DE> Sharon... <<SNIP>> Denise: Low level laser therapy has been in use for many decades. A simple search will result in reams of information, a lot of it published in the "respected" medical periodicals and journals. The lasers utilized are low level, and are NOT anywhere near as powerful as a surgical laser. Eye damage is only a concern if one stares into the beam. The beam will penetrate quite well through hair, but will be diffused. Other than staring into the beam, there are no real safety hazards in using a device like this. On the same note, if one cares to delve into the world of LLLT, you will find that there IS a point of the laser being too powerful. There exists a window of power levels which prove beneficial. Something not powerful enough yields no results, and something too powerful yields no results. Luckily for us, the low end extends below the power levels of superbright LED's (standard, superbright Light Emitting Diodes work wonders, as many on this list will attest), and the high end runs up quite a ways, but is far short of thermal tissue damage. While many have shown that the "ideal" wavelength is on the order of 660nm, anywhere in the red spectrum yields results. The "original" laser for this purpose was the helium/neon variety, which emits light at roughly 633 nanometers, and it had favorable results. Personally, I have found that superbright LED's show VERY acceptable results for many conditions, and eliminate the eye hazard. I do have a few that illuminate far better than a 5 milliwatt laser pointer, and I wouldn't look directly into them. Also, for some purposes, it seems that favorable results only manifest if the light is pulsed, as a constant, steady-state seems to result in no effect. Mind you, this is only for some purposes. -- Best regards, Solar -- The silver-list is a moderated forum for discussion of colloidal silver.
