Due to the increasing variety of glasses frames, more and more people are choosing glasses frames for nearsightedness, often only focusing on aesthetic issues. In fact, the optical and metrological technical indicators of glasses frames are very important for the comfort of consumers when wearing glasses. How to choose a glasses frame? We should consider the aesthetics, functionality, and comfort of wearing glasses from three aspects.
1. The size of the eyeglass frame
The eyeglass frame also has its own size, which is usually indicated on the eyeglass legs, nose bridge, or label with parameters such as the size of the eyeglass frame. Firstly, it is important to understand the size of the eyeglass frame that suits you. You can check the parameters of the purchased glasses, measure the matched glasses with a ruler to obtain data, or try on them at an eyeglass store, and then note down the size that suits you.
2. Knowing the degree of one's own eyes
The degree includes the degree of near/far vision of both eyes, as well as the distance between the pupils. If there is astigmatism, the degree of astigmatism and the axis of astigmatism need to be provided. The axis is the angle of astigmatism, and without the axis of astigmatism, astigmatism cannot be assembled. If you don't know the degree, you can go to an eyeglass store or a hospital to measure it.
3. The explanation of the optometry sheet
Remember to insert a lens for optometry (that is, try wearing a lens to look at the vision chart or looking far away, do not take the computer optometry sheet as a decree, even if there is a computer optometry sheet, it should be manually modified by inserting a lens for optometry). Those who wear glasses for the first time and those who rarely wear glasses must insert a lens for optometry, otherwise they may feel dizzy while wearing them. Regarding pupil distance, generally men have a pupil distance of 60mm-70mm, Ladies wear 58mm-65mm, with the center of the pupil and lens corresponding to the most comfortable fit.
4. Lens selection
If the degree of myopia is not high (0-300), choose a 1.56 refractive index. For moderate degree (300-500), choose a 1.61 refractive index. For slightly higher degree (500-800), choose a 1.67 refractive index. For high degree (800 and above), you can choose lenses with a higher refractive index. The higher the refractive index of the lens, the thinner the edges of the same degree lens, and the higher the price.
5. Suitable for facial shape and color matching
A round face is suitable for wearing a box, while a square face with a Chinese character and a melon seed face is suitable for wearing a round frame. Color matching should be based on personal preferences, while more mature individuals tend to prefer dark tones. Young people and those with a young mindset can try the trendy retro eyeglass frames recently.
Glasses frames are not just decorations on our faces, but also guardians of our eyes. The comfort and aesthetics of glasses frames are all factors we need to consider when choosing glasses. Only by considering all aspects can we maximize the effectiveness of glasses frames.
