Why Does The Degree Of Myopia Continue To Increase Even With Myopia Glasses?
Myopia is caused by a combination of environment and genetics
First understand the causes of myopia: the currently recognized causes of myopia are environment and heredity. If one parent has high myopia (more than 600 degrees of myopia), then the probability of children suffering from myopia will be much higher. One of the things that is easily misunderstood in the heredity of myopia is that it is not hereditary myopia, but hereditary probability of myopia, that is, it is more likely to suffer from myopia.
Environmental factors are easier to understand, and the eye environment causes visual fatigue. Visual fatigue is the main cause of myopia. After myopia, in addition to blurred vision, the eye axis will undergo qualitative changes with the increase of the degree, and the eye axis will be elongated irreversibly.
Under normal circumstances, myopia will not increase after the eyeball matures (around the age of 18), but the reality is that even for middle-aged people, the degree of myopia still shows a trend of increasing after excessive eye use, although very slowly. It can be seen that environmental factors have crossed the bottom line of growth. The increase of myopia is not only affected by age, but excessive use of eyes is the culprit of its growth.
Bad eye habits
Most of the myopia is caused by poor eye habits. Many myopic patients have not corrected their poor eye habits after wearing glasses, such as the distance, time and posture of reading and writing. For example, too close a distance, too long time, lying down to read a book, too dark light, or even uncontrolled watching TV and playing game consoles, etc., can all cause spasm of the ciliary muscle in the eye, which can cause vision loss over time. Increased myopia.
When glasses are worn when they are not worn
Some people regard wearing glasses as a burden, fearing that it will hinder the appearance, and some people mistakenly think that the more they wear glasses, the deeper the degree, so they form the habit of wearing them sometimes and sometimes not. This will make the eyes often in an unstable state of accommodation for a long time, which may lead to increased myopia and decreased vision.
Glasses quality reasons
Whether there is an error in the optical center of the lens and the interpupillary distance, if it is myopic astigmatism, whether its astigmatism and axial position are accurate, these all determine whether a pair of glasses is comfortable to wear and whether it can achieve a good correction effect. The quality of glasses is very important to improve vision and reduce or eliminate eye fatigue. A pair of unqualified glasses can also cause vision loss and deepen myopia.
