Airspace Structure; Human Factors
Flying at 5000 feet MSL. I was being vectored between ZZZ and ZZZ1. I was about 10 miles west of ZZZ2 when out of the corner of my eye; approximately at my 2:00; I started to see a pair of wings that were very quickly growing in my windshield. Within a second; the only thing I could see was a glider out my windshield. I had to take an evasive maneuver by disengaging the autopilot; climbing and turning to the north. It did not appear that the glider had seen me. I told the Controller what had happened and that an evasive maneuver had occurred. The Controller was polite and professional. They mentioned they had a primary target a bit to my north; but that was another glider; which I had a visual on. Neither glider was showing on my traffic page on my GPS; but this is understandable if they do not have electrical systems; and thus no transponders. The Controller gave me a vector further to the south; I assume to get me further and more quickly away from the glider port that is near ZZZ2. Made a practice approach into ZZZ1 with no further incidents.
C210 pilot reported an NMAC with a glider.
