I have light in my eyes, too. The doctor said it was astigmatism.

Astigmatism is a common refractive error of eyes, which is related to the curvature of cornea. After parallel light enters the eye, because the refractive power of the eye is not equal on different meridians, it can't gather at one point (focus), and it can't form a clear object image. This situation is called astigmatism.

Astigmatism eyes can't form a clear image by adjusting or moving the distance between the target and the eyeball. Only by wearing a proper cylindrical lens can they form a clear image on the retina. According to the manifestations, astigmatism can be divided into regular astigmatism and irregular astigmatism. The former can be corrected with lenses, while the latter cannot be corrected with lenses.

The common symptoms of astigmatism eyes are:

1. Blurred vision: Blurred vision is closely related to the degree and mode of astigmatism. People with mild astigmatism usually have normal vision, but when they look at objects at a certain distance, they may have headaches or eye fatigue, and sometimes they will have double shadows when they see things.

2. Vision fatigue: The blurred images on the retina need to be fine-tuned constantly, and the vision is distorted, so astigmatism eyes, especially hyperopia astigmatism eyes, are prone to vision fatigue. Young patients with hyperopia and astigmatism can often cause vision by accommodation, so they ignore fatigue.

3. Head tilt: It is often caused by the fact that the balance of adjustment tension is destroyed when looking far, and the active head tilt makes one eye in a relatively clear position.
