There are ways to improve vision such as surgery, wearing glasses, and amblyopia training. In order to improve vision, the first thing to do is to identify the cause of vision loss and then treat the cause. If the problem is caused by refractive errors, including hyperopia, myopia and astigmatism, it needs to be diagnosed through optometry, and then corrected and treated with glasses and laser surgery to improve vision. If the vision problem is caused by amblyopia, it is necessary to improve the vision gradually through regular and long-term amblyopia training, such as traditional equipment training, CD-ROM training, Internet training and other modern training methods. If the problem is caused by cataracts, surgical treatment is needed to replace the cloudy lens inside the eye with a clear artificial lens to restore vision. It is important to follow the doctor’s advice and not to treat blindly.
