Visual disorders refer to a range of conditions that affect a person's ability to see clearly. These disorders can result from various factors, including genetics, injury, or diseases such as glaucoma and cataracts. Symptoms may include blurred vision, difficulty seeing at night, or loss of peripheral vision. Common types of visual disorders include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, which are often corrected with glasses or contact lenses. More severe conditions, like macular degeneration or diabetic retinopathy, can lead to significant vision loss and may require medical intervention. Early detection and treatment are crucial for managing these disorders effectively.
