With the popularity of electronic products, our life has been inseparable from the TV computer cell phone, although life has become better, but along with excessive eye use, myopia is also more and more people, more and more tends to be younger, and is gradually increasing! But the good thing is that there are glasses, is the glasses let us and “regain the light”. The glasses are very important to the majority of myopic people, and today we will talk about the glasses. The life span of glasses The life span of ordinary frame glasses is about 1-2 years, which also depends on the degree of wear and tear of the lenses, and changes in eye prescription to decide whether to replace, if not replace the glasses in a timely manner easy to produce dry eyes, eye acuity, visual fatigue and other discomfort, but also make myopia aggravated! The life of contact lenses is about 2600 hours, wearing contact lenses should be less than 8 hours a day, the longest do not exceed 12 hours, and do not wear contact lenses to sleep, because wearing contact lenses will make the cornea in a state of oxygen deprivation, serious cases will cause corneal infection, but also reduce the life of glasses! Some people think that eye deformation is the reason for wearing glasses, in fact, we really blame the glasses, it is because myopia after the visual axis becomes longer, so the eyes become convex, whether or not wearing glasses eyes will be deformed! The first thing you need to do is to do surgery. Some people think that myopia can do surgery, and in recent years myopia surgery has become more mature, so you don’t need to wear glasses and your eyes won’t be deformed. First of all, there are many restrictions to do surgery, age, degree, astigmatism, etc. Not everyone is suitable for surgery, and secondly, there are many post-operative complications, dry eye, keratitis, vision regression, etc.. The main thing is that there is a certain rate of blindness, although the chance is very low, but it is enough to discourage many people! Finally, we remind you that in order to avoid the continued development of myopia, you must pay attention to eye hygiene, keep your eyes at a distance, and don’t let your eyes work for too long either!
