They look quite real. I ordered these about two years ago and Im just now writing this review. Ive had to study them, and use them for almost the entire two years.

Overview:
1. Although they look real, they might fly off your face if you make any sudden head movements.
2. The lens can get really foggy. I know for me, any time I walked into a bathroom they instantly fogged.
3. Theyre pretty durable! Ive dropped them on concrete, wood flooring, and theyve survived without the lens breaking or scratching so thats cool.

So overall these are a nice pair of glasses if you want to prank your friends, or use them for cosplay... or if you just have a thing for wearing fake glasses.
