It is normal for cataract patients to have clear vision at a distance and blurred vision up close after surgery. Cataracts are common in middle-aged and elderly people, and are related to the degeneration and aging of the lens of the eye, which becomes cloudy and blocks the transmission of light, affecting vision and requiring surgical treatment. After surgery, cataract patients may experience blurred vision at near and far distances. This is due to the fact that the IOL implanted in the eye does not have an adjusting function, which means that it is unable to move the focal point of the eye. In order to improve the near vision, patients can go to the ophthalmology department of the hospital to be prescribed glasses for near vision, so that they can see clearly when looking at the near distance with the glasses. In addition, it will take some time for the patient to get used to this condition.
