I had extremely blurry vision & light sensitivity after Borrelia infection 2 years ago. I even noticed early on one pupil dilated while the other pinpoint which was scary to see in mirror, but was temporary. I took an eye vitamin supplement plus 3 rounds of oral antibiotics in 1st year of infection & my eyesight has since returned to normal. Borrelia infection is such a horrible life changing experience affecting brain, bladder & peripheral nerves, & joints longterm. Do everything you can to stop the infection with diet, antibiotics, supplements, etc. so you can get your immune system & life back to normal. Dont let Borrelia win.
