Abstract

This study presents the design and analysis of a lens with a variable focal length, which we will call an adaptative lens. This lens is formed of two transparent elastic surfaces with a transparent liquid medium between them. The mechanical design of the lens considers the variation of liquid pressure between the surfaces. This causes changes in curvature radii and in the axial thickness, generating variations in the focal length of the lens. An analysis is given of changes in lens power with respect to changes in pressure. Finally, a model of the human eye is presented using this adaptative lens as crystalline.
