Can I go to a special optical shop to see the eye degree?
Optical shops can measure numbers for free, but it is generally not feasible without glasses. Most optometrists do optometry for free, and finally they will tell the degree, but they will not give optometry data. Because they know that the data must have gone somewhere else to get the glasses. Buying glasses in a physical store is usually optometry. If you want to optometry data, you must want to match glasses online.

The accuracy of optometry in optical shops is largely related to optometrists, who receive many customers every day. If she wants to buy glasses, she will be very happy. If she just wants to have an optometry, she won't get it done. In this case, the eye data she said is probably false. Of course, this cannot be generalized.

Note: Don't choose a frame until you have the degree. Generally speaking, for low myopia, choose glasses frames according to your own preferences. For high myopia, it is recommended to choose small frames and thick frames. Regardless of the degree, after wearing the glasses frame, the geometric center of the glasses frame should coincide with or be as close as possible to the pupil center when farsighted. Nowadays, many girls like glasses with big frames, but the distance between their eyes is very small, which leads to the center of the pupil close to the inside of the frame.

Regardless of the appearance, it will reduce the optical correction effect and wearing comfort of the eyes. The higher the refractive index of the lens, the smaller the thickness of the lens edge. The choice of lens depends on the refractive index, and it is highly recommended to choose a higher refractive index. It is enough to choose low refractive index for low myopia, and it is not necessary to choose high refractive index lenses. Nowadays, many lenses have various functions: anti-blue light, high definition, and can also be selected according to their own needs.
