Visual symptoms refer to changes in vision that can indicate underlying health issues. These symptoms may include blurred vision, double vision, or difficulty seeing in low light. They can arise from various conditions, such as cataracts, glaucoma, or macular degeneration, and may affect one or both eyes. Common visual symptoms can also involve seeing spots, flashes of light, or a sudden loss of vision. These changes can be temporary or permanent and may require medical evaluation. Early detection and treatment are essential to prevent further complications related to eye health.
