Can I wear contact lenses for astigmatism?

If you have astigmatism in your eyes and can't see far and near, can you only wear glasses? No no no锛?You may not know that contact lenses are also specially used to correct astigmatism, and the effect is great, but they are a little more elaborate than contact lenses that simply deal with myopia. Many contact lenses can solve partial astigmatism, such as: soft contact lenses: most brands can correct astigmatism within 75 degrees, > 75 degrees it is recommended to wear a special type of astigmatism correction hard contact lenses (RGP): according to the corneal situation, generally astigmatism within 300 degrees does not need additional correction, if the power is higher, you need to customize orthokeratology lenses (OK lenses): generally only corneal astigmatism can be corrected, and the range that can correct astigmatism is within 150 degrees. Astigmatism is caused by the "uneven curvature" of the cornea, which causes the light rays to refract at different angles and cannot be concentrated in the same focal point, so the image of seeing things is blurry. If it is regular astigmatism, the glasses are directional, and if the frame is displaced or not worn properly, the correction effect will not be so good. However, the contact lens that can correct astigmatism is tired, and it is achieved through a tear lens: tears will accumulate between the contact lens and the cornea, and the cornea will fill in where the tears are uneven, which is a good solution to the astigmatism on the anterior surface of the cornea. If you can't do it, you can also customize it. According to the doctor, contact lenses are filled with tears to correct astigmatism, which can effectively reduce aberrations, and if the myopia is relatively high and there is astigmatism, wearing contact lenses will be a little better than the visual quality of glasses. Irregular astigmatism is difficult to completely correct through glasses, so hard contact lenses (RGP) are a good choice, and the visual quality will be significantly improved.
