Abstract |
|
A large number of the population suffer from presbyopia. Presbyopia is an ophthalmic disease in which the person is not able to focus on near objects due to the hardening of the natural lens. In this paper, I have demonstrated an electromechanical spectacle which changes the diopter power as per the sight distance. The spectacle contains lead screw sliding mechanism and a pair of a concave and convex lens. When the wearer changes the sight, a distance sensor mounted on the spectacle measures a new sight distance and micro-stepper motor moves as per the algorithm and as a result, effective diopter power changes. The presented spectacle design can be used as an alternative for multifocal and progressive lenses. |
