Abstract: because the lens of large frame mirror is often too large, the “pupil distance” of the lens may also be larger. When some myopic people with small pupil distance are equipped with large frame mirror, it is equivalent to setting up a pair of prism in front of their eyes., Large frame glasses have always been favored by stars. Those who pay a little attention to fashion know that fashion queen Fan Bingbing often uses black large frame glasses to “Polish” her dress. It is not only a star, but also a must for trendsetters. It is not only fashionable, but also practical. Some girls choose large frame glasses for another purpose: to decorate the annoying “big cake face”., However, it is widely rumored on the Internet that wearing large frame glasses for a long time is likely to have cases of obvious visual loss, reduced visual field, dizziness and even vertigo. In addition, it also causes deformation and invagination of the nasal bridge, affects the development and ventilation of the nasal cavity, and induces rhinitis. The higher the degree, the greater the side effects., This statement has caused many people’s panic. Will big frame glasses really harm health?, Experts suggest that if the pupil distance is less than 60mm, it is not suitable to wear large frame glasses., “There are two important parameters for optometry glasses – diopter and pupillary distance. Big frame glasses often have problems with pupillary distance.” The doctor explained that the pupillary distance is the distance between the centers of the pupils of people’s two eyes. Generally, it is 60-62mm, but it is also narrower and wider. Glasses also have “pupil distance”, which refers to the distance between the optical center points of two lenses. The ideal state of matching glasses is that the “pupil distance” of the eyes and glasses coincide., Large frame lenses often have too large lenses, so the “pupil distance” of the lenses may also be larger. When some myopic people with small pupil distance are equipped with large frame mirror, it is equivalent to setting up a pair of prism in front of their eyes. The light will produce refraction, and the wearer is prone to ghosting when looking at things. Because the pupil distance error is too large, dizziness and brain swelling are easy to occur in a short time. In the long run, the harm is greater., Therefore, before matching glasses for myopia, be sure to measure the pupil distance. If the pupil distance is less than 60mm, don’t force to wear large frame glasses. If you want to be addicted to fashion, you can occasionally wear large spectacle frames without lenses. If it is flat lenses, you’d better remove the lenses. Although flat lenses have no degree, they are an “obstacle” to the eyes. If the lenses are stained with dust, they still have a certain impact on your vision.,
