You might be able to do this on your own. do you use an android phone? if you do, you can use your google glass built in feature, all you have to do is screen capture the moment you see O'Neill on screen and make sure to edit the picture to only focus on his glasses, then use your google glass feature and then scan the image and it should bring up the exact brand of his glasses within several images.
If you don't have an android, i don't know how to help you. i'm not even sure iphone has an feature that is of equivalent to this feature
