that the UM cells were exposed to blue light while residing within the choroid, effectively demonstrating that blue light affects uveal cells and can enhance their mitotic ability. This is a crucial step in linking blue light to malignant changes within uveal melanocytes in vivo. The final confirmation of the link between blue light and UM in vivo came from a study in Long Evans rats, a strain with pigmented eyes in which there have been no reported cases of intra-ocular melanoma. This study described the development of an ocular tumor in one animal following blue light exposure (434–475 nm). This is the range of the melanopsin receptor in the eye known to control melatonin production in the eye to control the entire central retinal pathways to the SCN.…/article/pii/S0306987716304169
