Levaquin and bad vision

I'm not someone affected by Levaquin, but my boyfriend took Levaquin and now he has blurriness, visual snow, static, and halos. He's having really bad vision, yet his doctor says he has 20/20 vision. He is becoming suicidal and doesn't want to live anymore. He's been to over 30 doctors alone in a few months to find a cure and none of the doctors want to put a blame on Levaquin. He is losing hope and I'm losing hope. He seriously contemplates suicide everyday. Please someone help or e-mail me with anything you did to help your vision if you took Levaquin. If you saw any retina specialist or special doctors that cured the problems that Levaquin damaged. He's willing to fly anywhere in the world to get this fixed. He's going to try acupuncture for the eyes. What other remedies or things should he be trying? My e-mail is ******
