There are more reasons for patients to have blurred eyes when they get older, which are related to presbyopia, cataract, and fundus retinopathy. 1. Presbyopia: Presbyopia is one of the most common causes of blurred vision in the elderly. With age, the lens hardens and the ability to regulate decreases, and the patient may experience blurred vision when looking at objects. 2. Cataract: Cataract patients suffer from clouding of the lens, which leads to vision loss and blurred vision. 3. Fundus retinopathy: patients with ischemic optic neuropathy, age-related macular degeneration and other fundus retinopathies may also suffer from vision loss and blurred vision. It is recommended that patients with blurred vision should consult a doctor in time to evaluate their condition and follow the doctor’s instructions for treatment.
