![]() In the pages that follow, you will learn what lasers are and how they work, and about the therapeutic applications of low-level lasers that are now being researched. “Low-level”, “cold”, and “soft” lasers are all synonyms for lasers that work with one-half (0.5) a watt of power or less. Compare that to an everyday 60 watt light bulb and you get some idea of how low level and how soft these therapeutic lasers are!
The biological effects of low-level laser therapy (LLLT) have been studied for forty years all around the globe, and no unwanted side-effects have been noted anywhere. And, the safety record of LLLT is unparalleled in modern medicine. While theoretically the focused light of LLLT can be harmful to the eyes if stared into, there has been no documented case of damage to the eyes, either by clinicians or in the thousands of research studies completed since LLLT was first developed. Certainly, common sense precautions should be taken, and contraindications should be obeyed. See Precautions and Contraindications.
So, welcome to the new world of soft laser therapy! We have tried to arrange the material on soft laser therapy from short and simple to increasingly long and scientifically oriented. Choose the level of information you are comfortable with and have fun!
We are confident that this will be an interesting and enjoyable learning experience, and perhaps you will choose to introduce this healing light into your life and that of your friends and loved ones.
