Understanding Red Light Therapy

Red light therapy is a non-invasive treatment that uses red light-emitting diode (LED) light to deliver low-level light energy to the skin and other body tissues. It is a form of photobiomodulation therapy that has been used for various purposes, including skin rejuvenation, pain relief, and wound healing.

The therapy works by stimulating the production of adenosine triphosphate (ATP), a molecule that provides energy to cells. It is believed that the increased production of ATP helps to improve cellular function and promote healing in the treated area.

Red light therapy is also known as low-level laser therapy (LLLT), soft laser therapy, biostimulation, and photonic stimulation. It is considered safe and painless, with no known serious side effects.

However, there are concerns about the potential harm red light therapy may cause to the eyes. Some studies suggest that exposure to high levels of red light may damage the retina and lead to vision loss.

To minimize the risk of eye damage, it is recommended that individuals wear protective eyewear when undergoing red light therapy. The eyewear should be designed to block out the specific wavelengths of light used in the therapy.
