Presbyopia usually appears around the age of 45 and gradually worsens with age. Presbyopia, also known as presbyopia, is a common disease in ophthalmology. At the age of 45 or so, patients can gradually begin to experience symptoms of presbyopia, and with age, the degree of presbyopia will increase year by year, and at the age of 60 or so presbyopia will gradually stabilize, and the patient can wear presbyopia, that is, the near-use spectacles to correct presbyopia. Presbyopia is gradually formed due to the reduced elasticity of the lens inside the eyeball and the diminished regulatory function of the ciliary muscle as the patient grows older. Patients with presbyopia are unable to quickly and accurately focus their vision on near objects, which causes them to exhibit symptoms of clear vision at a distance and blurred vision at a near distance, and patients may experience discomfort such as difficulty in reading. It is recommended that patients with presbyopia consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
