Problems with vision are usually caused by eye fatigue, trauma and disease, which need to be treated as soon as they are detected. 1. Eye fatigue: Excessive use of the eyes will lead to accelerated evaporation of water from the surface of the eyeballs, ultimately resulting in dryness and redness of the eyes, and may even lead to damage to the retina, resulting in vision loss. 2. Trauma: when the eye is hit or pressure and other stimuli, may also lead to vision loss phenomenon, so when the eye discomfort symptoms should be promptly to the hospital for examination to clarify the cause. 3. Diseases: Some diseases can also cause vision loss, such as cataract, glaucoma, optic neuritis and other eye diseases, as well as cerebral hemorrhage, brain tumors and other occupational diseases, can be caused to varying degrees of vision loss. If you have vision problems that are not relieved by rest and are accompanied by other discomforts, seek medical attention and treatment as prescribed by your doctor.
