Question
Visual distortion with mild swelling, dilated pupils at night, poor night adaptation, and insensitivity to light at night.
Answer
Hello! Long-term eye strain does not cause visual distortion, but unsuitable glasses can sometimes lead to it, but only when wearing them. Visual distortion can occur due to factors such as astigmatism or irregular corneal astigmatism, or conditions like macular degeneration. Individuals with uncorrected myopia have poor night adaptation to light. Typically, the cost of a field test is around 150 yuan.
