The most common causes of blurred eyes in 50-year-old patients are presbyopia and cataract. Presbyopia and cataract can not be adjusted through dietary therapy, you need to go to the ophthalmology department of the hospital in a timely manner for examination to identify the cause of blurring and treatment. For example, if the blurring is caused by presbyopia, it can be corrected by wearing close-up glasses; if it is caused by cataract, it can be treated by surgery.
Presbyopia is caused by the loss of eye adjustment function after ageing, and is mainly caused by blurred vision, which can be corrected by wearing close-up eyeglasses.
Cataracts, on the other hand, are caused by clouding of the lens, which blurs both near and far, and requires surgical treatment to improve vision.
None of these diseases can be restored through dietary therapy, and patients should follow their doctor’s advice and undergo regular treatment instead of blindly treating themselves.
