Bad kidneys do not affect the eyes. They are two different organs and are not necessarily related to each other. When both diseases occur at the same time, they show different symptoms. Most kidney diseases are urinary symptoms, such as frequent urination, urgent urination, hematuria and difficulty in urination, and the organs affected are mainly the bladder and ureter. Eye diseases show symptoms such as loss of vision, blurred vision and dry eyes, so there is no connection between the two. Therefore, do not worry too much. If kidney problems are accompanied by eye discomfort, you can go to the ophthalmology department in time.
