Dew drops on grass can function as liquid magnifying
lenses that form images of objects around them. The eff ect
of light refraction is infl uenced by the size and shape of the
dew drops.
The thickness of the human eye lens is controlled by cilia
muscles so as to have diff erent focal lengths to form images in the
range of human vision. The concept of focal length adjustment
is applied by scientists and engineers to invent liquid camera
lens in smartphones. The focal length of the liquid lens can
be adjusted using electric fi eld in the electronic system of the
smartphone. As such, one liquid lens can replace a set of lenses
installed in the smartphone camera. The saving of space allows
the overall thickness of smartphones to be reduced.
