Patient's question:
Distorted vision, mild edema, dilated pupils at night, poor night adaptation ability, and insensitivity to light at night.Doctor's answer:
Hello! Long-term vision fatigue does not cause visual distortion. An unsuitable glasses can sometimes cause visual distortion, but it only occurs when wearing glasses. Visual distortion can be caused by conditions such as keratoconus treated with mydriatics like pilocarpine, irregular corneal astigmatism, or macular lesions. Uncorrected myopia leads to poor night vision adaptation. A visual field test generally costs around 150 yuan.
