Abstract
An optical lens and varifocals, including a first transparent substrate and a zoom assembly. The zoom assembly comprises a first piezoelectric assembly and a second piezoelectric assembly, an air layer is formed between the second piezoelectric assembly and the first transparent substrate; a space is formed between the second piezoelectric assembly and the first piezoelectric assembly, and the space is filled with a transparent liquid to form a liquid layer; when voltages of the first piezoelectric assembly and the second piezoelectric assembly are changed, the first piezoelectric assembly and the second piezoelectric assembly are deformed to change surface curvatures of the liquid layer and the air layer.
