I had a terrible experience with this doctor. The glasses he prescribed were too strong and I was suffering from headaches and pain in the eyes for half a year because of it. I didnÂ't realize it was from the glasses though. He told me it was from me not wearing the glasses all the time. After a couple of days of migraine I finally switched to my old glasses and the pain was gone. I'm just glad I figured this out (which is supposed to be his job).
