2022年3月16日 · Ommatidia — the tons of tiny lenses flies use to see — are bunched together in a globular shape to form a compound eye. The large, round shape of their eyes gives flies an almost 360-degree view of their surroundings.

Good fliers like flies or honey bees, or prey-catching insects like praying mantises or dragonflies, have specialized zones of ommatidia organized into a fovea area which gives acute vision. In the acute zone the eye is flattened and the facets larger.

2006年10月1日 · On page 696 of this issue, Zelhof and colleagues 1 reveal how flies improved the resolution of their eyes dramatically by evolving a specific modification to how their photoreceptor cells stick...

2012年10月11日 · Fly eyes have the fastest visual responses in the animal kingdom, but how they achieve this has long been an enigma. A new study shows that their rapid vision may be a result of their...

A fly typically has two compound eyes, each consisting of thousands of individual units called ommatidia. These compound eyes provide flies with a wide field of view, excellent motion detection, and the ability to perceive polarized light and some colors.

45 million years ago, a fly species was active in dim light. Now under microscope, scientists see the fly’s eyes had some very fine parallel corrugations.

A fly’s eyes are immobile, but their position and spherical shape give the fly an almost 360-degree view of its surroundings. Fly eyes have no pupils and cannot control how much light enters the eye or focus the images.
