I have prescription inserts into my cycling glasses and on a number of occasions have had unidentified insects which appear simply as a large and moving blur, crawling between the two layers of plastic in front of my eyes. Always unsettling.
Reminds me of the time a bug crawled across the lens of my projector one night while I was watching a movie! :)
Damn near soiled myself when a 12" long bug suddenly crawled across the wall... Then realised what was going on. :)
