Presbyopia does not cause retinal degeneration, and the pathogenesis and treatment of the two are not the same. Presbyopia is caused by ageing and a decline in the eye’s ability to regulate the eye, making it clear at a distance and blurred at a distance. Retinal degeneration can be categorized into primary retinal degeneration and secondary retinal degeneration. Primary retinal degeneration is caused by congenital factors, while secondary retinal degeneration is caused by eye diseases. Primary retinal degeneration, such as retinitis pigmentosa, is caused by genetic factors. Secondary retinal degeneration is seen in high myopia, eye lesions, and systemic lesions that damage the eye, and treatment is mainly based on the cause. Presbyopia treatment, generally wearing presbyopia glasses can correct the patient’s symptoms of blurred vision. Retinal degeneration can choose laser photocoagulation and other therapies as prescribed by the doctor.
