"From childhood to adulthood, every time I have a physical examination, what I am most afraid of is not weight or height, but vision!" I am afraid of hearing that my degree has deepened again. Many myopic friends must have had similar feelings and have felt the fear of being dominated by the eye chart.
Generally speaking, the eyeballs of minors are still in the developmental stage. As the eye axis lengthens, the degree of myopia will increase and the vision is still unstable. However, the eyeballs of adults are fully developed, the eye axis growth is relatively stopped, and the vision will basically stabilize.
However, some adults still have weakened vision. So why does this happen?
1. Pathological myopia
Myopia of more than 600 degrees is high myopia, which is divided into two categories:
① Simple high myopia: It can be stable after a certain period of development, and there is no serious change in the eye.
② Pathological myopia: It is a type of blinding eye disease that is different from simple high myopia, with abnormal extension of the eye axis, continuous deepening of myopia, and a rapid increase rate, and is often accompanied by complications such as cataracts, glaucoma, choroidal degeneration, and retinal detachment.
Pathological myopia is mainly caused by genetic factors. If there is high myopia in parents or family members, fundus and optometry examinations should be performed regularly.
2. Wearing inappropriate glasses
If the degree of glasses is too high, dizziness will occur. If the degree of glasses is insufficient, it is equivalent to looking at distant objects, the focus of the image still falls in front of the retina, and in a relaxed state, distant objects cannot be seen clearly.
At this time, the ciliary muscle responsible for adjusting the focal length will be over-adjusted and continue to spasm, which will easily fatigue over a long period of time and aggravate myopia.
3. Incorrect eye habits
Although adults have mature eyes and relatively stable myopia, if you have bad eye habits for a long time, such as looking at mobile phones, computers, iPads and other electronic devices for a long time, or using your eyes in an environment with too bright or too dark light, it is easy to cause visual fatigue.
If visual fatigue is not relieved in time, it will cause pseudomyopia. If it continues for a long time, it will become true myopia, and the degree will still increase.
