Distortion of vision is an inability to see clearly and correctly. Straight lines may appear bent, crooked, or wavy.
Usually this is caused by distortion of the retina, specifically in the macula area. This distortion can herald macular degeneration. If you have distorted vision, you should seek medical attention by an eye doctor promptly. Other conditions leading to swelling of the retina can cause this distortion, such as macular edema and central serous chorioretinopathy.
