Watching TV for 2 hours may cause temporary deepening of myopia, usually due to ciliary muscle spasm, which can usually be recovered, but true deepening of myopia caused by prolonged TV watching usually cannot be recovered. The patient’s vision was normal before watching TV and the myopia did not change, while the vision decreased and myopia deepened after watching TV for 2 hours, usually due to pseudomyopia caused by ciliary muscle spasm due to overuse of the eyes, which can usually be recovered. The patient should pay attention to no longer use the eyes for a long time, so that the eyes can be relaxed and rested, thus the patient’s vision can be restored. If patients continue to maintain bad eye habits, long-term fatigue in the state of eye use, will eventually lead to true myopia, this type of myopia is generally not recoverable. It is recommended that myopia patients consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
