It is necessary to choose a qualified organization to ensure the accuracy of optometry and the correct choice of frames and lenses. 1. Choose a qualified optician: Before choosing glasses, patients should find out whether the organization they choose has qualified optometrists and dispensing equipment. It is recommended that patients choose an authoritative organization to avoid unsuccessful dispensing of glasses which are not suitable for them. 2. Accuracy of optometry: Patients need to undergo optometry before getting glasses, which can accurately determine the condition of the patient’s eyes, and the dispensing optician can accurately dispense glasses according to the optometry data. If the optometry is inaccurate, the patient may experience blurring or dizziness and other uncomfortable symptoms after being fitted with glasses. 3. Correct selection of frames and lenses: When selecting frames, patients should keep the position of pupil and optical center of glasses compatible. When choosing lenses, it is recommended to choose the lenses with good clarity and light weight, which is favorable to the patients’ normal life after wearing glasses. It is recommended that patients who need glasses should go to a professional organization to get glasses, and consult the doctor in time after discomfort occurs.
