AB - IntroductionOne of the recent research interests in intraocular lens (IOLs) technology is to achieve variable focal lengths by using suitable materials and novel designs. The most common solution is to either directly fabricate the lens and its components onto curved surfaces by moulding, or geometrically reshape a planar system. By far, all reported IOLs designs are of fixed focal length, the technical challenge remains to be addressed under the term of developing gel lens with adjustable focal length in an autonomous and reversible manner. From the perspective of customer experiences, the IOLs with self‐regulating focal length could offer convenient care solutions to perspective patients by providing vision tolerance to avoid over‐sight or/and over‐intensity after surgery.By applying various external stimuli such as temperature, pH, electric and magnetic fields, and chemical triggers, hydrogel can undergo reversible deformation to change its size and shape. Stimuli‐responsive hydrogels have been developed into various sensor and actuator applications include bio‐medical sensors, artificial muscle actuators, scaffolds for tissue engineering, active surfaces and drug delivery systems. The swelling and de‐swelling of the polymer network was firstly discovered as a result from reversible titration of weakly ionised polyelectrolyte gels. Given a proper boundary condition, curvilinear layouts could be
