What are the common eye diseases?

Common eye diseases are diverse and can be mainly categorized into the following groups: 1. Refractive errors: Including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These conditions affect visual clarity and are among the most common ophthalmic problems. 2. Inflammatory diseases: Such as conjunctivitis and keratitis, usually caused by bacterial, viral infections or allergic reactions. Symptoms include redness, swelling, pain, and increased eye discharge. 3. Blindness-causing eye diseases: Glaucoma and cataracts are representative examples. Glaucoma is characterized by elevated intraocular pressure, which may lead to vision loss or even blindness. Cataracts involve decreased transparency of the lens, impairing light transmission. 4. Eye fatigue and dryness: Conditions such as dry eye syndrome and visual fatigue are commonly seen in individuals who use electronic devices for prolonged periods or live in dry environments. 5. Fundus diseases: Including retinal detachment and macular degeneration. Although less common, these conditions can severely impact vision once they occur. When experiencing abnormal symptoms such as eye pain, it is advisable to seek timely medical attention to maintain ocular health.
