Wenzhou Wanrun glasses manufacturers let you know the choice of glasses frames for myopia

Details

How should children choose to wear myopia glasses? Must children wear glasses if they have myopia? What should children do with 100 degree myopia? Myopia is a common disease in ophthalmology. If children have myopia, they must pay attention to it, because children's eyes are still in the process of development and maturity. Under normal circumstances, they will not completely stop developing until they are about 18 years old. Before this, there will be different degrees of myopia growth every year. If 100 degree myopia occurs at a very young age, After the age of 18, the possibility of high myopia is very high.

Many children like to follow the trend and choose large picture frames. As myopia glasses, according to the distance between the pupils, their own comfort is the main factor, and beauty is the auxiliary factor. Most lenses on the market are single-sided aspheric, so the inner surface is convex arc, and the thick edge transitions to the thin position of the optical center. During the processing of myopia glasses, the optical center must be aligned with the pupil to give full play to the large refraction effect of the lens.

After selecting the large lens frame, if the pupil needs to be aligned, there may be insufficient edges and insufficient lens width. In this case, many optician shops will choose to accommodate the frame and move the optical center away. This kind of glasses may be suitable for low-power glasses that are not often worn, but they will have side effects on the eyes, and people who wear high-power glasses will directly feel uncomfortable and uncomfortable.

This is called focus deviation. The lens center is thick, the thin middle pupil distance is small, the lens radius is insufficient and the pupil distance is large. The article is from the Internet. If there is any infringement or violation, please contact us for deletion.
