    In myopia, it is generally believed that 300 degrees below is low, 300 degrees to 600 degrees are moderate, 600 degrees to 800 degrees are high, and over 800 degrees is super high myopia.

    The division of astigmatism, however, is more stringent. Generally speaking, it is generally believed that: 100 degrees below is low, 100 to 200 is moderate, and more than 200 is high astigmatism. Strictly speaking, according to the "National College Optics Textbook" according to the degree of astigmatism, 75 degrees below is low astigmatism, 75 degrees above is high astigmatism!

    The same is 200 degrees, myopia is only mild, and astigmatism is high, such a gap can not be terrible?

    Wait a minute, about astigmatism, there's something more terrible:

    1. Optometry is cumbersome and difficult to adapt to.

    The refraction of astigmatism is more complicated than simple myopia and hyperopia, which requires accurate matching. And it is relatively difficult to adapt with mirrors. Many friends who wear astigmatism glasses for the first time will feel uncomfortable when they see things deformed, uneven ground, dizziness and deviation from distance.

    2. High astigmatism lenses have a long period of taking lenses and are more expensive.

    Most of the lens manufacturers on the market only stock up to 200 years of astigmatism, more than 200 astigmatism lenses need to be customized by manufacturers, it usually takes about a week to get glasses, and ordinary myopic lenses, many large physical stores can achieve the desirability of standing up, and the same lenses, customized astigmatism lenses prices to be much higher.

    3. Low astigmatism is more likely to cause visual fatigue

    Friends with low astigmatism often make themselves see more clearly by squinting and tilting their heads in order to improve their eyesight. This kind of continuous regulation can easily make eye muscles tense, relative myopia is more likely to cause headache, eye soreness and other visual fatigue.

    The harm of astigmatism is so great, how can we control and prevent it?

    Generally within 50 degrees of astigmatism, there is no visual fatigue or visual impairment, usually pay attention to eye health, usually pay attention to rest. If there is visual impairment, even if the degree is not high, we should actively cooperate with the treatment. Severe astigmatism may cause visual impairment, visual fatigue, corneal clouds, early senile cataract, keratoconus and even corneal perforation, so astigmatism must be detected and corrected as soon as possible.

    Like myopia, the simplest and safest way is to correct it with glasses. Surgery can also help correct astigmatism.

    Besides, keeping good eye habits is also a special need to pay attention to: do not lie on your side playing with mobile phones, do not squint, do not rub your eyes with your hands often!
