What does astigmatism look like？
1. Decreased vision, which is closely related to the degree and type of astigmatism. People with mild astigmatism usually have normal vision, while those with moderate and high astigmatism have poor far and near vision. Simple astigmatism is mildly degraded, and complex astigmatism and mixed astigmatism are significantly degraded. Poor correction can lead to amblyopia.
2. Astigmatism, astigmatism requires continuous fine adjustment for blurred images on the retina, and visual distortion occurs. In particular, patients with hyperopia and astigmatism are prone to visual fatigue, manifested as eye pain, tearing, and headache, especially in the forehead, as well as double vision, and short-distance work cannot be sustained.
3. Compensatory head position and squinting vision, those with highly asymmetrical astigmatism in both eyes, in order to see more clearly, often adopt tilt head position to cause strabismus, which can be recovered after astigmatism correction. Sometimes, in order to get a larger retinal image, the patient often brings the object up close like a myopic patient. People with high astigmatism usually squint when looking at distant or near objects to achieve pinholes and fissures to improve vision. Seeing through pinholes or fissures can reduce the impact of astigmatism on vision.
