Myopia of 500 degrees belongs to moderate myopia. If the eye has 500 degrees of myopia, the loss of naked eye vision must be very obvious, and from the perspective of vision check, even the largest line of letters on the vision chart is not visible. Therefore, when you go out, if you look at distant objects, it must be very unclear, and if you look at lights at night, it will also appear as a large band of light, which is not clear to see. For this situation, it is important to improve vision through various correction methods early, only then can we maintain clear visual quality and also slow down the development of myopia. Common methods of correction include frame glasses, corneal contact lenses or refractive surgery in adulthood.
