What are the common eye diseases in humans?

Common eye diseases in humans mainly include the following: 1. Refractive errors: such as myopia, hyperopia, and astigmatism, characterized by blurred vision, which can be corrected with glasses or surgery. 2. Inflammatory conditions: such as conjunctivitis and keratitis, usually caused by bacteria, viruses, or allergies, with symptoms including redness, swelling, pain, tearing, and increased discharge. 3. Glaucoma: a disease characterized by elevated intraocular pressure that may lead to vision loss or even blindness, and has a certain genetic predisposition. 4. Cataracts: a visual disorder caused by decreased transparency or color change of the lens, commonly seen in older adults or individuals with underlying medical conditions. 5. Fundus diseases: such as macular degeneration and retinal detachment, which affect vision and may lead to blindness in severe cases. The development of these eye diseases may be related to various factors. When abnormal symptoms such as stabbing pain occur, prompt medical attention should be sought.
