Deformation of font reading is usually caused by eyestrain, refractive error, macular degeneration and other reasons. 1. Eyestrain: Eyestrain usually refers to the self-conscious fatigue of the eyes, which is usually caused by prolonged use of the eyes, staying up all night, etc., and will lead to blurring of vision, asthenia, and other symptoms, resulting in distortion of the reading of fonts. 2. Refractive error: the presence of astigmatism and other refractive errors can also lead to visual abnormalities, resulting in distorted reading. 3. Macular degeneration: macula is an important structure of the eye, trauma, high myopia, etc. can lead to macular degeneration, which can cause distortion of vision, blurring of vision and other symptoms, resulting in distorted reading. If the deformation of the font persists and cannot be relieved by rest, patients are advised to go to the hospital for examination and treatment as soon as possible to avoid delaying the condition.
