When choosing glasses frames, many people often only pay attention to the appearance. In fact, the optical and metrological technical indicators of the glasses frames are very important for the comfort of wearing glasses. First of all, you need to know the size of the frame that suits you, which you can learn by looking at the parameters of the glasses you bought before. If you have never had glasses before, it is advisable to go directly to the hospital or optician to try them on and get your own prescription.

Generally speaking, round face is suitable for square eyewear frame and square face is suitable for round eyewear frame. The color matching is mainly referred to the personal preference, mature people are willing to choose dark ones, while the young people can try vintage glasses frames which are popular among individuals recently. Glitter glasses and pride glasses are also very suitable for summer.

Eyeglasses with straight lines can give a person a hard, professional, sharp feeling, especially suitable for commuting or the style of handsome people to wear. Rounded frames are more common and have many styles, such as round eyewear, oval eyeglasses, aviator glasses, cat-eye glasses and so on. Rounded shape can give you a soft, romantic feeling, which are more suitable for daily wear.

Precautions for the First Time of Getting Glasses

1. Before getting glasses, it is suggested to go to a professional optical store or hospital for optometry and checkup, so as to clarify the type of refractive error and the specific diopters. When you get eyeglasses, it is recommended to choose eyeglasses with correct prescription under the guidance of professional staff, which can effectively correct your vision and avoid the rapid growth of your diopters. You should avoid wearing eyeglasses with too much correction, because it will be counterproductive.

2. The thinner the lens, the lighter the weight. But you can't just pursue thin lenses, because the thinner the lens, the higher the refractive index. It may produce significant dispersion, leading to a decline in visual quality. If it is medium or low myopia, you don't need to pursue lenses with higher refractive index, it is just okay to use regular lenses.

3. Do not blindly pursue popular eyewear frames whcih are quite good-looking and can block your face almost all. However, it is definitely not suitable for people with high myopia. For people with a really high degree of myopia, this frame is a burden. Even if you use the thinnest lenses set in, it is super heavy and super thick, and it will definitely fall down all the time.

4. The pupillary distance is an indispensable parameter in the glasses. If the pupil distance is too small or too big, it will produce the corresponding prismatic degree, so that the wearer will feel heavy shadow or dizziness and other phenomena. Therefore, you should measure the pupillary distance before you get glasses, and then choose the glasses with the pupillary distance.

5. In order to save money, many people only replace eyewear lenses or eyewear frames at one time. But if you only change the lenses without changing the frames, then eyewear frames your newly bought may not be suitable for your current pupil distance and pupil height. If data changes, you may feel that the lenses are not as comfortable to wear. People with high astigmatism are generally very demanding in terms of pupil distance and height. The slightest change can make them feel uncomfortable.
