A side-by-side visual comparison demonstrating the impact of LHON (Leber Hereditary Optic Neuropathy) on vision. The left panel, labeled "Healthy Vision," is a sharp, colorful photo of five young children joyfully running and holding hands in a park with fall foliage. The right panel, labeled "LHON Vision," shows the same photo but is significantly blurred and obscured by a large, cloudy gray patch centered over the image, illustrating profound central vision loss.
