Interesting facts about Fly

1. Each eye has 3,000 lenses. (Simmons and Young, 1999)
2. Eye has a flicker fusion rate of 300/sec. Humans have a flicker fusion rate of only 60/sec in bright light and 24/sec in dim light. The flicker fusion rate is the frequency with which the "flicker" of an image cannot be distinguished as an individual event. Like the frame of a movie...if you slowed it down, you would see individual frames. Speed it up and you see a constantly moving image.
