Industrial flaw detection equipment generally uses lasers, if accidentally irradiate the eyes once, may cause eye damage to the patient, but the specific condition is related to the intensity of the laser. Industrial flaw detection equipment often use lasers as a light source for detection, and lasers have a higher energy density. If the laser directly irradiates the eyes, it may damage the patient’s eye tissues and structures, such as retinal macular burns, corneal epithelial defects, etc., which can lead to patients’ vision loss, eye stinging, dark area in the center of the field of vision, distortion of seeing, and other uncomfortable symptoms. However, if the laser irradiates the eyes for a short period of time, the damage to the eyes is small, so the patient’s discomfort symptoms are generally not obvious. However, patients should pay attention to protection at work to avoid re-injury to the eyes. It is recommended that patients with eye pain and other discomfort symptoms after being irradiated by laser should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
