How is it possible that all wavelengths converge to the same point on the sensor plane despite refracting differently?

It seems that the human eyes are also a compound lens that can change the focal length and aperture automatically.
For example, if we look at far objects or near objects, the scene is not blurred; and in dark or bright places, we can change the hole of our eye to control the radiance of light.
But our eyes do not have shutters, we can continuously perceive light. So eyes cannot integrate light for a long time. Maybe eyes will not generate any motion(temporal) blur because we do not integrate lights.
