Correction of astigmatism

summary

Astigmatism is a kind of abnormal refraction of the eye, which is related to the curvature of the cornea. Some people's corneas are curved at one angle, while others are flat. Astigmatism is caused by the uneven thickness of the cornea or the uneven curvature of the cornea, which makes the refractive rate of the meridians of the cornea inconsistent, so that the light passing through these meridians can not focus on the same focus, and the light can not accurately focus on the retina to form a clear image, which is called astigmatism. Is there any astigmatism correction method? So, what are the correction methods of astigmatism

Correction of astigmatism

1. If the astigmatism degree is high, you must wear astigmatism glasses. For long-term use of computers, precision workers or students who need to read and write for a long time, even mild astigmatism is best to wear astigmatism glasses.

2. Different from simple myopia, astigmatism fitting needs to determine the axial position and astigmatism degree. Therefore, in order to ensure the accuracy of fitting, it is best to choose a professional optometry center or eye hospital for examination before fitting.

3. In addition to the original frame astigmatism glasses, astigmatism contact lenses have become an effective tool to correct astigmatism, and have incomparable advantages over frame astigmatism glasses.

matters needing attention

For students who have been using computers for a long time, engaged in precision work or need to read and write for a long time, if the astigmatism is not corrected or the correction method is not correct, there will be discomfort such as sore eyes and around the orbit, and a few even have nausea and temporary blurred vision. Then, through the above introduction, I believe you have a further understanding of astigmatism correction methods.
