If I'm not mistaken, its the clomid that effects your vision. I remember my last PCT, I had streaky/blurry vision on 100mg/day of clomid, it went away when i dropped down to 50mg/day. Some people have had permanent/semi permanent vision impairment. For me it wasnt anything that bothered too much, When I woke up is when I experienced it, and that probably had something to do with taking it at night before bed. The symptons didnt seem to last throughout the day.
