Wear glasses myopia still deepen? Because of this!

Abstract: many people tend to choose glasses with large black frame when wearing glasses. Most people think that the eye lenses are too small and the field of vision is limited. Choosing glasses with large frame not only can see clearly, but also looks elegant. Of course, this is also influenced by a kind of foreign fashion literary and artistic youth. However, we do not know that large black frame glasses may indirectly accelerate the degree of myopia. Let’s follow Xiaojian to learn about it. I hope it can help you., When wearing glasses, many people tend to choose glasses with large black frame. Most people think that the eye lenses are too small and the field of vision is limited.

many people prefer glasses with large black frame when wearing glasses. Most people think that the eye lenses are too small and the field of vision is limited. Choosing glasses with large frame not only can see clearly, but also looks elegant. Of course, this is also influenced by a kind of foreign fashionable cultural and artistic youth. However, we do not know that large black frame glasses may indirectly accelerate the degree of myopia. Let’s follow Xiaojian to learn about it. I hope it can help you.

large frame glasses may cause myopia to deepen. First of all, large frame glasses are heavier than other glasses. If they are worn for a long time, they will continue to put pressure on the bridge of the nose, resulting in deformation and invagination of the bridge of the nose. In serious cases, they will affect the development and ventilation of the nasal cavity, and it is easy to induce rhinitis. There will also be symptoms such as eye fatigue, soreness, numbness between the eyes or the bridge of the nose due to the compression of the nerves on the bridge of the nose and orbit. In addition, if the wearer lowers his head or shakes his head slightly, it is also easy to cause the glasses to fall. Secondly, the distance between the lens visual center of large frame glasses is difficult to keep consistent with the pupil spacing of people; The large frame of glasses often causes the optical center distance of the lens to be greater than the pupil distance, so the wearer will have symptoms such as decreased vision, reduced visual field, strabismus and dizziness. The longer the wearer wears it, the higher the degree of myopia, and the more obvious the side effects. Finally, the degree of each area of the spectacle lens is different. Generally speaking, the degree of the lens center is slightly lower than that around the lens, and our pupil focusing is based on the lens center point. If we often wear large frame glasses, it will be easy to decline due to the weight of the large frame glasses, resulting in the inability of pupil focusing to be consistent with the lens center point, resulting in visual impairment, And the continuous decline of vision. How to choose suitable myopia glasses {first is optometry. Let a professional optometrist test with a computer instrument, and then recheck it with a visual acuity chart to determine their accuracy. If there is astigmatism, it must be added. Then choose the lens according to your degree. If your degree is not very high, below 400 degrees, it is generally OK to match a resin coated anti radiation lens with a refractive index of 1.56; If your degree is slightly higher, below 600 degrees, it is better to match an aspherical lens with a refractive index of 1.56. The imaging of this lens is better, the surface of the lens is relatively flat, there is no difference, and the vision is clearer; If your degree is above 800 degrees, you’d better match a lens with a refractive index of 1.67 or 1.74. Such a lens is thinner. After wearing it, it will be much lighter and beautiful. There is also the choice of a slightly smaller frame, so the effect is better.
