Needs eye exam: If your father has diabetes and kidney failure, it is very likely he has diabetic retinopathy as well. This is diagnosed with a dilated eye exam. Blindness or blurry vision that lasts several seconds at a time could also represent ischemia or lack of blood blow to the eye or brain. This needs to be evaluated by his primary physician and an ophthalmologist.
