What are the symptoms of astigmatism

First: visual fatigue: astigmatism due to the different refractive power of each meridian, refraction of parallel light can not form a focus, but two focal lines, so the brain is easy to produce selective interpretation of the image.

Second: vision loss: astigmatism away from the retina of the focus line direction of the target color becomes pale, the edge of the virtual unclear, not easy to identify, vision loss, severe diplopia.

Third: slightly heavy, regardless of distant objects, near objects, all feel blurred, patients often have the habit of half closed eyelids narrowed into a gap, in order to make the object see more clearly.
