There is no clinical practice of assessing myopia on the basis of the number of rings in myopic lenses, and most of the myopic lenses cannot be assessed because the number of rings is not visible from the outside. If the refractive index of the lenses is the same, the myopia can be roughly assessed according to the thickness of the lenses, the thicker the lenses, the higher the myopia, while the thinner the lenses, the lower the myopia, but in general, it is not possible to judge the prescription of glasses by the circle of the glasses. If you need to clarify the degree of myopia you are wearing, we recommend that you go to a professional eye care dispensing organization for testing. If myopia leads to blurred vision and affects daily life, it is recommended that myopic patients go to the ophthalmology department of the hospital for examination in time, and if necessary, they need to have their eyes partially dilated after optometry, and according to the degree of optometry, they should wear the appropriate degree of myopic glasses to correct myopia, and to improve the patients’ visual acuity.
