Wenzhou Wanrun Glasses Co., Ltd.: Why are the new glasses uncomfortable as before

In the process of matching glasses, some customers sometimes report that they feel uncomfortable after wearing new glasses. They always feel uncomfortable and uncomfortable.

Details

In the process of matching glasses, some customers sometimes report that they feel uncomfortable after wearing new glasses. They always feel uncomfortable and uncomfortable. They feel different from the original glasses. All technical indicators of newly equipped glasses meet the requirements. If customers go back to adapt for a few days or even weeks, some people can accept glasses, while some people still can't accept glasses even after they have adapted for a period of time. Why? Wenzhou Wanrun Glasses Co., Ltd. will tell you! This often happens to people who are not wearing glasses for the first time. The old glasses also "transformed" the eyes during wearing, making the eyeballs more or less "abnormal". It is very difficult to match his glasses, especially with a suitable pair. The longer the history of wearing glasses, the more outstanding the performance of people with deeper degrees.

Under normal circumstances, the smaller the deviation between the optical center distance and the pupil distance, the better, so that the assembly is scientific and comfortable after wearing. If the optical center deviation of the patient's previous glasses is large and the degree is high (the requirements of different refractive states on the deviation of the optical center horizontal distance and pupil distance). The optical center of the new lens is determined according to the standard pupil distance. Wearing new lenses is likely to cause discomfort, such as dizziness, bending of visual objects, and less than one eye on both sides. The greater the diopter, the more obvious the reaction. Therefore, when matching glasses for customers, first measure the deviation between the horizontal distance of the optical center of the old glasses and the pupil distance, and calculate the prism degree at the corresponding pupil as a reference for matching new glasses. On the other hand, myopic objects are often adjusted with eye muscles, which is easy to cause visual fatigue and deepen the development. The use of transition optical center distance is not suitable for the elderly. It is better to keep the original state to avoid discomfort and other problems.

The inclination of the mirror frame leg refers to the angle between the normal of the mirror body plane and the mirror leg. Generally, there are 6 degrees, 8 degrees, 10 degrees and several specifications. Due to the deformation of many non-standard spectacle frames and spectacle frames in the process of wearing glasses, the influence of tilt on visual habits is formed. Because the position of the glasses legs is mostly connected to the upper part of the lens ring of the glasses frame, and because of the gravity effect of the glasses themselves, the optical center position of the glasses is offset when wearing. In this case, one solution is to let the patient adapt as much as possible, and the other is to adjust the leg inclination properly when the patient cannot adapt to make it close to the original mirror.

For some patients with large degree and long wearing history, the asymmetry of the optical center of the old mirror will hinder the wearing effect of the new mirror. The optical center symmetry of old glasses shall be measured when glasses are equipped. According to its diopter, calculate the influence of the corresponding prism degree at the pupil. The glasses can be made according to the state of the patient's old glasses. The article comes from the network. If there is infringement or violation, please contact us to delete it.
