Vision loss is usually associated with myopia, hyperopia, amblyopia, etc. Depending on the cause of the problem, you may choose to wear eyeglasses or undergo surgery. 1. Myopia: It mainly refers to parallel light rays focusing in front of the retina, which leads to blurred vision. To treat myopia, you can choose to wear frame glasses or use corneal contact lenses. If your vision is relatively stable and you have reached the age of 18, you can choose to do femtosecond laser surgery. 2. Hyperopia: Contrary to myopia, it mainly refers to parallel light gathering behind the retina. It can be corrected by wearing frame glasses, or directly do laser surgery, such as excimer laser corneal surface cutting, excimer laser in-situ corneal resurfacing, and so on. 3. Amblyopia: related to the abnormality during the period of visual development, at present, the disease can be corrected by wearing corrective glasses, and then using the way of covering the dominant eye to make the weak vision gradually improve. If symptoms such as low vision and blurred vision occur, it is recommended to consult a doctor first to clarify the cause before choosing the appropriate treatment.
