Abstract:
Smart Adaptive Eyewear is providing vision comfort to people with the help of shape changing
technique of liquefied lens by the help of actuators. Eyeglasses adjust the focus of lens by its own
and user adds the optical data through application. This project is for people who are facing
refractive error problem. Problems include Hyperopia (far sightedness), Myopia (near sightedness),
Presbyopia (lens can no longer can change their shape and cannot get focus to the vision),
Astigmatism (vision distortion because of irregular cornea curve) and blur vision. One ofthe reason
of having vision problem is loss in flexibility in eye muscles contraction and shape oflens that helps
the lens in the eye to adjust the focal length for a particular object. Due to bimorph as frequently their
bimorph changes. This project is delivering the frame with application through which user enters the
optical data. Eyewear contains transparent silicon membrane, battery to provide power,
microcontroller as main brain of device, piezoelectric actuators which are servo motors for the
movement of lens and transparent glass which is piston to provide hydrostatic pressure in lens and
make concave, convex shape of the membrane and as whole the device, it sense the distance and
adjust according to the focal length and optical power ofuser.
