There are many eye diseases, such as myopia, astigmatism, and presbyopia. The so-called astigmatism is actually the inability of the eyes to focus on a single point when observing things. All of the above conditions can be corrected through correct treatment methods. The common correction method is to wear glasses, which will not cause any harm to the body. So what kind of glasses are used to correct astigmatism? First, what kind of glasses should be used to correct astigmatism? When having your eyes tested and getting glasses, if the astigmatism is high, you must wear astigmatism glasses. For students who use computers for a long time, engage in precision work, or need to read and write for a long time, it is best to wear astigmatism glasses even if they have mild astigmatism. Unlike simple myopia, astigmatism fitting requires determining the axis and degree of astigmatism. Therefore, in order to ensure the accuracy of fitting, it is best to choose a professional ophthalmology and optometry center for examination before fitting. Second, astigmatism glasses are used to correct astigmatism. There are two types of astigmatism: regular and irregular. Irregular astigmatism cannot be corrected with optical lenses, and only hard corneal contact lenses can be effective; while regular astigmatism can be corrected with optical lenses to improve vision. Many people believe that contact lenses do not have specialized astigmatism lenses. Actually, yes. This type of astigmatism lens adopts a series of high-tech designs, which successfully overcomes the problem of ordinary contact lenses rotating in the eye. It is comfortable to wear, has a high success rate in one fitting, and is simple and easy to fit, bringing great convenience to both optometrists and consumers. What kind of glasses can be used to correct astigmatism? In addition to the original frame astigmatism glasses, astigmatism contact lenses have become an effective tool for correcting astigmatism, and have advantages that frame astigmatism glasses cannot match. If a consumer with astigmatism is getting glasses, the usual practice is to subtract half of the astigmatism degree and add it to the myopia degree. In fact, the problem of astigmatism has not been solved, it has only deepened the degree of myopia. It may cause worsening of myopia and aggravate eye discomfort symptoms; vision may be corrected but astigmatism may still exist; symptoms such as headache and eye fatigue may occur. |
