In general, safety goggles are not necessary for red light therapy because the wavelengths used in red light therapy are not harmful to the eyes. However, some manufacturers may recommend the use of goggles to protect against accidental exposure to brighter light sources or to reduce eye strain. If you are using Near Infrared Light , it is recommended that you wear protective eyewear, such as goggles rated for use with lasers, to protect your eyes from potential damage. Additionally, if you have a history of eye problems or are concerned about your eye health, it is always best to consult with a healthcare professional before beginning any new therapy.
