Black spots on the white of the eyes are mostly iris or conjunctiva color spots and pigmented nevi, which may be caused by physiological and pathological factors. 1. Physiological factors: black spots exist after birth or are related to growth and development, if they don’t affect vision, they don’t need to be treated, but if they grow rapidly, they should go to the hospital for medical checkup in time. 2. Pathological factors: there are two causes, namely, poor rest and periocular inflammatory stimulation. The former is due to poor rest or long-term response to the computer caused by eye fatigue, resulting in increased intraocular pressure caused by blood accumulation; the latter is due to foreign body stimulation or the presence of inflammation caused by conjunctivitis, manifested as black spots on the white of the eye. It is recommended that patients should go to the hospital to clarify the nature of the black spots, and under the guidance of the doctor for appropriate treatment.
