Abstract: astigmatism is caused by the incorrect beam of vision. It is an abnormal refractive condition, which is usually related to the radian of the cornea. The eye is always imperfect. The uneven curvature and thickness of the cornea will cause the light to not focus accurately on the retina to form a clear image. This situation is astigmatism., Myopia and astigmatism are common symptoms of the eye. In terms of etiology or physiological characteristics, myopia and astigmatism are essentially different. Although they can’t see clearly, they are really difficult to distinguish in the early stage. Myopia refers to that the eye can only see the near, but can not see the far, which is caused by the incorrect focus of vision; Astigmatism shows that one point can be regarded as multiple points., Astigmatism is caused by the incorrect beam of vision. It is an abnormal refractive condition, which is usually related to the radian of the cornea. The eye is not perfect. The uneven curvature and thickness of the cornea will cause the light to not focus accurately on the retina to form a clear image. This situation is astigmatism. General astigmatism will be accompanied by myopia and hyperopia, and will not appear independently., Myopia is on the premise of static refraction. Distant objects can only form a focus in front of the retina, and distant objects can’t be seen clearly. Many optical shops convert astigmatism degree into myopia degree. If the degree is high, it is easy to cause dizziness. Some people wear it for too long, and their eyes will be particularly tired. This is the reason., For contact lens wearers, if the astigmatism degree is more than 75 °, it is recommended to wear professional astigmatism customized tablets to ensure the health of both eyes. Those with low astigmatism can wear contact lenses with the function of correcting low astigmatism.,

and
myopia is that under the premise of static refraction, distant objects can only form a focus in front of the retina, and distant objects can’t be seen clearly. Many optical shops convert astigmatism degree into myopia degree. If the degree is high, it is easy to cause dizziness. Some people wear it for too long and their eyes will be particularly tired. This is the reason.
for contact lens wearers, if the astigmatism degree is more than 75 °, it is recommended to wear professional astigmatism customized tablets to ensure the health of both eyes. Those with low astigmatism can wear contact lenses with the function of correcting low astigmatism.
