The distorted vision is usually caused by astigmatism or macular edema and other fundus disorders.
Astigmatism is caused by optical distortion after refraction of light into the eyeballs, resulting in distorted images and double vision, which makes the vision chart appear distorted. Patients can be diagnosed through optometry and wear glasses to correct their astigmatism and improve their vision.
If the patient has macular edema, macular degeneration and other fundus diseases, due to the stimulation of the macular cells, there will be distortion of vision, and there will be a distorted feeling when looking at the visual acuity chart.
It is recommended that patients with abnormal vision should seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
