Q: Do I need to wear glasses when I use red light therapy for knee?

Hi, red light therapy is equipped with red light glasses. When you use red light therapy for face, we recommend wearing glasses in order to avoid the damage of red light therapy to your eyes. But when you use red light therapy for body, red light therapy is almost harmless to glasses.
