A new study published in the Journal of American Medical Association showed that the safety profile of recurrent low-level red light (RLRL) treatment devices used to manage myopia varies. Two devices (Eyerising and Sky-n1201a) exceeded set safety limits for lasers and ophthalmic light exposure, according to investigators. Red laser therapy, or repetitive low-level red light, has become a popular treatment for myopia in Asia and is being considered more and more internationally. Overall, these results imply that during exposure intervals less than the suggested 180-second treatment duration, laser-based red light therapy devices provide irradiance levels that meet ANSI safety requirements.
