Too much myopia. At least half of the people in the street wear glasses, most of whom suffer from myopia from teenagers. Glasses have become a lifelong object. Although everyone knows the importance of protecting eyesight, it is more common in reality that most people only pay attention to the degree, appearance and cost performance of glasses, but a good pair of glasses should not only consider these aspects. Today, Wenzhou Wanrun Glasses Co., Ltd. will discuss how to choose myopia glasses, which can help reduce the burden on the eyes and even meet your accurate needs.

The frame is not only beautiful and the right size can avoid eye injury. It seems to be the most unskilled thing to choose the frame when matching glasses. Would it be better for everyone to choose according to their own preferences? In fact, in addition to the appearance preference, you also need to pay attention to the size of the glasses, such as the width of the mirror, the width of the bridge of the nose, and the length of the legs. Just like buying clothes and shoes, mirror frames also have dimensions. It is important to cut clothes accordingly. If the size deviation is too large, it may lead to insufficient lens processing, and the pupil center deviates from the optical center of the lens. Glasses will produce prism effect, which will affect the comfort of wearing glasses. If it cannot be found in time, it may also affect the eye position after long-term wear.

Therefore, when configuring the lens frame, it is also necessary to find a professional optometrist to carefully measure the pupil distance and other key parameters, so as to carry out professional and accurate matching. Don't just look at thin and thick lenses. Comfortable and durable goggles. I believe those who have worn glasses have heard of the term refractive index of lenses. They know that the higher the refractive index, the thinner the lens, and the more expensive the natural price.

However, in addition to the influence of lens thickness on aesthetics, the optical properties of the lens should also be considered, such as dispersion coefficient, also known as Abbe number. When the refractive index is high, the Abbe number of dispersion coefficient will be low. What is the effect of low Abbe number? If the lens degree is high and the Abbe number is low, when viewing the highlight area such as the point light source, dispersion (rainbow stripes) may appear in the visual edge area, thus affecting the clarity and comfort. Therefore, you should choose the appropriate refractive index according to your degree to ensure clear and comfortable viewing.

Another key indicator of lenses is wear resistance. Wearing non wear-resistant lenses for a long time is likely to cause small scratches, which will affect visual clarity, and then easily lead to eye fatigue, directly affecting eye comfort. Therefore, it is very important to select lenses with high wear resistance. The selection points of the above frames and lenses can meet the basic needs of most people for glasses.
