Hospital optometry is accurate.
The optometry in the hospital belongs to the medical optometry, which is more professional and standardized, and the hospital pays attention to the development of vision in addition to the prescription of the glasses, while in the optician's store only pays attention to the prescription of the glasses, as well as the appearance of the glasses frames, and does not pay so much attention to the visual function, so in order to better check the vision what is wrong with the eyesight, it should be chosen to the hospital is more appropriate.
The view of the optometrist's bill
The optometrist's bill for myopia can be viewed in three parts.
The first part: marked with a capital letter S, which stands for spherical lenses, i.e., degrees of myopia and hyperopia. the numerical value of the S part refers to the specific degree of myopia or hyperopia, e.g., labeled ~2.0, which proves that it is 200 degrees of myopia, and +2.0 for 200 degrees of hyperopia.
The second part: labeled with a capital letter C, which stands for columnar lenses, i.e., astigmatism, and the value of the C part, which represents the patient's degree of astigmatism.
The third part: the A in the optometric list represents the axis of astigmatism, which is the direction of astigmatism. In addition, R is for the right eye, L is for the left eye, PD represents the pupillary distance, and SE represents the equivalent spherical lens, which is also positive or negative. ~ stands for myopia and + for hyperopia.
If the degree of myopia is relatively large, it is recommended to wear glasses or have vision correction early to help improve visual quality.
