Although the fly's compound eye consists of many small eyes, its vision is not good, and it can only see 40-70 mm. Its structure is a light collecting device like a convex lens, and many small eyes at the edges are gathered together, just like a wonderful kaleidoscope. Hanging with plastic bags filled with water, the water bag will be shaken by the wind through the refraction of solar light, producing dazzling light, affecting the fly's compound eyes, making it dizzy and not wanting to get close. At the same time, if the water bag does not shake, there is no way to drive away the flies. This is the principle of the water bag method.
