too funny,lol.
the fly has two eyes, one on each side of its head. each eye is a compound eye meaning the same facet is repeated 800 times (for fruit flies), each facet is called an ommatidia or simple eye. each ommatidia is composed of a set of photoreceptor neurons that detect light.
I bet Roberto's flies wear glasses! just a guess
OK, a million is high.... here is the Yahoo answer;
>>>In an
insects eye, there are many facets called
ommatidia that each have a corneal lens (like the cornea in
humans), crystalline cone (like the lens in humans), rhabdom (like the photoreceptors in humans), and a retinula cell.
However, even though their eyes have all these surfaces, the insect sees one single image and not a kalidescope of images like movies often portray. Insects have a very wide field of view and are great at detecting motion, but they are poor at seeing clearly at only about 20/1200.
Beetles have about 300 ommatidia, a dragonfly has about 25,000, a fruit fly has about 800, a horsefly has about 10,000<<<
Bottom line is each Rocky point beach fly has 10,000 eyes. But since they are never alone but swarm in groups of 1,000 minimum, that is one million eyes looking at you..
