How much do you know about the harm caused by astigmatism to the eyes?
Astigmatism, a common eye disease, brings various inconveniences to our daily life and study. Many people know that most people with myopia have astigmatism, but they have never understood what astigmatism is. What kind of harm will it bring to the eyes? In order to make everyone pay attention to the health of the eyes, I will tell you about the ophthalmology problem of astigmatism today. First, astigmatism occurs from changes in the curvature of the cornea, that is, the light entering the eyeball cannot form a focus on the retina. According to the editor, there are two possibilities for the formation of astigmatism, one is congenital astigmatism, and the other is due to corneal disease (for example, after eye surgery, bad habits, etc.). The editor especially reminds everyone that under normal circumstances, pressing the eyeball with your fingers, the contraction of the eyelid or the action of the extraocular muscles can produce temporary changes in the shape of the eyeball, resulting in varying degrees of astigmatism. That is to say, maybe sometimes our eyes are uncomfortable, or when we feel itchy, we close our eyes and rub them vigorously. At this time, the eyeball will move upwards, and the pressure from the rubbing will gather under the eyeball, causing the curvature of the cornea to change. The uneven curvature of the cornea will cause astigmatism, which is related to the intraocular lens. Therefore, the editor reminds you not to rub your eyes casually, especially young people. When people suffer from astigmatism, it will cause a corresponding decrease in vision. The so-called astigmatism is the eye without focus. At the same time, astigmatism prevents the retina from concentrating in the same focal point, so whether you are looking at a distance or close, you will experience blurry symptoms, which can easily cause asthenopia. Finally, in order for everyone to have a pair of clear eyes, please develop good eye habits.
