Seeing straight lines as distorted

Seeing straight lines as distorted, also known as metamorphopsia, is a visual disturbance where straight lines appear wavy or bent. This symptom often indicates underlying retinal issues such as macular degeneration, retinal vein occlusion, or macular edema. Individuals with this condition might notice distortion while looking at grids or when reading text. An Amsler grid test, where they view a grid of straight lines, can help assess the distortion. Prompt medical evaluation is essential to diagnose and treat the underlying cause to prevent further vision impairment.
