1. First of all, if it's not the first time to wear glasses, you should take the old glasses with you when you wear glasses before and when you're new. When you don't know all kinds of professional terms, you should take the old glasses with you. The optometrist in the optician's shop can master the degree and type of lenses used more accurately. In order to better understand your myopia.
2. Secondly, we should use professional optometry to measure the far / near sight degree, or astigmatism degree, axial position and pupil distance, etc. Confirm vision with bare eyes and glasses. That is to use the 'feeling' of the body to feel the clarity of vision. In the process of inserting the film for optometry, you should look at the distant and near objects, feel whether they are uncomfortable or dizzy, etc. no matter what the situation is, you should explain the situation to the optometrist in time, so that the optometrist can give you a more suitable degree. Special attention should be paid to that when testing vision, do not force yourself to guess the pattern and try to relax. Myopia, hyperopia, astigmatism, presbyopia and so on, these degrees need to be measured accurately, otherwise the optometrist will be misled, and the glasses will not be comfortable.
3. Third, make clear the main purpose of your glasses, whether you need to drive a car at ordinary times, how long you need to use the computer every day, whether you need to carry out fine handicraft operation, engage in color, design and other related work, etc. these information are very important for choosing glasses.
4. Finally, try to wear glasses with patience. You can't choose them casually. You need to wear them comfortably. After all, glasses need to be worn frequently. The comfort of wearing them is very important.
