Astigmatism may be the cause of double vision, but double vision is not the only clinical manifestation of astigmatism, it may also be caused by trauma and other eye diseases. 1. Astigmatism: the double vision caused by astigmatism is mainly dominated by double vision in one eye. Through refractive examination, it can be clear whether there is astigmatism and the degree of astigmatism, etc., which can be corrected by prescription lenses and help to alleviate the symptoms of double vision caused by astigmatism. 2. Trauma: For example, if the retina is damaged due to eye trauma, the phenomenon of double vision may occur. 3. Other eye diseases, such as corneal clouding and crystalline clouding, may cause double vision, and may be accompanied by reduced visual acuity and other symptoms. If you have double vision, it is not necessarily astigmatism, we suggest that you go to the hospital as soon as possible, improve the relevant examination to clarify the cause, and then deal with it under the guidance of the doctor.
