Ocular calculi: mostly formed by the aggregation and coagulation of detached epithelial cells and degenerated leukocytes, small and hard yellow dot-like protrusions appear on the surface of the conjunctiva, resulting in friction pain when the eye moves. 2. Optic neuritis: when there are inflammatory changes in the optic nerve, leading to edema around the optic nerve tissue. The optic nerve is irritated to some degree during eye movement, which can also cause pain. 3. Eye muscle fatigue: It may be due to lack of sleep at night, or long-term visual fatigue, causing the eyes to be in a state of fatigue for a long time, which will cause eye muscle pain when the eyes turn. When the eyes turn when the pain is caused by a variety of reasons, it is recommended to consult a doctor in a timely manner, in accordance with the doctor’s instructions for further examination, with the help of the doctor to clarify the cause, and targeted treatment or treatment.
