If the prescription of the glasses is high, the lenses can only be replaced, there is no way to change them with the original lenses. If you have refractive errors, such as myopia, hyperopia or astigmatism, you must go to a regular hospital for an optometry examination. Only after an accurate optometry examination can you accurately understand the degree of refractive errors in your eyes and then go to wear glasses. If the prescription of glasses is not appropriate, such as too high or too low, it will have an impact on the eyes, and can cause serious eye discomfort, such as dizziness, headache, blurred vision, and over time will make the refractive error degree change. If you have myopia or astigmatism, you must go to a regular hospital to get your glasses fitted.
