Eyestrain may also cause short-term vision loss, but is usually reversible. Visual fatigue is a common ophthalmic condition, usually caused by spasms of the ciliary muscles inside the eyeball due to excessive contraction from prolonged close-up eye use. When the patient looks away again, the ciliary muscle cannot relax for a short period of time, and blurred vision may occur. However, after resting, vision can be gradually restored to normal. Patients with visual fatigue need to pay attention to develop good eye habits to avoid long-term eye fatigue, which can lead to eye soreness, blurred vision and other uncomfortable symptoms. Patients with obvious symptoms of visual fatigue can also follow the doctor’s instructions to use the seven leaves of digitalis biside eye drops and other medications to ease the symptoms of eye discomfort. It is recommended that patients with significant visual fatigue symptoms consult a doctor to assess their condition and follow the doctor’s instructions for treatment.
