Selection of spectacle lenses for high myopia

How to choose the right lens for high myopia? If the lenses are too thick, how can you make your eyes look personal and comfortable after wearing glasses? Here are a few ways to choose spectacle lenses for high myopia. Of course, the lenses should be thin, so you need to choose lenses with a high refractive index, so that they can be thin, and the frame is relatively small, so that the whole glasses look who will know that you are highly myopia? The lens power of the corrected high myopia eye is very high, and the periphery is thick and the center is thin. There are several ways to reduce the thickness around the lens, and it is a good idea to choose such lenses: (1) Choose smaller frames: Large frames not only increase the thickness around the lens, but also increase the weight of the lens. (2) Choose lenses made of materials with high refractive index: The refractive power of this lens is stronger than that of ordinary lenses, so it can be made thinner. High refractive index lenses have strong light reflection on the surface, so it is best to use lenses with an anti-reflective coating. (3) Choose aspherical lenses: This kind of lens can reduce the thickness of the center of the lens, reduce the weight, and reduce the optical distortion. (4) Do not use rimless frames: because such glasses need to add unnecessary lens thickness and weight. (5) Choose plastic lenses: For most patients, it is better to choose plastic lenses, because the weight of plastic lenses is only half of that of glass lenses, and the anti-ultraviolet function is better, not easy to break, and easy to stain. (6) Choose polycarbonate lenses: These lenses are the least likely to break, and are especially suitable for children and athletes. People with myopia who wear polycarbonate lenses with a diopter of -7.00 or higher may have scattered colored fringes when looking at light through the periphery of the lens. The above are several ways to choose spectacle lenses for high myopia, and choosing the right one is the best.
