Bystanders in the spa facility or medical treatment facility who are present to observe or to calm the patient (e. g., a patient’s relative) may be susceptible to exposure from reflected laser beams in the same manner as the professional staff. In addition, because of lack of training or knowledge about the laser surgical procedure, bystanders may be at a greater risk by inadvertently placing themselves in a dangerous position. Those individuals should always be provided with eye-protective goggles. It may also be wise to provide visitors with protective eyewear, even if not theoretically needed, since there have been incidences where individuals who discovered totally unrelated eye pathologies shortly after their visit blamed their experience in the laser-treatment facility.
