Every single ommatidium independently forms its own tiny image of a very small part of the visual field. Put together, all these separate partial images combine into one composite, mosaic-like picture.
Step 2. What this gives functionally. This mosaic style of vision is described as being more sensitive to movement — even a slight movement of an object is easily detected, because it changes the pattern across many ommatidia at once — but it gives comparatively low resolution, meaning the image is somewhat hazy rather than sharply detailed. …
