The full name of the slit lamp examination is slit lamp microscopy and does not cause any damage to the eye. Slit lamp microscopy is a commonly used ophthalmology examination equipment, which emits light through the lighting system to illuminate the patient’s eyes, and then observes the details of the patient’s eyes through the microscope system, so as to determine whether there are any ophthalmological diseases occurring, which is mainly used for the diagnosis of keratitis, conjunctivitis, cataract, iridocyclitis and other ophthalmological diseases. Although the light emitted by the slit lamp microscopy may make the patient feel too bright and harsh, causing discomfort, the intensity of the light is completely limited to a safe level, and will not cause damage to the patient’s eyes. At the same time, slit lamp microscopy is a non-contact examination, and no parts of the examination equipment will come into contact with the patient’s eyes, so it will not cause mechanical damage to the eyes.
