What Causes Blurred Vision While On Medication For High BP?

hello i am 80 and am having blurry vision the past 10 days. I went to the Emergency room twice. All blood work, scans, urine come back normal. No glaucoma and no large/ripe cataracts. I take Xarelto, Crestor, and high blood pressure meds. What could be causing the blurry and sometimes double vision in one eye.
